    were convicted and received lengthy prison sentences.                On appeal, Lopez,
    Garza, and Zamora allege a variety of errors were committed at trial. In
    * Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not

    addition, Garza and Zamora challenge their sentences. After careful review of
    the record and relevant case law, we affirm their convictions and sentences.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    A.     Factual Background 1
    This appeal concerns a conspiracy to smuggle large quantities of
    marijuana from Mexico into the United States, involving at least a dozen
    individuals, from 2003 to 2012. At trial, the Government primarily relied on
    testimony from the following individuals, all of whom admitted to being
    involved in the drug conspiracy: Jesus Marroquin; Ronny Rice; Edward David
    Mata; Richard Patton; Servando Guerra; Luis Andreas Longoria; Jose Maria
    Carbajal, Jr.; Rene Salazar, Jr.; Jose Figueroa; and Adrian de la Garza. The
    Government also offered testimony from numerous law enforcement officials
    involved in investigating the conspiracy.
    Jose Maria Carbajal, Jr. (“Carbajal”) began trafficking marijuana in the
    mid-to-late 1980s.        Initially, he carried 20-pound loads of marijuana in
    backpacks through Encino and Falfurrias. Carbajal later met another supplier
    and began moving larger loads of approximately 150 to 200 pounds. Carbajal
    and his associates, Edward Mata (“Mata”) and Richard Patton (“Patton”), used
    ATVs and night-vision goggles to trespass through ranches near the Falfurrias
    Border Patrol Station to smuggle the marijuana past the checkpoint.
    Sometime around 2005, Lopez learned of Carbajal’s operation, and he
    approached Carbajal to offer Carbajal the use of his ranch, Las Carolina Ranch
    (“Carolina”).     Before beginning their working relationship, Lopez asked
    Carbajal to pass a test: he wanted Carbajal to move some marijuana belonging
    1 Because this appeal involves a challenge to the sufficiency of the evidence, we review
    the facts “in the light most favorable to the jury verdict, including all reasonable inferences
    and credibility choices.” United States v. Pierre, 
    958 F.2d 1304
    , 1310–11 (5th Cir. 1992) (en
    banc). We discuss any relevant disputes about the facts in the appropriate sections below.
    See infra subparts III(B) and IV(E).

    No. 13-40203
    to Damien Solis, a drug trafficker, through Lopez’s ranch past the Falfurrias
    Border Patrol Station. Carbajal passed the test, and he introduced Jesus
    Marroquin (“Marroquin”) to Lopez. Carbajal told Lopez that he and Marroquin
    would begin using Carolina. For the next seven years, Marroquin and Carbajal
    moved loads of marijuana through ranches including Carolina, transporting
    more than 25,000 pounds of marijuana into the United States.
    In 2006, Lopez asked Carbajal to come to a meeting with Garza. Garza
    had been trafficking in marijuana since at least 2004, using an employee,
    Ronny Rice (“Rice”), to drive shipments into the United States. Soon after the
    meeting between Lopez, Carbajal, and Garza, Garza’s brother, Alex Garza,
    began delivering shipments to Carolina.               According to Carbajal’s trial
    testimony, “[t]hat’s where the big quantities started coming in.” The Garzas
    and other distributors dropped off 500-to-1,500-pound loads of marijuana at
    Carolina. Phone records revealed that Lopez was in frequent contact with
    Carbajal and Garza. As the operation grew, Lopez decided to build an outhouse
    with a false bottom on his ranch for the smugglers to conceal the marijuana.
    The outhouse could hold between 1,000 and 1,500 pounds of marijuana.
    Carbajal also used other ranches in addition to Carolina. He formed a
    relationship with Zamora, who was employed at Baluarte Ranch, which was
    also near the Falfurrias checkpoint. 2 Zamora helped Carbajal and two of
    Carbajal’s associates to get jobs at Baluarte Ranch. Carbajal and others then
    began smuggling marijuana through Baluarte Ranch; Zamora would help
    them gain access the ranch and provided them places to store the marijuana.
    They stored marijuana at Baluarte Ranch as often as two to three times a week
    for three years and at least fifty times. Zamora also served as a lookout against
    2 The parties and the record refer to the ranch where Zamora worked as both Baluarte
    Ranch and the Hector Lopez Ranch. Both names identify the same property though, and for
    the sake of consistency, we refer to the property as Baluarte Ranch.

    law enforcement officers. The conspiracy entered its most successful phase
    once Zamora started working with Carbajal.
    While investigating the conspiracy, the Government seized marijuana on
    a number of occasions between 2003 and 2012. They recovered marijuana from
    a number of Carbajal’s employees, Ronny Rice, and from Carbajal and Garza
    themselves. Among the largest amounts recovered were 3,000 pounds from
    Garza’s home, 2,000 pounds hidden in a truck Patton had abandoned, and
    1,400 pounds from a trailer.
    Carbajal was arrested in early 2011. Law enforcement officials had
    begun to suspect Lopez’s involvement in the conspiracy, and they interviewed
    him after Carbajal was arrested. They later returned to his ranch to execute
    a search warrant, and they discovered an illegal alien, Marvin Ruiz (“Ruiz”),
    whom Lopez employed as a ranch hand. Lopez was charged with harboring an
    illegal alien. When the Government interviewed Ruiz, he told them that he
    did not have any knowledge of illegal activity at the ranch. The parties dispute
    when Lopez was made aware of this statement. See infra subpart III(D)(2).
    Lopez agreed to allow the Government to release Ruiz from custody and
    remove him from the United States before Lopez’s conspiracy trial.
