  •                                 UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    UNITED STATES OF AMERICA ex rel.
    FLOYD LANDIS,
    Plaintiff,
    v.                         Case No. 10-cv-00976 (CRC)
    TAILWIND SPORTS CORP., et al.,
    Defendants.
    MEMORANDUM OPINION AND ORDER
    Before the Court are several motions in limine from both parties. In this Memorandum
    Opinion and Order, the Court resolves the motions related to expert testimony: namely,
    Defendant Lance Armstrong’s motion to exclude the testimony of the Government’s three
    proposed experts (Larry Gerbrandt, Dr. Brian Till, and Dr. Jonathan Walker) (ECF No. 559) and
    the Government’s motions to exclude the testimony of Armstrong’s two experts, Douglas Kidder
    (ECF No. 557) and John Gleaves (ECF No. 558).1
    With respect to the Government’s experts, the Court will mostly deny Armstrong’s
    motion, but will grant it in two respects: (1) the experts cannot testify as to an impermissible
    theory of damages that has been previously rejected by the Court, namely that the fair market
    value of the promotional services that Armstrong’s cycling team rendered to the U.S. Postal
    Service (“USPS”) is zero, and (2) Gerbrandt cannot offer his unsubstantiated opinion that the
    harm resulting to the USPS from the negative publicity it received from coverage of Armstrong’s
    1
    In a separate Order issued today, the Court ruled on the parties’ other motions in limine.
    use of performance enhancing drugs (“PEDs”) necessarily outweighed the value of any benefits
    received from the sponsorship prior to revelations of Armstrong’s PED use.
    With respect to Armstrong’s experts, the Court will grant in part and deny in part both
    Government motions. The Court finds Mr. Kidder’s testimony admissible except insofar as it
    discusses the value of USPS’s cycling-themed Visa credit-card promotion. And the Court will
    permit Mr. Gleaves to testify as an expert witness with respect to the widespread nature of PED
    use in cycling, but will not permit him to testify to the other opinions laid out in his expert report.
    I.    Background
    A. Government’s Experts
    The Government intends to call three expert witnesses at trial to testify regarding its
    alleged damages: Larry Gerbrandt, Dr. Brian Till, and Dr. Jonathan Walker.

    Id. at 5.
    According to Armstrong and Dr.
    Gleaves’ expert report, he intends to testify about the history of the use of PEDs in cycling and to
    USPS’s awareness of Armstrong’s PED use and any failure to investigate that use. 
    Id. at 8–9;
    Armstrong’s Opp’n Pls.’ Mot. Exclude Gleaves Testimony (“Armstrong Gleaves Opp’n”) at 5–6.
    II.   Legal Background
    Rule 702 of the Federal Rules of Evidence permits the testimony of a witness as an expert
    if (1) the witness “is qualified as an expert by knowledge skill, experience, training, or
    education,” (2) the testimony “will help the trier of fact to understand the evidence or to
    determine a fact in issue,” (3) the testimony is “based on sufficient facts or data,” (4) the
    testimony “is the product of reliable principles and methods,” and (5) the expert has “reliably
    applied the principles and methods to the facts of the case.” Fed. R. Evid. 702.
    If a witness is deemed to be qualified to testify as an expert, the Court then applies the
    two-part test laid out in Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
    (1993), to
    determine if the remaining requirements for admissibility under Rule 702 are met. Under
    Daubert, the Court must determine “whether the expert is proposing to testify to (1) scientific
    knowledge that (2) will assist the trier of fact to understand or determine a fact in issue.” 
    Id. at 592.
    In other words, the proffered expert testimony “must be both reliable and relevant.” United
    States v. Nwoye, 
    824 F.3d 1129
    , 1136 (D.C. Cir. 2016).
    5
    In determining reliability, the Court’s purpose is to conduct a “preliminary assessment of
    whether the reasoning or methodology underlying the testimony is scientifically valid and of
    whether that reasoning or methodology properly can be applied to the facts in issue,” an analysis
    focused “solely on principles and methodology, not on the conclusions that they generate.”
    
    Daubert, 509 U.S. at 592
    –93, 595. The Supreme Court in Daubert identified four factors to
    consider in this analysis: “(1) whether the theory or technique can be and has been tested; (2)
    whether the theory or technique has been subjected to peer review and publication; (3) the
    method’s known or potential rate of error; and (4) whether the theory or technique finds general
    acceptance in the relevant scientific community.” Ambrosini v. Labarraque, 
    101 F.3d 129
    , 134
    (D.C. Cir. 1996) (citing 
    Daubert, 509 U.S. at 593
    –94). Ultimately, this inquiry is a “flexible
    one” and “none of the factors discussed is necessarily applicable in every case or dispositive; nor
    are the four factors exhaustive.” 
    Id. (quoting Daubert,
    509 U.S. at 594).
    In addition to reliability, the proposed testimony must also meet the second prong of
    Daubert: relevance. This requires the Court to determine “whether the proffered expert
    testimony ‘is sufficiently tied to the facts of the case that it will aid the jury in resolving a factual
    dispute.’” 
    Id. (quoting Daubert,
    509 U.S. at 591). The proponent of the expert testimony bears
    the burden of showing, by a preponderance of the evidence, that these requirements for
    admittance are met. See 
    Daubert, 509 U.S. at 592
    n.10.
    III. Analysis
    A. Armstrong’s Motion (Government’s Experts)
    Armstrong broadly challenges all three of the Government’s expert witness on the ground
    that their testimony is not relevant. He also raises specific challenges to the qualifications or
    reliability of the experts individually. The Court will address each issue in turn.
    6
    1. Relevance
    Armstrong challenges all three of the Government’s experts’ proposed testimony on the
    ground that it will not help the trier of fact to understand the evidence or determine a fact in
    issue. First, he argues the testimony is not relevant insofar as the experts are attempting to prove
    an impermissible theory of damages. Second, he argues the testimony is irrelevant because it
    will lead the jury to improperly speculate as to the amount of damages. The Court concludes that
    Armstrong is correct that the Government is seeking to prove damages under an impermissible
    theory and will prohibit the expert testimony insofar as it relates to that theory; however, the
    Government’s proffered expert testimony is still relevant to a permissible, non-speculative theory
    of damages and thus, aside from any other ground for exclusion, is admissible.
    a. Impermissible Theory of Damages
    Armstrong first challenges certain aspects of the testimony of the Government’s experts
    as irrelevant because it relates to an impermissible theory of damages. Specifically, he argues
    that testimony from Gerbrandt and Dr. Walker that the cycling-team sponsorship had no fair
    market value is inadmissible because it attempts to prove damages via a theory that the Court
    prohibited at summary judgment. Armstrong MIL at 18, 35. The Government responds that the
    Court’s summary judgment ruling did not “foreclos[e] the jury from considering the market
    value of the tainted services, and ultimately concluding that market value is ascertainable.” Pls.’
