Chief Judge WALKER concurs in part and dissents in part in a separate opinion.
POOLER, Circuit Judge:The government appeals from the May 25, 1999, order of the United States District Court for the Southern District of New York (Shira A. Scheindlin, J.) granting the motion of defendant Gregory Ferguson for a new trial pursuant to Fed. R.Crim.P. 33. In addition, Ferguson cross-appeals the district court’s denial of his motion for judgment of acquittal pursuant to Fed.R.Crim.P. 29.
In this case, the district court exercised a rarely used power and granted a new trial to a defendant convicted of very serious crimes. We see no indication that the district court granted this relief lightly. While critics may consider a new trial for Ferguson to be a waste of resources and based on legal technicalities, we must take a broader view. No harm and only good can come to our system of justice where we require the government to supply competent, satisfactory and sufficient evidence to prove an element of criminal liability. To let a verdict stand on anything less is indeed a manifest injustice, and we share the district court’s concern that a defendant innocent of racketeering may nonetheless have been convicted of that crime.
*132BACKGROUND
Ferguson was one of 13 defendants that the government prosecuted in connection with its investigation of the Power Rules gang. According to the government, Power Rules operated on Union Avenue in the South Bronx between 1986 and 1997. The gang sold crack, powder cocaine and heroin. Power Rules members frequently used violence to facilitate their drug operations and increase their power through fear and intimidation, and they earned money performing contract murders. Miguel Guzman led the gang beginning in 1988. Gregory Ayala initially was a Power Rules member who worked a drug spot selling heroin and crack, but in late 1995 he began dealing directly with drug suppliers and formed his own gang, the Avenue St. John Boys. In late 1995 and early 1996, a war broke out between Power Rules and Avenue St. John Boys. According to the government, Guzman and his cohorts tried more than six times to shoot and kill Ayala. Many of these shootings took place in the streets, and the shootings often targeted Avenue St. John Boys members in addition to Ayala.
A federal grand jury returned an eighth superseding indictment on March 2, 1998, charging 13 defendants in 52 criminal counts stemming from their activities with Power Rules. The indictment charged Ferguson in eight counts with crimes including racketeering, conspiracy to violate racketeering laws, conspiracy to murder, attempted murder, use of firearms, and tampering with a witness and threatening court officers. The government characterized Ferguson as an enforcer for Power Rules who engaged in specific violent acts on its behalf. Specifically, counts 1 and 2 charged Ferguson and others with racketeering and conspiracy to racketeer, in violation of 18 U.S.C. §§ 1962(c) & 1962(d), respectively. Count 10 charged Ferguson and others with conspiracy to murder Ayala in aid of racketeering, in violation of 18 U.S.C. § 1959(a)(5). Count 11 charged Ferguson and Guzman with the attempted murder of Albert Mercado in aid of racketeering, in violation of 18 U.S.C. § 1959(a)(5). Counts 35 and 36 charged firearms offenses related to counts 10 and 11, respectively, in violation of 18 U.S.C. § 924(c). Count 51 charged Ferguson with witness tampering, in violation of 18 U.S.C. § 1512(b). Count 52 charged Ferguson with threatening deputy U.S. Marshals, in violation of 18 U.S.C. § 1503(a). The district court severed Count 52 prior to trial and ultimately dismissed it.
Trial of seven defendants, including Ferguson, took place between March 16, 1998, and June 12, 1998. During the trial, the government presented evidence that Ferguson and Power Rules members actively tried to kill rival gang leader Ayala. According to the government, on February 26, 1996, Ferguson and Power Rules members shot Albert Mercado, thinking he was Ayala. The government also tied Ferguson to two other incidents in which he and Power Rulés members searched for Ayala in his neighborhood with the intent to kill him but were unable to locate him. One incident involved hiring an “02” service car, and the other involved gang member David Rivera disguised in a Jamaican hat and fake dreadlocks. The government’s evidence connecting Ferguson to these incidents largely came from cooperating witnesses, including David Rivera. Cooperating witness Luis Soto, who acted as a double agent between Power Rules and Avenue St. John Boys, also testified that one or two weeks after the Mercado shooting, he saw Guzman give money to Ferguson.