    B.    Procedural Background
    In 2012, Lopez, Zamora, Garza, and nine coconspirators were indicted
    for conspiracy with intent to distribute more than 1,000 kg of marijuana in
    violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(A), and 846. Lopez, Zamora, and
    Garza went to trial, and the jury found all three guilty. Lopez was sentenced
    to 292 months’ imprisonment with 5 years of supervised release. Zamora was
    sentenced to 360 months in prison, followed by 5 years of supervised release.
    Garza was sentenced to life in prison to be followed by 10 years of supervised
    release.

    II. JURISDICTION
    The district court had jurisdiction under 18 U.S.C. § 3231. This Court
    has jurisdiction pursuant to 28 U.S.C. § 1291 and 18 U.S.C. § 3742.
    III. DISCUSSION
    Lopez, Garza, and Zamora each raise a number of issues on appeal. We
    address these issues in the following order. First, Zamora argues the district
    court erroneously denied his motion to suppress evidence.         Second, both
    Zamora and Lopez challenge the sufficiency of the evidence supporting their
    convictions. Third, Garza argues there was a material variance between the
    charge in the indictment and the evidence at trial. Fourth, Lopez claims the
    Government committed a Brady violation because it failed to timely disclose
    exculpatory evidence. Finally, both Garza and Zamora argue that the district
    court erred in calculating their sentences. We address each issue in turn.
    A.    Zamora’s Motion to Suppress
    1. Standard of Review
    When reviewing a district court’s denial of a motion to suppress, this
    Court reviews “factual findings for clear error and legal conclusions regarding
    the sufficiency of the warrant or the reasonableness of an officer’s reliance on
    a warrant de novo.” United States v. Allen, 
    625 F.3d 830
    , 834 (5th Cir. 2010).
    We “view the evidence in the light most favorable to the prevailing party, in
    this case, the United States.” 
    Id. 2. Analysis
          When reviewing the denial of a motion to suppress evidence under the
    Fourth Amendment, this Court conduct an alternative test. United States v.
    Gibbs, 
    421 F.3d 352
    , 357 (5th Cir. 2005). First, we consider whether the good-
    faith exception applies, that is, whether “the officer executing the warrant
    relied on it in good faith.” 
    Id. “For the
    good-faith exception to apply, the
    executing-officer’s   reliance   on    the    issuing-judge’s   probable-cause
    5
    Case: 13-40203      Document: 00512780393        Page: 6     Date Filed: 09/24/2014
    No. 13-40203
    determination and the technical sufficiency of the warrant must have been
    objectively reasonable.” 
    Id. at 358.
    A warrant will ordinarily establish good
    faith on the part of the officer executing the warrant. United States v. Craig,
    
    861 F.2d 818
    , 821 (5th Cir. 1988). But the warrant will not establish good faith
    if the affidavit supporting the warrant is bare bones, meaning it is “so lacking
    in indicia of probable cause as to render belief in its existence entirely
    unreasonable.” 
    Id. (citation and
    internal quotation marks omitted). If the
    good-faith exception applies, the inquiry ends; if this Court does not find good
    faith, we will next consider “whether the warrant was supported by probable
    cause.” 
    Gibbs, 421 F.3d at 357
    (citation and internal quotation marks omitted).
    Even if both of these tests are met, this Court still applies a harmless error
    analysis, which asks “whether the trier of fact would have found the defendant
    guilty beyond a reasonable doubt [if the evidence had been suppressed].”
    United States v. Willingham, 
    310 F.3d 367
    , 372 (5th Cir. 2002) (alteration in
    original) (citation and internal quotation marks omitted).
    Zamora argues that the district court erred in denying his motion to
    suppress because the search warrant used to search his house listed the wrong
    address. 3 He points out that the search warrant authorized the search of 2932
    Fernando Salinas, Rio Grande City, Texas, but that the address of his home
    and the house the agents actually searched is 2930 Fernando Salinas, Rio
    Grande City, Texas. Zamora claims that because of the incorrect address, the
    warrant did not give the officers a basis for searching any residence other than
    2932 Fernando Salinas. He also claims the good-faith exception does not apply
    3  The agents who searched Zamora’s home found “a grenade, 46 firearms, various
    magazines for the firearms, two ballistic vests, a lot of ammunition, about 4 ounces of
    marijuana, a pair of night vision goggles, [a] steel baton, handcuffs, [an automobile], and
    miscellaneous documents.” At trial, the Government argued that finding the night-vision
    goggles at Zamora’s home corroborated the coconspirators’ testimony that they used night-
    vision goggles to get around the ranches while transporting drugs at night.
    6
    Case: 13-40203    Document: 00512780393     Page: 7   Date Filed: 09/24/2014
    No. 13-40203
    because the affidavit failed to state probable cause for the agents to search
    2930 Fernando Salinas. The Government responds that “[t]he district court’s
    findings of fact, which were based on testimony offered at the suppression
    hearing, establish both the validity of the warrant and the agents’ reasonable
    reliance on it.” According to the Government, the warrant was not facially
    invalid because it accurately described the premises to be searched, and the
    agents’ reliance on the warrant was objectively reasonable.
    We hold that the district court did not err when it denied Zamora’s
    motion to suppress because the good-faith exception applies. We focus on
    whether the warrant describes the premises to be searched with sufficient
    specificity to ensure that the officers could locate the premises without
    searching the wrong premises. See 
    Darensbourg, 520 F.2d at 987
    (“It is enough
    if the description is such that the officer with a search warrant can, with
    reasonable effort ascertain and identify the place intended. The test is one of
    reasonableness, and [t]echnical requirements of elaborate specificity once
    exacted under common law pleadings have no proper place in this area.”