    Opp’n at 4.
    As discussed in more detail in the Court’s opinion on summary judgment, the relevant
    standard for damages in this case is that laid out by the D.C. Circuit’s decision in United States
    v. Science Applications International Corp. (“SAIC”), 
    626 F.3d 1257
    (D.C. Cir. 2010). The
    Court at summary judgment explained that “[t]he market value of the cycling team’s ‘PED-
    7
    tainted’ promotional services is just as ‘impossible to determine’” as the services rendered in
    SAIC. United States ex rel. Landis v. Tailwind Sports Corp., 
    234 F. Supp. 3d 180
    , 200 (D.D.C.
    2017). However, the Court held, the Government “may attempt to prove that the positive
    benefits of the sponsorship were reduced—or even eliminated altogether—by the negative
    publicity that accompanied the subsequent investigation and disclosure of Armstrong’s doping.”
    
    Id. at 201.
    The Court’s decision on summary judgment has foreclosed the Government from
    arguing, as it seeks to do now, that the fair market value of the services rendered—promotional
    services from an undisclosed tainted team—was zero. This is so because, as the Court held, the
    fair market value of that service is not readily ascertainable. See 
    id. at 200–01;
    cf. 
    SAIC, 626 F.3d at 1279
    (concluding that services by entity with undisclosed conflicts was not readily
    ascertainable). To the extent that the Government’s proffered experts intend to testify to that
    theory of damages, their testimony is irrelevant and inadmissible. But to the extent that the
    Government seeks to prove that the negative impact of the publicity surrounding the disclosure
    of Armstrong’s doping and concealment thereof outweighed any positive benefits received prior,
    the testimony of the experts is relevant and, if all other conditions are met, admissible. Cf.
    
    Landis, 234 F. Supp. 3d at 204
    (indicating the expert testimony at issue here is relevant to a
    proper theory of damages).
    b. Speculative Testimony on Damages
    Armstrong further argues that even if the Government’s experts intend to testify as to the
    permissible theory of damages here, their testimony is still irrelevant because they fail to provide
    a sufficiently concrete means by which the jury can calculate damages. He claims that “the
    government seeks to have the jury do what its experts did not—quantify the amount of damages
    8
    without any ability to do so, any method for doing so, or any evidence of its amount.”
    Armstrong’s Reply in Supp. of Mot. Exclude Testimony of Gerbrandt, Till, and Walker 5; see
    also Armstrong MIL at 16–17, 32. The Government responds that damages are not speculative
    simply because there is uncertainty as to the amount when, as here, there is certainty as to injury.
    Pls.’ Opp’n at 6–8.
    The rule on a plaintiff’s required proof of damages was laid out by the Supreme Court in
    Story Parchment Co. v. Paterson Parchment Co., 
    282 U.S. 555
    (1931). See, e.g., Hill v. Republic
    of Iraq, 
    328 F.3d 680
    , 684 (D.C. Cir. 2003) (explaining that Story Parchment “states the
    American rule on damages”). There, the Supreme Court stated that:
    Where the tort itself is of such a nature as to preclude the ascertainment of the
    amount of damages with certainty, it would be a perversion of fundamental
    principles of justice to deny all relief to the injured person, and thereby relieve the
    wrongdoer from making any amend for his acts. In such case, while the damages
    may not be determined by mere speculation or guess, it will be enough if the
    evidence show the extent of the damages as a matter of just and reasonable
    inference, although the result be only approximate.
    Story 
    Parchment, 282 U.S. at 563
    . In other words, “while a plaintiff seeking to recover . . . must
    ordinarily prove the fact of injury with reasonable certainty, proof of the amount of damages may
    be based on a reasonable estimate.” Samaritan Inns, Inc. v. District of Columbia, 
    114 F.3d 1227
    ,
    1235 (D.C. Cir. 1997). Essentially, this boils down to a requirement that there be “some
    reasonable basis on which to estimate damages.” 
    Hill, 328 F.3d at 684
    (quoting Wood v. Day,
    
    859 F.2d 1490
    , 1493 (D.C. Cir. 1988)).
    Moreover, when considering whether damages are too speculative, courts “make
    allowances for the fact that the defendants’ own misconduct has foreclosed any exact calculation
    of” damages. United States ex rel. Miller v. Bill Harbert Int’l Const., Inc., 
    608 F.3d 871
    , 905
    (D.C. Cir. 2010). As the Supreme Court has stated, “where the defendant by his own wrong has
    prevented a more precise computation, the jury may not render a verdict based on speculation or
    9
    guesswork” but it “may make a just and reasonable estimate of the damage based on relevant
    data.” Bigelow v. RKO Radio Pictures, 
    327 U.S. 251
    , 264 (1946). So it is here: As the Court
    has previously noted, the quantification of damages in this case is “a task no doubt made difficult
    by the delay in public awareness of Armstrong’s doping caused by his concealment.” 
    Landis, 234 F. Supp. 3d at 204
    .
    In cases where calculation of the exact measure of damages is not possible with
    mathematical certainty, the D.C. Circuit has approved of theories of damages that involve expert
    witnesses testifying to methods a jury can use to estimate damages. For instance, in Miller, the
    D.C. Circuit affirmed a damages award in a False Claims Act case involving allegations that the
    defendant had rigged a contract bid, resulting in an inflated price for a government 
    contract. 608 F.3d at 905
    –07. The court highlighted two of the government’s damages theories: first, an expert
    testified as to a typical profit margin in this type of contract and the government argued that the
    jury should use actual costs plus that profit margin to estimate the government’s losses; and
    second, the government proposed the jury estimate a competitive bid award using one of two
    benchmark numbers, including one based on other bid proposals. 
    Id. at 905–06.
    The D.C.
    Circuit concluded that both of these were permissible methods to estimate damages. 
    Id. Similarly, in
    Tri County Industries, Inc. v. District of Columbia, 
    200 F.3d 836
    (D.C. Cir.
    2000), the D.C. Circuit reversed the district court’s determination that the award of lost profits
    stemming from the defendant’s failure to approve a building permit was too speculative and
    remote. 
    Id. at 842.
    The plaintiff had presented testimony from several witnesses that discussed
    projections about the planned facility’s output and costs. 
    Id. at 841.
    In addition, an expert
    witness testified to the general market for the planned facility, offered “a comparison of service
    rates for similar operations,” and “projected the profitability of Tri County’s facility.” 
    Id. The 10
    D.C. Circuit concluded that in light of this testimony, the award for lost profits was “sufficiently
    well-founded to avoid characterization as ‘mere speculation or guess.’” 