The jury convicted Ferguson of two counts: conspiracy to murder Ayala in aid of racketeering (count 10) and using and *133carrying a firearm in connection with that offense (count 35), in violation of 18 U.S.C. §§ 1959(a)(5) and 924(c), respectively. The jury also convicted Guzman of 30 counts, convicted Edwin Rivera of 15 counts, and convicted Ayala of the four counts in which he was charged. We affirmed the convictions of these three defendants in a separate summary order. Of the remaining three trial defendants, the jury acquitted one and returned mixed verdicts regarding two others, who did not pursue direct appeals. Six of the 13 indicted defendants pleaded guilty after Judge Scheindlin granted a severance motion.
Ferguson made Rule 29 motions for judgment of acquittal at the close of the government’s case and at the end of trial. The district court reserved decision and ultimately denied the motions at a conference on June 18, 1998. Ferguson filed a motion for a new trial pursuant to Rule 33. The district court granted the motion in a written decision. See United States v. Ferguson, 49 F.Supp.2d 321 (S.D.N.Y. 1999). Ferguson was detained during trial, and he remains in detention. A panel of the Second Circuit vacated Judge Scheindlin’s bail order, and we extended that panel’s decision at the time of oral argument.
DISCUSSION
I. Standards of review
We review the decision of the district court to grant a new trial for abuse of discretion. See United States v. Scotti 47 F.3d 1237, 1241 (2d Cir.1995).1 Our review of Judge Scheindlin’s decision therefore is limited, and we are mindful that a judge has not abused her discretion simply because she has made a different decision than we would have made in the first instance. Indeed, it is on this simple yet critical matter that we find fault with the analysis of the dissent, which has chosen to review the trial evidence anew rather than apply the lens of abuse of discretion to Judge Scheindlin’s decision. Rather than engage in a debate with the dissent, we merely note, as we do throughout this opinion, that the district court’s holding is not an abuse of discretion even though we may have decided differently if we were the trial judge.
Just as our standard of review shapes our decision in this appeal, the standards that guide a trial court’s Rule 33 analysis shape its review of the trial evidence and the outcome of defendant’s Rule 33 motion. Rule 33 itself states that “the court may grant a new trial to [a] defendant if the interests of justice so require.” Fed.R.Crim.P. 33. The rule by its terms gives the trial court “broad discretion ... to set aside a jury verdict and order a new trial to avert a perceived miscarriage of justice.” United States v. Sanchez, 969 F.2d 1409, 1413 (2d Cir.1992). The district court must strike a balance between weighing the evidence and credibility of witnesses and not “wholly usurp[ing]” the role of the jury. Autuori 212 F.3d at 120. Because the courts generally must defer to the jury’s resolution of conflicting evidence and assessment of witness credibility, “[i]t is only where exceptional circumstances can be demonstrated that the trial judge may intrude upon the jury function of *134credibility assessment.” Sanchez, 969 F.2d at 1414. An example of exceptional circumstances is where testimony is “patently incredible or defies physical realities,” although the district court’s rejection of trial testimony by itself does not automatically permit Rule 33 relief. Id. '
The ultimate test on a Rule 33 motion is whether letting a guilty verdict stand would be a manifest injustice. See Sanchez, 969 F.2d at 1414. The trial court must be satisfied that “competent, satisfactory and sufficient evidence” in the record supports the jury verdict. Id. (internal quotation marks omitted). The district court must examine the entire case, take into account all facts and circumstances, and make an objective evaluation. See id. “There must be a real concern that an innocent person may have been convicted.” Id. Generally, the trial court has broader discretion to grant a new trial under Rule 33 than to grant a motion for acquittal under Rule 29, but it nonetheless must exercise the Rule 33 authority “sparingly” and in “the most extraordinary circumstances.” Sanchez, 969 F.2d at 1414. Judge Scheindlin properly cited these standards in her Rule 33 decision, and we see no indication that she failed to follow them in her analysis.
II. Grant of a new trial
The government argues that the district court abused its discretion in setting aside a jury verdict finding that Ferguson participated in the conspiracy to murder Ayala with a motive necessary to bring the crime within the scope of the racketeering statute. According to the government, the jury could have found beyond a reasonable doubt that Ferguson acted with any one of three motives: to gain entrance to the Power Rules enterprise, to increase or maintain his position in the Power Rules enterprise, or for pecuniary gain. Ferguson contends that the government abandoned the first two motive theories during the course of the trial and that the evidence concerning pecuniary gain was so slight as to be insufficient and incompetent. All three motives were in the indictment and jury charge.