    (alteration in original) (citations and internal quotation marks omitted)). An
    incorrect address is not necessarily fatal.
    Indeed, this Court has previously upheld searches conducted pursuant
    to warrants with an incorrect house number, the wrong street name, and even
    the incorrect city. See, e.g., United States v. Gordon, 
    901 F.2d 48
    , 50 (5th Cir.
    1990) (even though the street name was wrong on the warrant, the good-faith
    exception applied because the defect was not apparent from simply looking at
    the warrant, “the affiant [who was] the executing officer . . . had recently
    viewed the location in question,” and “there was no possibility the wrong
    premises would be searched” (internal quotation marks omitted)); United
    States v. Avarello, 
    592 F.2d 1339
    , 1344 (5th Cir. 1979) (affirming denial of the
    motion to suppress where the warrant listed the wrong city because the
    7
    Case: 13-40203   Document: 00512780393    Page: 8   Date Filed: 09/24/2014
    No. 13-40203
    description of the premises allowed “the executing officers [to] locate and
    identify the premises to be searched with reasonable effort”); United States v.
    Darensbourg, 
    520 F.2d 985
    , 987 (5th Cir. 1975) (collecting cases where the
    Fifth Circuit has upheld the denial of a motion to suppress when the address
    was incorrect).
    Here, the officers initially set out to execute an arrest warrant for
    Zamora, which listed his address as 2930 Fernando Salinas.         When they
    arrived at the street, they were unable to find 2930, but they saw Zamora’s car
    parked outside a house that had an electrical box labeled 2932. The agents
    executed the arrest warrant, and then sought a search warrant, which listed
    the address of the home as 2932 Fernando Salinas. The search warrant also
    gave a physical description of the home, noted that Zamora had been found
    inside the home, and stated that 2932 appeared on the home’s electrical box.
    The district court found that the warrant accurately described Zamora’s
    home so that the officers would not risk searching the wrong home. Zamora
    does not dispute the accuracy of the description of his home in the warrant; he
    only focuses on the incorrect address. But, as the cases above demonstrate, an
    incorrect address in a search warrant does not automatically invalidate the
    search. Because the warrant accurately described Zamora’s home, the officers
    were able to find his house and there was little risk that they would
    inadvertently search the wrong location. Thus, the district court correctly
    denied Zamora’s motion to suppress.
    B.    Sufficiency of the Evidence (Lopez and Zamora)
    1. Standard of Review
    Both Lopez and Zamora admit that they failed to move for a judgment of
    acquittal on the grounds that the Government had not presented sufficient
    evidence to convict them. This Court reviews unpreserved challenges to the
    sufficiency of the evidence for plain error. United States v. Delgado, 
    672 F.3d 8
        Case: 13-40203     Document: 00512780393       Page: 9   Date Filed: 09/24/2014
    No. 13-40203
    320, 330 (5th Cir. 2012) (en banc). Under plain error review, the defendant
    “must show: (1) an error, (2) that is plain, (3) and that affected his substantial
    rights.” United States v. Garcia–Gonzalez, 
    714 F.3d 306
    , 315 (5th Cir. 2013)
    (citation omitted). Even if the Defendant–Appellant satisfies those criteria,
    this Court “will exercise discretion to correct the error only if the error seriously
    affect[s] the fairness, integrity or public reputation of judicial proceedings.” 
    Id. (alteration in
    original) (citation and internal quotation marks omitted).
    This Court has previously “described the standard of review for
    unpreserved insufficiency claims in the most exacting language, stating that
    such a claim ‘will be rejected unless the record is devoid of evidence pointing to
    guilt or if the evidence is so tenuous that a conviction is shocking.’” 
    Delgado, 672 F.3d at 330
    –31 (quoting United States v. Phillips, 
    477 F.3d 215
    , 219 (5th
    Cir. 2007) (emphasis added) (internal quotation marks omitted)). “Put simply,
    to satisfy the second prong of the plain-error test, [the defendant] must
    demonstrate not just that the government’s evidence of conspiracy was
    insufficient, but that it was obviously insufficient.” 
    Id. at 331.
    This Court
    reviews “the evidence in the light most favorable to the jury verdict, including
    all reasonable inferences and credibility choices.” United States v. Pierre, 
    958 F.2d 1304
    , 1310–11 (5th Cir. 1992) (en banc).
    2. Analysis
    “To prove conspiracy to possess and distribute a controlled substance,
    the government must show beyond a reasonable doubt (1) the existence of an
    agreement between two or more persons to violate narcotics laws; (2) the
    defendant’s knowledge of the agreement; and (3) his voluntary participation in
    the conspiracy.” United State v. Valdez, 
    453 F.3d 252
    , 256–57 (5th Cir. 2006)
    (footnote omitted). The Government cannot prove a conspiracy merely by
    showing a defendant’s presence at a crime scene or association with
    conspirators.    
    Id. at 257.
         But “[a] conspiracy may be inferred from
    9
    Case: 13-40203     Document: 00512780393    Page: 10   Date Filed: 09/24/2014
    No. 13-40203
    circumstantial evidence.” United States v. Villegas–Rodriguez, 
    171 F.3d 224
    ,
    228 (5th Cir. 1999). The Government is not required to prove “that each
    defendant knew of every detail of the conspiracy, only that each knew of its
    essentials.” 
    Id. Importantly for
    this case, “a defendant may be convicted on
    the uncorroborated testimony of a coconspirator who has accepted a plea
    bargain unless the coconspirator’s testimony is incredible.” 