    Id. at 842
    (citation
    omitted); see also United States v. Sci. Applications Int’l Corp., 
    958 F. Supp. 2d 53
    , 77–78
    (D.D.C. 2013) (holding evidence of damages was not speculative where three witnesses provided
    non-speculative testimony based on personal experience that the services rendered had less value
    than what the government paid for them).
    As in Miller and Tri County, the testimony that the Government intends to offer here
    provides grounds beyond “mere speculation or guess” for the jury to calculate an award of
    damages. Indeed, the Court suggested at summary judgment that the testimony of the experts
    discussed here was relevant to determining damages. See 
    Landis, 234 F. Supp. 3d at 204
    . The
    Government has indicated that Dr. Till will testify “that there is a general causal relationship
    between negative publicity about a sponsored celebrity-athlete and diminished consumer
    perception of a sponsoring brand.” Pls.’ Opp’n at 24. In turn, Gerbrandt will testify “that there
    was a great deal of negative publicity.” 
    Id. And finally,
    Dr. Walker will “estimate the harm to
    USPS from public disclosure of Armstrong’s PED use.” 
    Id. at 31.
    In tandem, these three experts
    provide the jury a framework on which to estimate an amount of damages: the linkage of USPS
    with negative coverage of Armstrong’s doping scandal (Gerbrandt) led to a negative impact on
    USPS’s brand (Till), which resulted in an estimated loss amount (Walker). Each witness’s
    testimony here is based on more than mere speculation and is relevant to prove the government’s
    damages in a non-speculative way.
    Armstrong’s argument throughout his motion appears to assume that this Court should
    consider each expert witness as walled off from the others when determining relevance, and
    faults the government for the fact that Till and Gerbrandt will not provide numerical estimates of
    11
    the damages claimed. Armstrong MIL at 18–19, 32. But Armstrong provides no reason why the
    fact that any single expert, alone, might not fully prove the pathway to damages means that the
    Court should not look to whether the government can rely on all three working together. Rather,
    “i[t] is well established that a court may not exclude an expert’s otherwise reliable and relevant
    testimony simply because, without more, the testimony is insufficient to prove a proponent’s
    entire case.” Rothe Dev. Inc. v. Dep’t of Def., 
    107 F. Supp. 3d 183
    , 198 (D.D.C. 2015); see also
    Adams v. Ameritech Servs., Inc., 
    231 F.3d 414
    , 425 (7th Cir. 2000) (“[T]he question before us is
    not whether the [expert] reports proffered by the plaintiffs prove the entire case . . . . No one
    piece of evidence has to prove every element of the plaintiffs’ case . . . .”). Each expert’s
    testimony has a tendency to make the Government’s damages more probable, and together they
    provide a non-speculative framework for the jury to use to analyze damages.
    In sum, the three experts that the Government intends to introduce together provide the
    jury a sufficiently non-speculative framework for determining damages. That those damages
    might be somewhat uncertain does not justify excluding the testimony of the experts as too
    speculative or leading the jury to improperly speculate on damages. Thus, their testimony is
    relevant, provided the experts adhere to the damages framework adopted by the Court in its
    summary judgment ruling.
    2. Challenges to Gerbrandt
    Moving to Armstrong’s specific challenges to each of the Government’s experts, the
    Court begins with Mr. Gerbrandt.
    a. Qualifications
    Armstrong first challenges Gerbrandt’s qualifications to testify as an expert, contending
    12
    that he is not qualified to opine on any harm to USPS.2 He contends that since Gerbrandt has no
    academic training or publications in the field of negative publicity valuation, he is not qualified
    to testify about negative media impressions resulting from Armstrong’s PED use.
    For a witness to testify as an expert, he must be qualified based on “knowledge, skill,
    experience, training, or education.” Fed. R. Evid. 702. Thus, the absence of formal academic
    training or a degree is not fatal to a witness’s status as an expert; experience, knowledge, or skill
    can also suffice to show qualifications. Gerbrandt has more than thirty years of experience as a
    media and entertainment analyst, including prior experience as an expert witness analyzing the
    economics and value of television programming and advertising. Gerbrandt Expert Report at 3–
    4. He has published reports on the value of media and advertising, including three Nielsen
    reports on the impact of new technology on media consumption and advertising pricing and
    expenditures. Pls.’ Opp’n Ex. 1 (“Gerbrandt Decl.”) ¶ 4. In light of Gerbrandt’s experience in
    media and entertainment analysis—both of which are relevant to a discussion of the number of
    media impressions viewers receive—the Court concludes he is qualified to testify as to media
    coverage of Armstrong’s PED use and any associated links to USPS.
    b. Failure to Apply Reliable Methodology
    Armstrong further contends that Gerbrandt’s testimony is inadmissible because it is not
    the product of reliable scientific methods or principles. He challenges two particular aspects of
    2
    Armstrong also argues that Gerbrandt is not qualified to address valuation reports
    commissioned by USPS from two marketing firms, Campbell Ewald and FCB. Armstrong MIL
    at 19. Given that the Court has held the reports are inadmissible, Gerbrandt likely will not be
    opining on the reports. See Pls.’ Opp’n at 14. As such, this issue is likely moot. To the extent
    that there is still a possibility that the Government might ask Gerbrandt about the reports at trial,
    the Court will reserve any challenges to his qualifications in this regard until then.
    13
    Gerbrandt’s testimony: (1) his conclusion that negative publicity harmed USPS, and (2) his
    media-impression count.
    As for the first issue, Armstrong argues that Gerbrandt’s conclusion that USPS was
    harmed by any negative publicity of Armstrong’s PED use is not based on any underlying
    science or methodology. Gerbrandt’s expert report does conclude that “the harm to USPS
    resulting from such a large volume of negative impressions would necessarily outweigh the
    value of any benefits received by USPS resulting from positive impressions during the
    sponsorship period.” Gerbrandt Expert Report at 6. Yet the bulk of Gerbrandt’s analysis is
    dedicated to calculating the number of negative impressions linking Armstrong, his PED use,
    and USPS. 
    Id. at 21–49.
    His expert report simply states that the number of negative impressions
    necessarily outweighs any positive impressions. But nowhere does Gerbrandt discuss the
    positive impressions that USPS derived from its sponsorship, how the positive impressions
    compare with the negative impressions, or (alternatively) why he need not calculate positive
    impressions. As a result, the Court is unsure as to how Gerbrandt determined that the negative
    impressions outweighed the positive impressions, let alone necessarily so. While Gerbrandt is
    free to opine that USPS was harmed by the negative publicity and about the extent of that
    publicity, he cannot testify that the negative impressions outweighed the positive impressions
    without setting forth a foundation for that opinion, which his report does not do.
    Second, Armstrong contends that Gerbrandt’s media-impression count is not the product
    of a reliable methodology. He faults Gerbrandt for “fail[ing] to rely on any methodology” in
    determining how many media impressions linked negative coverage of Armstrong’s PED use
    and USPS. Armstrong MIL at 14. But Gerbrandt’s expert report reveals a method to his
    calculations. He consulted the “premiere independent sources for marketing, advertising, public
    14
    relations, Internet and social media and entertainment decisions and purchases” such as Nielsen
    Co. (which tracks television ratings) and Cision (which tracks editorial coverage). Gerbrandt
    Expert Report at 25. He examined these sources, surveyed them for media that connected
    Armstrong with PED use and that mentioned or referenced USPS in some fashion, and gathered
    information on the “reach” of these sources, i.e., the number of viewers. See 
    id. at 26–49.
    Based
    on this research, Gerbrandt totaled the “media impressions” from the individual media types and
    sources. 
    Id. at 50.
    Armstrong complains that Gerbrandt “merely states that his 41,912 Internet articles
    translate into 154.4 billion impressions . . . but provides no meaningful explanation for how he
    made those calculations.” Armstrong MIL at 14. But Gerbrandt’s expert report states that, for
    Internet articles, he consulted Cision database—which archives traditional print and digital
    media—with “a series of search terms . . . connecting Mr. Armstrong with the use of
    performance enhancing drugs and blood doping.” Gebrandt Expert Report at 27. The search
    was additionally “constrained to only those news items and articles that specifically mentioned
    or identified the USPS in some fashion.” 
    Id. Cision also
    provided the “reach” of each article,
    which is simply “the unique visitors per month to the website on which the article is posted” for
    an online article. 
    Id. Based on
    this information, Gerbrandt was able to calculate the “media
    impressions” by summing the number of articles multiplied by the reach of each article. 
    Id. Clearly, Gerbrandt
    did provide an explanation of the method he used in reaching the total
    impressions for Internet articles and the other forms of media in his report. See generally 
    id. at 26–49.
    His process has an underlying methodology that is sound and reasonable.
    Armstrong’s criticisms of this method—such as that impressions may be different
    lengths, or that different media has different advantages and disadvantages—are the sort that go
    15
    to the weight to give Gerbrandt’s testimony, not its admissibility. See 
    Ambrosini, 101 F.3d at 140
    (“[E]fforts to discredit [an expert’s] methodology by pointing to the limits of the research he
    undertook . . . goes to the weight rather than the admissibility of his testimony.”). The Court
    concludes that Gerbrandt’s conclusions on the media-impression count are based on a reliable
    methodology and therefore admissible.
    3. Challenges to Dr. Till
    To recap, the Government has offered Dr. Till to testify that negative press coverage of
    Armstrong harmed consumers’ impressions of USPS. Armstrong argues that Till’s conclusions
    should be excluded because they are not the product of reliable principles and methods. He
    contends that because Till failed to conduct any particular tests or research on the facts of this
    case, his conclusions are not the product of a reliable methodology and he has failed to apply any
    principles or methods to the facts of this case. The Court disagrees.3
    For one, Till’s general theory of causation—that negative publicity regarding a sponsor
    athlete tarnishes the brands the athlete has promoted—has been subject to testing, publication,
    and peer review, and appears to enjoy some degree of acceptance in the academic community.
    Till himself published an article in a peer-reviewed journal detailing the results of a study
    indicating that negative information about an endorser is likely to have a negative impact on the
    associated brand. See Brian D. Till & Terrence A. Shrimp, Endorsers in Advertising: The Case
    of Negative Celebrity Information, 27 J. ADVERT. 67 (1998). His expert report indicates that
    other scholars in the field have also published articles showing that a sponsor’s negative
    information can have a negative impact on the associated brand as well. See Till Expert Report
    3
    Armstrong does not challenge Dr. Till’s qualifications.
    16
    at 3. As such, the general theory of causation to which Till intends to testify is the product of
    reliable scientific methods.4
    Armstrong further contends that Till’s testimony is inappropriate because he has not
    conducted a specific study on the facts of this case that shows any negative impact on the USPS
    brand. This argument also misses the mark. Courts frequently allow the testimony of expert
    witnesses as to general academic or scientific principles, including general theories of causation.
    See, e.g., 
    Ambrosini, 101 F.3d at 135
    –36 (holding that medical expert’s testimony that a drug
    was generally capable of causing the plaintiff’s injury in a product liability case was relevant);
    Miller v. Holzmann, 
    563 F. Supp. 2d 54
    , 96 (D.D.C. 2008) (permitting expert witness to testify
    to general economic principles related to bid-rigging), aff’d in relevant part, 
    Miller, 608 F.3d at 895
    . To the extent that Till’s testimony is intended to show “that there is a general causal
    relationship between negative publicity about a sponsored celebrity-athlete and diminished
    consumer perception of a sponsoring brand,” Pls.’ Opp’n at 24, his failure to perform a specific
    study on the facts of this particular case does not undermine the reliability of his method—
    relying as it does on a published, peer-reviewed study he previously performed and other
    academic literature in his field corroborating that study’s results.
    And to the extent that Till intends to testify about the likelihood that his general theory of
    causation applies in this case, his failure to perform a specific study here is still not fatal. Till’s
    4
    The case is thus distinguishable from Frosty Treats, Inc. v. Sony Computer
    Entertainment America, Inc., No. 03-cv-378, 
    2004 WL 5500100
    (W.D. Mo. Mar. 3, 2004),
    where Dr. Till’s testimony was excluded. There, Dr. Till’s theory on “reciprocal spillover
    effects” “ha[d] not been subjected to peer review or publication” and “appear[ed] to have been
    developed for use in litigation.” 
    Id. at *3.
    In contrast, Dr. Till’s general theory of negative brand
    association has been subject to testing as well as peer review and publication and there is no
    indication he developed his theory—which was published in a 1998 journal article—for use in
    litigation in this case or any other.
    17
    report indicates that he reviewed facts and details about this case and applied principles
    developed from academic literature to those facts. See Till Expert Report at 1, 4–5. Armstrong
    provides no reason to believe that this is not a reliable method for an academic in Till’s field. He
    essentially argues that Till should have conducted his own study specifically on Armstrong’s
    PED use, but the fact that Till did not perform the study that Armstrong wanted or use the
    method Armstrong desired to reach his conclusion does not make the method he did use
    unreliable.
    Finally, Armstrong contends that Till’s testimony is unreliable because he did not rely on
    a survey conducted regarding the impact of Armstrong’s PED use on the USPS brand and failed
    to consider relevant factors in determining whether a brand is damaged by a sponsor’s negative
    publicity. But such “efforts to discredit [Till’s] methodology by pointing to the limits of the
    research he undertook . . . goes to the weight rather than the admissibility of his testimony.”