    Id. “Testimony is
    incredible as a matter of law only if it relates to facts that the witness could
    not possibly have observed or to events which could not have occurred under
    the laws of nature.” United States v. Bermea, 
    30 F.3d 1539
    , 1552 (5th Cir.
    1994).
    a. Lopez
    Lopez’s main argument about the sufficiency of the evidence is that it
    was uncorroborated and unreliable. Specifically, he complains that
    The only evidence offered by the Government that [Lopez]
    knowingly permitted the use of Las Carolina Ranch to store and
    transport marijuana past the Falfurrias border patrol checkpoint
    was the self-serving testimony of the “low-life” “boss” and self-
    professed “pothead” Jesus Carbajal and his crew of terminally high
    drug couriers who had each entered a guilty plea and given
    testimony against [Lopez] in hopes of receiving a more lenient
    sentence.
    Lopez argues that the Government only offered “assumptions stacked upon
    inferences and inferences stacked upon inferences,” and thus failed to prove he
    knew that Carbajal was actually transporting drugs through his ranch. In
    response, the Government argues that Lopez ignores the standard of review
    and fails to make the requisite credibility inferences in favor of the jury’s
    verdict.   The Government claims that the record provides “overwhelming
    evidence of Lopez’s guilt.”
    We hold that the district court did not plainly err in entering a guilty
    judgment because our review of the record demonstrates that there was more
    10
    Case: 13-40203     Document: 00512780393     Page: 11   Date Filed: 09/24/2014
    No. 13-40203
    than sufficient evidence of Lopez’s guilt.      Carbajal testified that Lopez
    approached him and offered to allow Carbajal to use his ranch to help transport
    the drugs past the border-patrol station. Carbajal also testified that Lopez
    arranged a meeting between the two of them and Garza, and that after that
    meeting, the smuggling business expanded significantly. The jury also heard
    testimony from a number of other witnesses describing Lopez’s involvement in
    the smuggling conspiracy. The coconspirators testified that they told Lopez
    they were going to drop marijuana off at his ranch, that Lopez was present
    during the loading and unloading of the marijuana, and that they witnessed
    Lopez and Carbajal meeting. Witnesses also told the jury that Lopez was
    present while loads of marijuana were being moved.            In addition, the
    Government presented evidence that Lopez ordered the construction of an
    outhouse on his ranch so that the smugglers could hide the marijuana they
    were transporting. Once law enforcement began to dismantle the conspiracy,
    Lopez then concealed the outhouse. Lopez was also paid for his part of the
    conspiracy.
    To counteract the weight of this testimony, Lopez points to his testimony
    at trial. He testified that he was a legitimate business man, who had been
    steadily employed his whole life. He also testified that he rented part of his
    ranch to Carbajal, and he thought Carbajal was moving barrels of hay. He
    denied ever talking to Carbajal about transporting drugs or being paid for
    drugs being stored on his ranch. But, it was the jury’s job to make credibility
    determinations, and on appeal, this Court makes all reasonable credibility
    choices in favor of the jury verdict. 
    Pierre, 958 F.2d at 1310
    –11.
    Considering all of this, the record was not devoid of evidence pointing to
    guilt, and so we affirm on this issue.
    11
    Case: 13-40203    Document: 00512780393      Page: 12   Date Filed: 09/24/2014
    No. 13-40203
    b. Zamora
    Zamora’s primary argument regarding the sufficiency of the evidence is
    that the testimony was uncorroborated. He claims that the Government tried
    to corroborate the witness testimony with the ATV and night-vision goggles
    that were used to smuggle drugs and were seized from Zamora’s home. But
    Zamora claims he did not own or control the ATV and that he did not use the
    night-vision goggles. Further, he argues that coconspirator testimony was
    incredible as a matter of law because the witnesses gave conflicting dates,
    ranging from 2005 to 2009, when testifying about when Zamora joined the
    conspiracy. The Government responds that Zamora’s arguments completely
    ignore the appropriate standard of review; applying the correct standard of
    review, the Government argues, the evidence is not plainly insufficient.
    We agree with the Government that the evidence supporting Zamora’s
    conviction was not plainly insufficient. First, Zamora’s arguments that the
    uncorroborated witness testimony is insufficient as a matter of law are
    unavailing. As discussed above, 
    see supra
    subpart III(B)(2), this Court has
    previously held that the Government is entitled to prove its case based on
    uncorroborated testimony from cooperating witnesses unless the testimony is
    incredible as a matter of law.    See 
    Villegas–Rodriguez, 171 F.3d at 228
    .
    Zamora does not otherwise attempt to argue that the testimony was incredible.
    Second, a review of the record shows that there was evidence to support
    the jury’s conviction. Zamora worked at Baluarte Ranch, and he secured jobs
    for Carbajal and other coconspirators to further the smuggling operation.
    Several witnesses testified that Zamora let them into Baluarte Ranch when
    they arrived with shipments. The jury also heard testimony that Zamora
    allowed other smugglers to store marijuana on the ranch or at his home. There
    was also testimony that Zamora was a law enforcement lookout and that
    Zamora personally transported loads off of Baluarte Ranch. Further, Zamora
    12
    Case: 13-40203   Document: 00512780393      Page: 13   Date Filed: 09/24/2014
    No. 13-40203
    was paid $1,000 per load, earning $30,000 to $40,000 for his work with
    Carbajal.
    Considering all of this testimony, we cannot say that the record is devoid
    of evidence to support the jury’s verdict. See 
    Delgado, 672 F.3d at 330
    –31.
    Thus, under plain-error review, the jury had sufficient evidence to find Zamora
    guilty.