    
    Ambrosini, 101 F.3d at 140
    . Armstrong remains free to raise these issues before the jury on
    cross-examination and to argue that the jury should give Till’s testimony less weight. But these
    contentions do not necessarily render his testimony unreliable. The Court will therefore allow
    Till’s testimony as long as he refrains from discussing the prohibited theory of damages, as
    discussed above.
    4. Challenges to Dr. Walker
    Armstrong next turns to Dr. Walker, who, again, intends to testify about the potential
    monetary impact of the negative coverage of Armstrong’s PED use on the USPS. Armstrong
    argues that Walker’s testimony should be excluded because his methodology is “composed
    18
    entirely of speculation” and therefore not reliable or reliably applied to the facts of the case.
    Armstrong MIL at 36–37.5
    The Court disagrees. Armstrong’s argument primarily faults Walker for not running an
    event study to quantify the financial impact of the negative coverage on USPS in particular.
    However, Walker could not run an event study specific to USPS because an event study can only
    be performed on a publicly traded company: an event study “measure[s] the effect that [an] event
    had on the stock price of publicly traded companies impacted by [an] event.” Till Expert Report
    at 18 (emphasis added); see also Pls.’ Opp’n at 30. Instead, Walker looked at event studies
    performed on publicly traded companies that had experienced a similar event to USPS, namely
    the revelation that a sponsor was engaged in a scandal. Till Expert Report at 20–22. For
    instance, Walker looked at event studies that calculated the impact of the Tiger Woods scandal
    on his associated brands. 
    Id. at 22.
    Walker then used the results of these event studies to approximate the financial impact of
    Armstrong’s PED use on USPS. 
    Id. at 24.
    Because USPS is not publicly traded and has no
    stock values, Walker applied the calculated losses from the other event studies to stock values for
    similar companies, namely other parcel delivery services with annual revenue similar to USPS.
    
    Id. at 23.
    Based on his application of the event-study-calculated loss rates to the similarly-sized
    parcel companies, Walker estimated a range of possible financial loss to USPS from the scandal.
    
    Id. at 32.
    In light of the analysis that he performed, Walker’s ultimate conclusion is not based on
    rank speculation. Armstrong does not dispute that event studies are a reliable methodology used
    5
    Armstrong does not challenge the qualifications of Dr. Walker.
    19
    by experts in Walker’s field. Given the impossibility of performing an event study on USPS
    itself, see 
    id. at 31–32,
    it seems reasonable to use the results of event studies conducted in similar
    circumstances to estimate a possible range of losses for USPS. The Court therefore concludes
    that Walker’s testimony is sufficiently reliable to be admissible, again so long as Walker adheres
    to the Court’s limitations as to a permissible theory of damages.
    B. Government’s Motions (Armstrong’s Experts)
    The Court now turns to the Government’s objections to Armstrong’s proposed experts,
    beginning with Douglas Kidder, who plans to testify regarding economic benefits USPS derived
    from the cycling sponsorship.
    1. Challenges to Douglas Kidder
    a. Qualifications
    At the outset, the Government argues that Kidder is unqualified to testify as an expert
    because he lacks formal training in business, economics, or finance, and because he has no
    particular experience in valuing media exposure. The Court, however, does not find that these
    claimed deficiencies demand excluding Kidder’s testimony. Again, witnesses may be qualified
    as experts based on their practical experience. See Fed. R. Evid. 702 advisory committee’s note
    to 2000 amendment. Courts regularly allow witnesses with general experience in business
    valuation to provide expert testimony about the value of a specific asset, even where the witness
    has no particularized expertise on assets of that type. See, e.g., Popovich v. Sony Music Entm’t,
    Inc., 
    508 F.3d 348
    , 359 (6th Cir. 2007) (witness’s experience with business valuation allowed
    him to testify about value of company’s contract right to affix logo to album); cf. Coleman v.
    Parkline Corp., 
    844 F.2d 863
    , 866 (D.C. Cir. 1988) (witness’s experience with investigating
    industrial accidents allowed him to testify about danger of elevator ceiling). So while Kidder has
    20
    no formal education in economics or finance, his 25-plus years of experience valuing businesses,
    including 13 years advising businesses on whether to acquire “new business interests,” Kidder
    Depo. at 14:22–15:10, establish that he is qualified to testify about the economic value of
    sponsoring a cycling team.
    b. Failure to Apply Reliable Methodology in Expert Report
    The Government also contends that Kidder should be barred from testifying about the
    economic benefits USPS received from sponsorship because of flaws in his methodology. The
    Government challenges Kidder’s reliability on a slew of grounds, which can be summarized as
    follows: (1) Kidder’s estimate of USPS sales revenue generated by the cycling sponsorship
    improperly ignores the costs of those new sales; (2) his conclusions about sales revenue and
    earned media revenue simply adopt USPS data without any interpretation; and (3) his
    conclusions about new sales and earned media revenue are unduly speculative. With one small
    exception, the Court disagrees with the Government’s contentions and will allow Kidder to
    testify as an expert about the conclusions contained in his expert report.
    First, the fact that Kidder’s expert report does not expressly consider costs associated
    with USPS’s increased sales does not warrant excluding his testimony. To be sure, the Court’s
    summary judgment ruling explained that the relevant “measure of benefits received by the Postal
    Service would be net income from the sales in question, not gross revenue.” Landis, 234 F.
    Supp. 3d at 202. USPS’s costs are therefore relevant to the issue of damages. But so long as
    Kidder does not mislead the jury—for example, by suggesting without further explanation or
    support that USPS had no costs associated with its new sales—he is permitted to testify about a
    single variable (gross revenue) of the damages equation (gross revenue minus costs). Cf. Rothe
    
    Dev., 107 F. Supp. 3d at 198
    (“[A] court may not exclude an expert’s otherwise reliable and
    21
    relevant testimony simply because, without more, the testimony is insufficient to prove a
    proponent’s entire case.”). Kidder’s report does not hide the ball on this point: it indicates that
    he will testify about “$374 million in quantifiable gross benefits,” Kidder Report at 4 (emphasis
    added). And Armstrong makes a reasonable argument that the marginal costs of USPS’s
    increased sales are negligible because, according to USPS’s own analysis, the costs associated
    with USPS’s marketing operations were primarily fixed, not variable. See Def.’s Opp. at 8–9;
    see also Kidder Depo. at 219:15–220:9 (Kidder explaining his consideration of USPS’s costs). If
    the Government disagrees, it is free to put on evidence of costs (beyond the sponsorship fee)
    associated with that gross revenue.
    Second, the Court finds no problem with Kidder’s reliance on USPS sales data in forming
    his conclusions. Experts regularly rely on parties’ sales data when valuing assets. See, e.g.,
    Ward v. Dixie Nat’l Life Ins. Co., 
    595 F.3d 164
    , 181–82 (4th Cir. 2010) (upholding admission of
    expert testimony on damages that relied in large part on spreadsheets created by defendants).
    And Kidder’s reliance on USPS’s data here makes common sense: USPS calculated these sales
    figures in evaluating whether to extend the cycling sponsorship, and thus had an incentive to
    accurately estimate new sales attributable to the sponsorship. Moreover, Kidder is not, as the
    Government contends, merely parroting USPS figures without any use of his expertise. As
    discussed below, several years of USPS sales data are unavailable, and Kidder has estimated
    sales for those years using extrapolation and interpolation from sales figures for surrounding
    years. And, more generally, Kidder’s collation, explanation, and summation of USPS’s figures
    strikes the Court as the sort of analysis “customarily relied upon in his industry for the valuation
    of assets, a subject beyond the experience of most jurors.” Elliott v. Kiesewetter, 112 F. App’x
    821, 824 (3d Cir. 2004). The approach may not be especially complex, but it is not so obvious as
    22
    to render it an inappropriate basis for expert testimony. See 
    Ward, 595 F.3d at 181
    (expert
    “applied an appropriate interest rate” to parties’ data in estimating damages).
    Third, for the most part, the Court does not find that Kidder’s conclusions about sales
    revenue or earned media are unduly speculative. Contrary to the Government’s argument,
    Kidder has provided a reliable method of filling in gaps in sales and earned-media figures. In
    estimating the value of new sales for 2001–2004, where USPS data was not available, Kidder
    extrapolated from data for 2000, which he deemed a “conservative” method of filling the gaps
    because evidence in the record suggests that sales attributable to the sponsorship increased for
    each year of the sponsorship. Kidder Report at 9. Similarly, in estimating the value of earned
    media, Kidder interpolated data for 1998–2000, which USPS did not track, using figures for
    1997 and 2001. 
    Id. at 15.
    He also relied on estimates of domestic earned media exposure to
    estimate the value of international media exposure in certain years, citing an advertising agency
    report commissioned by USPS stating that the latter dominated the former. 
    Id. at 13–14.
    While
    the Government contends that Kidder’s uses of interpolation and extrapolation rendered his
    estimates too speculative, the Court finds that Kidder’s resulting estimates are sufficiently
    reliable to allow introduction of his testimony at trial, where the Government will be free to
    argue that the estimates should be accorded little weight.
    Nor does the Court believe that Kidder’s testimony is based on impermissible speculation
    as to the link between USPS’s new sales and earned media, on one hand, and the cycling
    sponsorship, on the other. The Government identifies purported flaws in Kidder’s approach—for
    example, that he improperly assumes that USPS’s planned sales for 2000 materialized into actual
    sales. Pls.’ Kidder MIL at 10. These limited criticisms do not require exclusion of Kidder’s
    testimony, and can instead be directed toward undermining Kidder’s conclusions at trial. See
    23
    
    Ambrosini, 101 F.3d at 140
    . Similarly, while the Court in a separate Order issued today ruled
    that advertising reports produced by Campbell Ewald and FCB are not themselves admissible,
    Kidder is permitted to rely on those reports in estimating the value of earned revenue attributable
    to the sponsorship. See Fed. R. Evid. 703 (allowing expert to rely on inadmissible facts or data
    in forming opinions so long as experts in that field would reasonably do so). After all, the
    reports were commissioned by USPS, and in internal correspondence USPS cited figures from
    the reports with approval. See 
    Landis, 234 F. Supp. 3d at 203
    ; Kidder Report at 6–7.
    The Court does, however, find that one portion of Kidder’s planned testimony is not
    rooted in a sufficiently reliable methodology. In estimating new sales attributable to the cycling
    sponsorship, Kidder counted revenues from USPS’s cycling-themed Visa credit card promotion.
    Kidder Report at 9–11. This promotion, which USPS ran in 2000, encouraged customers to use
    Visa cards when purchasing USPS goods by entering Visa users into a sweepstakes for cycling-
    themed prizes, including a trip to the Tour de France. 
    Id. at 10.
    Kidder cites USPS data
    suggesting that the promotion generated $39.8 million in new revenue based on increased sales
    and decreased transaction costs associated with credit-card purchases. 
    Id. But unlike
    with the
    figures that Kidder relies on to estimate postage and shipping sales generated by the cycling
    sponsorship, and unlike his use of the advertising reports to estimate earned-media revenue,
    Kidder’s expert report does not provide a reasonable basis for linking revenues generated by the
    Visa promotion to USPS’s sponsorship of the cycling team.
    Again, USPS entered the cycling sponsorship with the goal of generating new sales
    contracts and gaining media exposure. As Kidder plans to testify, USPS attempted to quantify
    those benefits in order to justify the cost of the sponsorship, which provides a reasonable basis
    for attributing those benefits to the sponsorship itself. Not so with the Visa promotion, which
    24
    appears to have been an entirely separate promotional agreement. And Kidder’s report lays no
    independent foundation for attributing revenues from the Visa promotion to the sponsorship of
    Armstrong’s team. Rather, as the Government contends, a cycling-themed promotion might
    have generated just as much revenue absent a cycling sponsorship—customers would be enticed
    by the prizes even without a prior association between USPS and cycling. In opposing the
    motion to exclude Kidder’s testimony, Armstrong does not respond to the Government’s
    contention on this front. The Court will therefore exclude testimony about revenue from the
    Visa promotion. Kidder may, however, testify as to the other conclusions contained in his expert
    report.
    c. Failure to Apply Reliable Methodology in Rebuttal Report
    Finally, the Court finds that Kidder may testify as an expert about the conclusions stated
    in his rebuttal report, which seek to undermine the conclusions of the Government’s expert, Dr.
    Walker. The report does not, as the Government argues, contain impermissible legal
    conclusions. Kidder’s testimony that Walker’s opinion is “irrelevant,” for example, does not
    appear to be statement about legal relevance, but rather is a criticism of Walker’s approach as
    rooted in inapposite anecdotes.6 See Gov.’s MIL Ex. 2 (Kidder Rebuttal), at 7–8. Nor is
    Kidder’s general approach unreliable. In responding to Walker’s conclusion that Armstrong’s
    PED scandal eliminated his value as an endorser, Kidder cites competing scandals that
    undermine Walker’s assertion. In responding to Walker’s conclusion about the value of the 2000
    sponsorship agreement, Kidder points out temporal concerns with Walker’s analysis. And in
    responding to Walker’s use of an event study to estimate USPS’s losses caused by the PED
    6
    The Court will, of course, ensure that at trial neither party’s expert is permitted to offer
    bare legal conclusions.