    C.     Variance Between the Indictment and Evidence at Trial (Garza)
    At the outset, we note that Garza’s brief is somewhat inconsistent in how
    it frames this issue. Garza labels it a challenge to the sufficiency of the
    evidence in the headings of his brief. But, in the body of his brief, he discusses
    the factors this Court uses to determine whether there has been a variance
    between the indictment and proof at trial, and he then applies those factors to
    his case. Thus, despite the headings in his briefing, we will construe this as a
    variance argument.
    1. Standard of Review
    “The question whether the evidence establishes the existence of one
    conspiracy (as alleged in the indictment) or multiple conspiracies is a fact
    question within the jury’s province.” United States v. Mitchell, 
    484 F.3d 762
    ,
    769 (5th Cir. 2007). This Court affirms the jury’s finding of a single conspiracy
    “unless the evidence and all reasonable inferences, examined in the light most
    favorable to the government, would preclude reasonable jurors from finding a
    single conspiracy beyond a reasonable doubt.” 
    Id. (internal quotation
    marks
    omitted). Even when the Court finds a variance, the Court will “reverse only
    if the variance prejudiced the defendant’s substantial rights.”         
    Id. The defendant’s
    substantial rights are not affected “as long as the government
    establishes the defendant’s involvement in at least one of the proved
    conspiracies.” 
    Id. at 770.
    13
    Case: 13-40203     Document: 00512780393      Page: 14   Date Filed: 09/24/2014
    No. 13-40203
    2. Analysis
    “A material variance occurs ‘when the proof at trial depicts a scenario
    that differs materially from the scenario charged in the indictment but does
    not modify an essential element of the charged offense.’” 
    Id. at 769
    (quoting
    United States v. Delgado, 
    401 F.3d 290
    , 295 (5th Cir. 2005)). Determining
    whether there is a variance between the indictment, which charged a single
    conspiracy, and the proof at trial, which Garza alleges proved multiple
    conspiracies, requires counting the conspiracies. “The principal considerations
    in counting the number of conspiracies are (1) the existence of a common goal;
    (2) the nature of the scheme; and (3) the overlapping of the participants in the
    various dealings.” United States v. Morrow, 
    177 F.3d 272
    , 291 (5th Cir. 1999)
    (per curiam).
    Garza essentially argues that the Government only proved a series of
    smaller conspiracies instead of the single, overarching conspiracy charged in
    the indictment. He points out that Carbajal developed his smuggling scheme
    before Garza became involved with the conspiracy. Although he admits that
    several people used Carbajal’s system to transport marijuana from Mexico to
    the United States, Garza argues that there was not a single conspiracy because
    they were not sharing profits. The Government responds that everything
    Garza admits was sufficient for the jury to find a single conspiracy. Further,
    the Government argues that evidence clearly establishes a single conspiracy.
    After reviewing the evidence adduced at trial, we hold that there was not
    a material variance between the indictment and the proof at trial. Applying
    the relevant considerations here, the evidence was sufficient for reasonable
    jurors to find a single conspiracy beyond a reasonable doubt. This Court has
    previously defined having a “common goal” broadly, finding a common goal
    where “[t]he overall objective or goal was for everyone in the conspiracy to
    profit from the illicit purchase and selling of cocaine.” United States v. Morris,
    14
    Case: 13-40203     Document: 00512780393      Page: 15   Date Filed: 09/24/2014
    No. 13-40203
    
    46 F.3d 410
    , 415 (5th Cir. 1995); see also 
    Morrow, 177 F.3d at 291
    (describing
    the conspirators’ common goal as “deriv[ing] personal gain from the sale of
    mobile homes through the submission of false loan information”). Here, the
    jury could reasonably have found that the conspirators had a common goal of
    smuggling marijuana past the Falfurrias Border Patrol checkpoint for personal
    gain. Even Garza admits that all of the individuals involved were seeking their
    own profit from the illegal smuggling and sale of marijuana. While Garza
    emphasizes that the coconspirators were in competition with each other after
    smuggling the marijuana past the border, that fact does not preclude finding a
    common goal. United States v. Ross, 
    58 F.3d 154
    , 158 (5th Cir. 1995).
    Next, the nature of the scheme shows a single conspiracy. This Court
    has explained that, in examining the nature of the scheme, we do not look at
    charts or diagrams of wheels or chains in a conspiracy; instead, the Court
    conducts a “functional and substantive analysis.” 
    Morris, 46 F.3d at 415
    .
    “Where the activities of one aspect of the scheme are necessary or
    advantageous to the success of another aspect of the scheme or to the overall
    success of the venture, [or] where there are several parts inherent in a larger
    common plan . . . , the existence of a single conspiracy will be inferred.” United
    States v. Elam, 
    678 F.2d 1234
    , 1246 (5th Cir. 1982). Here, the coconspirators
    had coordinated drop-off times, and marijuana from different suppliers was
    stored and transported together. Viewed in the light most favorable to the
    verdict, this evidence shows that the several dealers who used Carbajal’s
    smuggling network were part of his larger common plan, reflecting a single
    conspiracy.
    Finally, the overlapping participants show a single conspiracy. “Where
    the memberships of two criminal endeavors overlap, a single conspiracy may
    be found. There is no requirement that every member must participate in
    every transaction to find a single conspiracy. Parties who knowingly
    15
    Case: 13-40203   Document: 00512780393     Page: 16   Date Filed: 09/24/2014
    No. 13-40203
    participate with core conspirators to achieve a common goal may be members
    of an overall conspiracy.” United States v. Richardson, 
    833 F.2d 1147
    , 1154
    (5th Cir. 1987). The evidence at trial established that Lopez introduced Garza
    to Carbajal at a meeting at Lopez’s ranch. After that meeting, Garza and his
    brother began moving marijuana through Carbajal’s smuggling system. Based
    on this testimony, the jury could reasonably have concluded that Garza was
    interacting with Carbajal, the core member of the conspiracy, to achieve the
    conspiracy’s common goal of smuggling marijuana past the border-patrol
    station for profit. Thus, we conclude that there was not a material variance
    because the proof at trial proved the single conspiracy charged in the
    indictment.
    D.     Brady Violation (Lopez)
    1. Standard of Review
    This Court “generally review[s] whether the government violated Brady
    de novo, although even when reviewing a Brady claim de novo, [the Court]
    must proceed with deference to the factual findings underlying the district
    court’s decision.” United States v. Brown, 
    650 F.3d 581
    , 589 (5th Cir. 2011)
    (citations and internal quotation marks omitted).
    2. Analysis
    “There are three components of a true Brady violation”: (1) the evidence
    at issue, whether exculpatory or impeaching, must be favorable to the accused;
    (2) “that evidence must have been suppressed by the State, either willfully or
    inadvertently”; and (3) “prejudice must have ensued.” Strickler v. Greene, 
    527 U.S. 263
    , 281–82 (1999). Evidence is material for purposes of Brady “if there
    is a reasonable probability that, had the evidence been disclosed to the defense,
    the result of the proceeding would have been different,” meaning the
    probability is “sufficient to undermine confidence in the outcome.” United
    States v. Bagley, 
    473 U.S. 667
    , 682 (1985) (internal quotation marks omitted).
    16
    Case: 13-40203     Document: 00512780393         Page: 17   Date Filed: 09/24/2014
    No. 13-40203
    Lopez argues that the Government violated Brady because it failed to
    disclose an exculpatory statement his ranch hand, Ruiz, made to the
    Government. Ruiz was arrested for being in the country illegally, and he told
    law enforcement agents that he had no knowledge of any illegal activity at
    Lopez’s ranch. After Ruiz made that statement but before the trial in this case,
    the Government sought to remove Ruiz from the country; Lopez agreed, and
    Ruiz was deported.       Lopez claims that he did not find out about Ruiz’s
    statement until trial; according to Lopez, the Government claimed it had
    complied with its Brady obligations and denied Ruiz had made any exculpatory
    statements. Lopez argues that this was material because, at trial, several
    witnesses pointed to Ruiz’s role in the conspiracy, and had Lopez been able to
    question Ruiz, he could have proven his innocence.                 In response, the
    Government urges us to decline to review this claim because Lopez failed to
    raise it before the district court.
    We decline to reach the merits of Lopez’s Brady claim because he failed
    to raise it before the district court. The question of what Lopez knew about
    Ruiz’s statement and when he knew it is the type of “fact-based judgment[]
    that cannot be adequately first made on appellate review [and] is why Brady
    challenges must be brought to the district court’s attention, winnowed by the
    trial judge, and made part of the record through a motion for a new trial.” See
    United States v. Rice, 
    607 F.3d 133
    , 142 (5th Cir. 2010) (citing United States v.
    Gonzales, 
    436 F.3d 560
    , 580 (5th Cir. 2006)). Here, it is not clear from the
    record whether Ruiz’s statement was actually suppressed.               At a pretrial
    conference, Lopez’s attorney stated, “[The prosecutor in Ruiz’s case] advised us
    at [the time of Ruiz’s expedited departure hearing] that [Ruiz] had given an
    exculpatory statement.” Lopez’s attorney then said that the agent to whom
    Ruiz made the statement “has forgotten about that statement or has denied
    that statement existed.” That same agent, however, testified to the statement
    17
    Case: 13-40203     Document: 00512780393     Page: 18   Date Filed: 09/24/2014
    No. 13-40203
    at trial, and Lopez never explains how we are supposed to reconcile the conflict
    between Lopez’s attorney’s statement in the pretrial conference and this
    testimony at trial. Thus, because it is impossible to determine whether the
    statement was suppressed based on the record before us, we hold that Lopez
    has waived this issue and decline to reach the merits of Lopez’s Brady claim.
    E.     Calculation of Guideline Ranges (Garza and Zamora)
    1. Standard of Review
    Under Gall v. United States, 
    552 U.S. 38
    (2007), appellate courts take a
    two-step approach in reviewing sentences. See 
    id. at 51.
    This Court will first
    review the sentence to ensure that it is procedurally sound and will then
    consider the substantive reasonableness of the sentence under an abuse of
    discretion standard. 
    Id. Nothing in
    this analysis, however, “purport[s] to alter
    [this Court’s] review of the district court’s construction of the Guidelines or
    findings of fact.” United States v. Cisneros–Gutierrez, 
    517 F.3d 751
    , 764 (5th
    Cir. 2008). Thus, this Court reviews factual findings related to sentencing for
    clear error: “[t]here is no clear error if the district court’s finding is plausible
    in light of the record as a whole.” 
    Id. (footnote and
    internal quotation marks
    omitted). The district court may find the “facts relevant to a defendant’s
    Sentencing Guidelines range by a preponderance of the evidence.” United
    States v. Harper, 
    448 F.3d 732
    , 735 & n.2 (5th Cir. 2006).
    Drug-quantity determinations are factual determinations. United States
    v. Ramirez, 
    271 F.3d 611
    , 612 (5th Cir. 2001). Whether a defendant is a
    minimal or minor participant is also a factual determination. United States v.
    Pofahl, 
    990 F.2d 1456
    , 1485 (5th Cir. 1993).
    2. Analysis
    a. Garza
    Garza argues the district court committed two errors in sentencing him.