    25
    scandal, Kidder explains why, in his view, event studies are useless for businesses without stock
    prices. The Court finds that, with each of these responses, Kidder relies on a sufficiently
    reliable methodology rooted in his business-valuation expertise, and that he is permitted to
    provide his rebuttal testimony under Rule 702.
    2. Challenges to Dr. John Gleaves
    The Government also challenges the testimony of Dr. Gleaves. Armstrong, in reply,
    contends that Gleaves is primarily offered as a summary witness. The Government indicated in a
    footnote that it has reserved any challenges to Gleaves’ proffered summary testimony under Rule
    1006 and that the appropriate time to address those challenges is in the Joint Pretrial Statement.
    As such, the Court will solely address the Government’s challenges to Gleaves’ expert testimony
    and will reserve judgment on any summary witness testimony (and the admissibility of any
    summary evidence) until then.
    According to Armstrong and Gleaves’ expert report, Gleaves intends to offer three
    opinions: (1) that PED use was widespread in cycling; (2) that USPS knew or should have
    known about Armstrong’s PED use; and (3) that USPS failed to investigate any suspected PED
    use. The Court will admit testimony concerning Gleaves’ first opinion but will exclude
    testimony on the latter two points.
    a. Dr. Gleaves’ Conclusion About PED Use in Cycling
    The Government first challenges Gleaves’ attempt to testify as an expert witness
    concerning the widespread nature of PED use in cycling.7 Primarily, the Government argues that
    7
    The Government does not challenge Dr. Gleaves’s qualifications with respect to this
    opinion.
    26
    any PED use by non-USPS riders is not relevant. Armstrong counters that this evidence is
    relevant to three issues: (1) materiality, (2) causation, and (3) Armstrong’s statute of limitations
    defense.
    The Court will start with Armstrong’s statute of limitations defense. The key question
    for this defense is when the government “knew or should have known” the “facts material to the
    right of action.” See 28 U.S.C. § 2416(c) (tolling provision for non-False Claims Act claims); 31
    U.S.C. § 3731(b)(2) (tolling provision for False Claims Act claims).8 The widespread use of
    PEDs by non-USPS riders around the time of the Government’s sponsorship agreement raises a
    possible inference that the Government suspected PED use by its own riders and further helps
    illuminate whether the Government’s actions with respect to investigating any suspected PED
    use were reasonable. As such, it is relevant to Armstrong’s statute of limitations defense. The
    Court concludes, therefore, that Dr. Gleaves’ opinion on the widespread nature of PED in
    cycling is relevant to an issue in the case, namely the statute of limitations defense.
    For similar reasons, the Court concludes that Dr. Gleaves’ opinion on the widespread
    nature of PED use in cycling is also relevant to materiality. Under the False Claims Act, “[a]
    misrepresentation about compliance with a statutory, regulatory, or contractual requirement must
    8
    At this juncture, the Court need not address the appropriate legal framework for
    Armstrong’s statute of limitations defense, such as the level of notice required or which officials
    (i.e., those at USPS or those at the Department of Justice) were required to have this notice.
    However, the Court will remind the parties that per its prior opinion addressing this topic, the
    statute of limitations “does not commence upon notice of allegations of impropriety instead, it is
    when the impropriety itself is known or reasonably should have been known by the relevant
    official that” it commences. United States ex rel. Landis v. Tailwind Sports Corp., 
    51 F. Supp. 3d
    9, 40 (D.D.C. 2014). Therefore, USPS’s knowledge of allegations of PED use or of PED use
    by other non-USPS riders is by itself insufficient to trigger the statute of limitations; rather “it
    must be a finding of the doping—not an investigation seeking to determine whether doping
    occurred—that is a ‘fact material’ to the government’s [] claims.” 
    Id. 27 be
    material to the Government’s payment decision in order to be actionable.” Universal Health
    Servs., Inc. v. United States ex rel. Escobar, 
    136 S. Ct. 1989
    , 1996 (2016) (emphasis added).
    The statute defines “material” as “having a natural tendency to influence, or be capable of
    influencing, the payment or receipt of money or property.” 31 U.S.C. § 3729(b)(4). Thus,
    materiality “look[s] to the effect on the likely or actual behavior of the recipient of the alleged
    misrepresentation.” Universal 
    Health, 136 S. Ct. at 2002
    (citation omitted) (alteration in
    original).
    Armstrong argues that the evidence of PED-use by non-USPS riders is relevant to
    materiality, and the Court agrees. As noted above, the widespread nature of PED use in cycling
    creates a possible inference that the USPS suspected Armstrong’s own PED use. A decision by
    the USPS to enter into a sponsorship agreement with Armstrong while aware of or suspecting his
    PED use could create a further possible inference that Armstrong’s possible PED use did not
    influence the USPS’s payment decisions—in other words, that his PED use was not material to
    the Government’s payment decision. Alternatively, the endemic nature of PED use in cycling
    creates a possible inference that the Government was aware of the widespread use of PEDs.
    That, combined with a failure by the Government to take steps to investigate any potential
    doping by Armstrong before entering into a sponsorship agreement, would similarly raise a
    possible inference that the USPS did not particularly care about any PED use by Armstrong—
    again, yielding an inference that PED use was not material to the Government’s funding
    decisions. Given these permissible chains of possible inferences, the widespread nature of PED
    use is relevant to materiality.
    The Court does not find, however, that the widespread nature of PED use is relevant to
    causation: that is, whether Armstrong caused the team to dope and submit false claims. While
    28
    evidence that USPS team members used PEDs before Armstrong joined might be relevant to
    determining Armstrong’s role in the team’s PED use, the actions of non-USPS members shed no
    real light on the actions of USPS team members—that everybody else was using PEDs says
    nothing about Armstrong’s role in causing false claims to be presented to the Government. As
    such, the evidence is not admissible as to causation.
    As to the Government’s argument that Gleaves’ opinion is too vague to be helpful to the
    jury, such arguments go to the weight, rather than admissibility, of the testimony. See
    
    Ambrosini, 101 F.3d at 140
    . Finally, the Court disagrees with the Government’s contention that
    because the jury could make some analysis of the widespread nature of PED use, Gleaves’
    argument is inadmissible. In light of Gleaves’ academic background, expertise, and familiarity
    with this area of study, see Gleaves Expert Report at 3–6, his testimony will still be helpful and
    relevant. The Court will thus allow Gleaves to testify as to his opinions concerning the
    widespread nature of PED use in cycling.