    First, he claims the district court erred in calculating the drug quantity
    18
    Case: 13-40203    Document: 00512780393      Page: 19    Date Filed: 09/24/2014
    No. 13-40203
    attributable to him. Second, he argues that the district court erred in relying
    on a temporally distant crime—his 1994 marijuana-possession conviction —
    when calculating his criminal history. The Government responds that the
    record supports the district court’s finding that Garza is responsible for at least
    30,000 kg of marijuana.      The Government also argues that Fifth Circuit
    precedent forecloses Garza’s argument about the calculation of his criminal
    history.
    The drug quantity for sentencing purposes
    includes both drugs with which the defendant was directly
    involved, and drugs that can be attributed to the defendant in a
    conspiracy as part of his “relevant conduct” under § 1B1.3(a)(1)(B)
    of the Guidelines. Relevant conduct for conspiratorial activity is
    defined in § 1B1.3(a)(1)(B) as “all reasonably foreseeable acts and
    omissions of others in furtherance of jointly undertaken criminal
    activity.”
    United States v. Carreon, 
    11 F.3d 1225
    , 1230 (5th Cir. 1994) (citation omitted).
    “A district court may consider estimates of the quantity of drugs for sentencing
    purposes.” United States v. Cooper, 
    274 F.3d 230
    , 240 (5th Cir. 2001) (internal
    quotation marks omitted).       The PSR is considered reliable evidence for
    sentencing purposes. United States v. Clark, 
    139 F.3d 485
    , 490 (5th Cir. 1998)
    (per curiam). “The defendant bears the burden of showing that the information
    in the PSR relied on by the district court is materially untrue.” United States
    v. Valencia, 
    44 F.3d 269
    , 274 (5th Cir. 1995).
    We hold the district court did not clearly err in calculating the drug
    quantity used as the basis of Garza’s sentence.          First, some of Garza’s
    arguments rely on his contention that the evidence at trial only proved several
    smaller conspiracies, not a single conspiracy. But, we have already rejected
    Garza’s variance argument, 
    see supra
    subpart III(C), and a coconspirator can
    be held reasonable for all reasonably foreseeable relevant conduct.            See
    U.S.S.G. § 1B1.3(a)(1)(B). Garza does not appear to argue that the acts of other
    19
    Case: 13-40203     Document: 00512780393      Page: 20   Date Filed: 09/24/2014
    No. 13-40203
    suppliers were not foreseeable; he simply argues that they cannot be attributed
    to him because he was not part of the overarching conspiracy.
    Most importantly though, Garza’s arguments ignore the testimony that
    clearly linked Garza to more than 30,000 kg of marijuana. Ronny Rice, who
    worked as a driver for Garza and helped transport drugs across the border,
    testified that from 2005 to 2010, he carried two to five loads per week, with
    each load weighing 100 to 200 pounds. Even assuming the fewest loads at the
    lowest weight, this means Rice carried approximately 23,587 kg for Garza from
    2006 to 2010.     And, this does not include the more than 7,000 kg the
    Government seized from other members of the conspiracy—1,365 kg of which
    was found at Garza’s home. Garza has not offered any evidence to show that
    this information in the PSR is materially untrue. See 
    Valencia, 44 F.3d at 274
    .
    For these reasons, the district court did not err in calculating the drug quantity
    used as the basis of Garza’s sentence.
    Next, Garza argues that the district court erred when it used a
    “temporally remote conviction” to calculate his criminal history.             The
    Guidelines allow a district court to consider “any prior sentence of
    imprisonment exceeding one year and one month that was imposed within
    fifteen years of the defendant’s commencement of the instant offense.”
    U.S.S.G. § 4A1.2(e)(1). “So long as the defendant was incarcerated within the
    statutory time period, the prior sentence will be counted in the criminal history
    score—regardless of when the sentence was ‘imposed.’”           United States v.
    Arnold, 
    213 F.3d 894
    , 895–96 (5th Cir. 2000). Garza was released from prison
    for the marijuana offense in 1997. This is within fifteen years from when he
    commenced the conspiracy offense (2006). Garza himself acknowledges that
    Fifth Circuit case law forecloses this argument, and so the district court did
    not err in calculating his sentence. Thus, we affirm Garza’s sentence.
    20
    Case: 13-40203     Document: 00512780393     Page: 21   Date Filed: 09/24/2014
    No. 13-40203
    b. Zamora
    Zamora argues the district court committed three errors in calculating
    his sentence: (1) the district court erred in calculating the relevant drug
    quantity; (2) the district court erred in enhancing his sentence for firearm
    possession; and (3) the district erred when it failed to reduce his sentence
    because he was a minor participant. The Government responds that Zamora
    can be held responsible for all reasonably foreseeable conduct of his
    coconspirators. Given the scope of the conspiracy, the Government argues that
    it was reasonably foreseeable that more than 30,000 kilograms of marijuana
    would be smuggled into the United States. Further, the Government argues
    there was no error in giving Zamora the enhancement for possession of a
    firearm because Zamora had actual knowledge of the facts the district court
    used as the basis of the enhancement. Finally, the Government claims the
    district court correctly refused to give Zamora a minor-participant adjustment
    because Zamora played an important role in the conspiracy and was
    responsible for “[t]he most successful years” of the conspiracy.