    Before moving on, however, the Court will briefly address the temporal nature of
    Gleaves’ proposed testimony. Gleaves apparently intends to opine at length on the history of
    PED use in cycling dating back to 1890. See, e.g., Gleaves Expert Report at 69. But what is
    most relevant in his testimony is any opinion concerning the widespread nature of PED use in
    cycling contemporaneous with USPS’s sponsorship of the cycling team. While Gleaves’ opinion
    that PED use has always been widespread, 
    id. at 69–79,
    may be relevant to what the Government
    knew or should have known in 2003, it has much less probative value compared to his opinions
    concerning contemporaneous PED use. Additionally, allowing Gleaves to testify at length on the
    history of PED use in cycling since 1890 runs a significant risk of creating undue delay or
    wasting time as well as of prejudice to the Government in the form of the argument that because
    29
    everyone was using PEDs, Armstrong should not be held accountable if he has violated the False
    Claims Act. See Pls.’ Gleaves MIL at 10. As such, the Court will permit limited discussion of
    the use of PEDs in cycling during periods of time not contemporaneous with the Government’s
    sponsorship and subsequent developments and will restrict Gleaves’ testimony to solely that
    which is admissible under Rule 403. See Fed. R. Evid. 403 (excluding relevant evidence if the
    probative value is substantially outweighed by a danger of unfair prejudice, undue delay, or
    wasting time).
    b. Dr. Gleaves’ Other Opinions
    The Government further challenges Gleaves’ remaining two opinions—which concern
    what USPS employees knew and their failure to investigate PED use—as not based on a reliable
    methodology, not helpful to the jury, and an improper usurpation of the jury’s role in
    determining credibility and findings of fact.
    The Court agrees that this part of Gleaves’ testimony should be excluded. Gleaves’
    methodology for reaching his conclusions as to what USPS officials knew (or should have
    known) appears to consist entirely of reading the deposition transcripts of USPS employees and
    summarizing what they said. In Gleaves’ expert report, his summary of his opinions on this
    point cites almost exclusively to USPS employee deposition testimony. See Gleaves Expert
    Report at 79–88. And during his own deposition, Gleaves described his method as simply that:
    reviewing the deposition testimony of USPS employees and—to determine if their memories
    were accurate—comparing it to other public source materials. See, e.g., Pls.’ Gleaves MIL Ex. 2
    at 171:2–8 (Q: “What is your basis for saying that Ms. Sonnenberg in fact knew that cyclists on
    the USPS team were—were using performance-enhancing substances?” A: “I read her testimony
    . . . . That’s my basis.”).
    30
    This testimony is problematic for at least two reasons. For one, expert testimony
    typically must concern something beyond the ken of the average juror. See, e.g., United States v.
    Boney, 
    977 F.2d 624
    , 629 (D.C. Cir. 1992) (“[Expert] testimony should ordinarily not extend to
    matters within the knowledge of laymen.”). But the average juror is entirely capable of
    reviewing the testimony of USPS witnesses and drawing conclusions as to what they knew—or
    should have known—or did concerning Armstrong’s PED use. See United States v. Mitchell, 
    49 F.3d 769
    , 780 (D.C. Cir. 1995) (holding that district court did not err in precluding expert
    testimony on tape recorded conversations because “elucidat[ing] tape recorded conventions” is a
    “matter[] of general knowledge”).
    In fact, it is precisely the jury’s function to review the testimony of witnesses and
    determine what factual conclusions to draw from that testimony; courts have long recognized
    that “determining the weight and credibility of [a witness’s] testimony” is a duty that “belongs to
    the jury, who are presumed to be fitted for it by their natural intelligence and their practical
    knowledge of men and the ways of men.” Aetna Life Ins. Co. v. Ward, 
    140 U.S. 76
    , 88 (1891).
    As such, Gleaves’ testimony regarding his second and third opinions “not only involves matters
    of general knowledge, but is squarely within the traditional province of the jury” and is therefore
    inappropriate expert witness testimony. 
    Mitchell, 49 F.3d at 780
    ; see also United States v.
    Johnson, 
    54 F.3d 1150
    , 1157–58 (4th Cir. 1995) (holding that testimony involving a chart that
    simply summarized other witnesses’ testimony and that the proffered expert did not use any
    “specialized knowledge” to prepare was not admissible expert testimony).
    Armstrong suggests that it is a common practice for historians to look to materials such
    as recorded recollections and public source materials to determine what a person knew at a point
    in time. While this may be true, it is irrelevant here. All of the USPS employees that Gleaves
    31
    would testify about can (and likely will) be called as a witness and asked in front of the jury,
    point blank, what they knew or did and when they knew or did it. And Armstrong is free to
    probe each employee’s knowledge or to try to call the employee’s statements into question
    during examination as permitted by the rules of evidence. The jury is more than capable of
    drawing its own conclusion as to what any particular USPS employee knew (or should have
    known) and did at the relevant time period without any assistance from an expert witness, based
    on any testimony at trial and the other evidence.
    Moreover, Gleaves’ testimony would veer dangerously close to offering an expert
    opinion on the credibility of a witness, which is impermissible. See, e.g., Nimely v. City of New
    York, 
    414 F.3d 381
    , 398 (2d Cir. 2005) (“[T]his court, echoed by our sister circuits, has
    consistently held that expert opinions that constitute evaluations of witness credibility, even
    when such evaluations are rooted in scientific or technical expertise, are inadmissible under Rule
    702.”); United States v. Samara, 
    643 F.2d 701
    , 705 (10th Cir. 1981) (“An expert ‘may not go so
    far as to usurp the exclusive function of the jury to weigh the evidence and determine
    credibility.’” (citation omitted)). Gleaves’ methodology of comparing the USPS testimony to
    publicly available sources and offering his conclusion as to what the USPS employees knew
    essentially amounts to an argument that that employee and potential witness at trial was telling
    the truth or lying about her knowledge. This testimony is thus an attack on likely witnesses’
    credibility and is inadmissible for this reason as well.
    IV. Conclusion
    For the foregoing reasons, it is hereby
    ORDERED that [559] Defendant Armstrong’s Motion to Exclude Testimony of Larry
    Gerbrandt, Brian Till, and Jonathan Walker is GRANTED IN PART and DENIED IN PART.
    32
    None of the experts will be permitted to testify to the prohibited theory of damages. In addition,
    Gerbrandt cannot offer his opinion that the negative impressions necessarily outweighed any
    positive impressions from the sponsorship. Aside from these two limitations, the testimony of
    Gerbrandt, Dr. Walker, and Dr. Till is admissible. It is further
    ORDERED that [557] the Government’s Motion to Exclude Testimony of Dr. Douglas
    Kidder is GRANTED IN PART and DENIED IN PART. Kidder’s testimony is admissible
    except insofar as it discusses the value of the Visa credit card promotion. It is further
    ORDERED that [558] the Government’s Motion to Exclude Testimony of Dr. John
    Gleaves is GRANTED IN PART and DENIED IN PART. The Court will permit Dr. Gleaves to
    testify concerning his opinion that the use of PEDs was widespread in cycling, but will not
    permit him to testify as to the other opinions set forth in his expert report.
    SO ORDERED.