    We conclude the district court did not err in calculating the drug quantity
    used as the basis for Zamora’s sentence. Zamora relies on Carreon to argue
    that the district court was required to make express findings of the amount of
    drugs attributable to him, based on his specific role in the conspiracy. But,
    Carreon is distinguishable from this case in several ways. First, in Carreon,
    the district court had attributed the entire quantity of drugs involved in the
    conspiracy to the defendant without any 
    explanation. 11 F.3d at 1231
    . Here,
    the PSR estimated the conspiracy was responsible for more than 100,000 kg of
    marijuana but used less than a third of that amount to calculate Zamora’s
    sentence. Cf. United States v. Fernandez, 
    559 F.3d 303
    , 323–24 (5th Cir. 2009)
    (affirming a sentence where the drug quantity attributed to the defendant was
    “hal[f] the drug amount attributed to the conspiracy as a whole”). Further, the
    21
    Case: 13-40203   Document: 00512780393      Page: 22   Date Filed: 09/24/2014
    No. 13-40203
    Court in Carreon specifically “rejected the proposition that a court must make
    a ‘catechismic regurgitation of each fact determined’; instead, [this Court]
    allowed the district court to make implicit findings by adopting the PSR.”
    
    Carreon, 11 F.3d at 1231
    . Here, the district court made this implicit finding.
    At the sentencing hearing, Zamora objected to the drug quantity, and the
    district court heard arguments from both parties before overruling the
    objection because Zamora was “responsible for the acts of that conspiracy.”
    Moreover, the evidence at trial also supports the district court’s estimate
    of the drug quantity attributable to Zamora. See 
    Fernandez, 559 F.3d at 323
    (affirming sentence where the evidence showed the defendant’s “knowledge of
    the breadth of the conspiracy”); United States v. Duncan, 
    191 F.3d 569
    , 575–
    76 (5th Cir. 1999) (affirming sentence where the “foundation for the findings
    in the PSR regarding the foreseeability of the drug quantities involved [was]
    manifestly apparent”). Mata testified that he and others transported loads to
    Baluarte Ranch as often as two to three times per week for three years and at
    least fifty times; he also testified that each load weighed between 350 and 450
    pounds. At the low end, this means 7,937 kg of marijuana were transported
    through Baluarte Ranch; at the high end, 95,526 kg of marijuana were
    smuggled through the ranch. Further, Carbajal specifically testified that the
    most successful years of the conspiracy were the years he worked with Zamora.
    As the PSR noted, several coconspirators identified Zamora as the person who
    helped them smuggle marijuana through Baluarte Ranch and scouted for law
    enforcement. Law enforcement officers also seized specific loads of marijuana
    on their way to Baluarte Ranch, with at least one load totaling more than 1,000
    kg.
    Finally and perhaps most importantly, Zamora bears the burden of
    showing that the information in the PSR was materially untrue. See 
    Valencia, 44 F.3d at 274
    . Zamora argues he did not start working at the Baluarte Ranch
    22
    Case: 13-40203     Document: 00512780393     Page: 23    Date Filed: 09/24/2014
    No. 13-40203
    until 2009, so he cannot be held responsible for any drugs smuggled before that
    date. But there was testimony at trial that Zamora joined the conspiracy as
    early as 2005 or 2006. Based on this testimony, it was plausible for the district
    court to conclude Zamora had been involved with the conspiracy for longer than
    he claimed, and thus was responsible for a greater quantity of drugs. In the
    absence of a more specific objection or additional evidence from Zamora
    showing that the information in the PSR was materially untrue, he has not
    met his burden of showing the district court erred in relying on the PSR. Thus,
    we hold the district court did not clearly err in finding Zamora responsible for
    30,000 kg of marijuana.
    We also affirm the enhancement for possession of a firearm. The PSR
    recommended the enhancement based on weapons that officers seized when
    they searched Zamora’s home. The district court concluded that the evidence
    was insufficient to show that those weapons were used in the offense, but still
    applied the enhancement because the evidence at trial showed Zamora carried
    a handgun. Zamora argues this was error; he claims he did not have proper
    notice because the enhancement was based on facts not in the PSR. But this
    Court has previously held that “if the defendant has actual knowledge of the
    facts on which the district court bases an enhancement or a denial of a
    reduction, the Sentencing Guidelines themselves provide” sufficient notice.
    United States v. Marmolejo, 
    89 F.3d 1185
    , 1201 (5th Cir. 1996) (internal
    quotation marks omitted). Zamora freely admits that he possessed a handgun,
    and he acknowledges Marmolejo forecloses this argument. Thus, the district
    court did not err in imposing the firearm enhancement.
    Finally, we also hold that the district court did not err in deciding not to
    award a minor-participant adjustment. Zamora argues he played only a minor
    role in the conspiracy, allowing drug runners access to the Baluarte Ranch and
    “perhaps, assist[ing] in unloading one of the shipments.” But, the evidence

    Case: 13-40203    Document: 00512780393    Page: 24   Date Filed: 09/24/2014
    No. 13-40203
    plausibly supported a more extensive role in the conspiracy, and Zamora
    ignores Carbajal’s testimony that “[t]he most successful years were when I
    started working [with Zamora] helping me out.” 
    See supra
    subpart III(B)(2)(b).
    Zamora’s involvement in the conspiracy was more than a single, isolated
    incident, and he was well-compensated for his work. See 
    Pofahl, 990 F.2d at 1485
    (affirming district court’s denial of a minor-participant reduction where
    defendant acted as a courier at least twice, recruited an individual to
    participate in the conspiracy, and received large payments for his work);
    United States v. Bethley, 
    973 F.2d 396
    , 401 (5th Cir. 1992) (“We have held that
    a ‘mule’ or transporter of drugs may not be entitled to minor or minimal
    status.”).   Thus, we conclude the district court did not err in sentencing
    Zamora.
    IV. CONCLUSION
    For the foregoing reasons, we AFFIRM.