A. Section 1959 standard
Section 1959 punishes defendants who commit violent crimes in aid of racketeering activity, and it contains a motive requirement. See 18 U.S.C. § 1959(a). Defendant’s motive must be receiving payment or promise of payment of anything of pecuniary value from the racketeering enterprise or “gaining entrance to or maintaining or increasing position” in the enterprise. Id. The scope of a pecuniary motive is fairly self-explanatory. With respect to the two other motives, “[s]elf-promotion need not have been the defendant’s only, or even his primary, concern, if [the criminal act] was committed ‘as an integral aspect of membership’ in the enterprise.” United States v. Thai 29 F.3d 785, 817 (2d Cir.1994) (quoting United States v. Concepcion, 983 F.2d 369, 381 (2d Cir.1992)). The government satisfies the motive requirement if “the jury could properly infer that the defendant committed his violent crime because he knew it was expected of him by reason of his membership in the enterprise or that he committed it in furtherance of that membership.” Concepcion, 983 F.2d at 381. Section 1959 reaches defendants associated with racketeering enterprises who may not be members but who participate in the organization’s activities with the aspiration of becoming members. See United States v. Polanco, 145 F.3d 536, 540 n. 2 (2d Cir.1998), cert. denied, 525 U.S. 1071, 119 S.Ct. 803, 142 L.Ed.2d 664 (1999); see also United States v. Malpeso, 115 F.3d 155, 159 n. 1, 164 (2d Cir.1997).
*135B. Membership motives
Judge Scheindlin held that during trial the government abandoned the motive theories of gaining entrance to Power Rules and increasing or maintaining position in the gang. See Ferguson, 49 F.Supp.2d at 325. The government argues that this finding was erroneous. Despite her abandonment finding, Judge Scheindlin went on to consider the evidence supporting the membership-related motives. For the purposes of this opinion, therefore, we will assume that the government did not waive these theories of criminal liability. Judge Scheindlin held that there was no credible evidence that Ferguson was a member of Power Rules or sought to become a member of Power Rules. Id. at 327-28. Based on the trial evidence, the district court held that “[a]t most, the jury found that Ferguson participated in two failed attempts to find and kill Ayala” and “[t]his does not rise to the level of activity necessary to support a finding of membership or a desire to become a member.” Id. at 328.
On appeal, the government argues that Ferguson was closely affiliated with Power Rules and acted with Power Rules members, using guns that gang leader Guzman supplied, to kill Ayala in order to protect the gang’s core drug business. According to the government, Ferguson’s motive was his affiliation with the gang “and his desire to maintain and enhance his close association with its leaders.” The district court did not abuse its discretion, however, when after it weighed the evidence, assessed witness credibility, and considered the jury’s verdict, it concluded that the membership motives fell short.
Many of the cases upon which the government relies show circumstances in which a defendant who is an established member of a criminal enterprise acts in a way consistent with that membership. See, e.g., United States v. Rahman, 189 F.3d 88, 126-27 (2d Cir.) (per curiam), cert. denied, 528 U.S. 982, 120 S.Ct. 439, 145 L.Ed.2d 344 (1999); United States v. Diaz, 176 F.3d 52, 94-95 (2d Cir.), cert. denied, 528 U.S. 875, 120 S.Ct. 181, 145 L.Ed.2d 153 (1999); Concepcion, 983 F.2d at 382-83. For example, Concepcion was a “lieutenant” in the enterprise and initiated violence in connection with its narcotics business to maintain and increase his leadership position in the group. See Concepcion, 983 F.2d at 382-83. In Diaz, defendants were gang members who furthered that membership by killing an informant who could harm the gang’s narcotics enterprise. See Diaz, 176 F.3d at 95. In this case, however, there was no direct evidence that Ferguson was a Power Rules member. The weight of the evidence showed that Ferguson was an outside hit man who did not belong to or seek to join Power Rules. Even the government so characterized Ferguson’s role. During summation, the prosecutor told the jury that Ferguson had “more limited involvement” in gang activities and “his role essentially was that of a hired gun.”
We recognize that evidence of a person’s membership in or association with a criminal enterprise may be circumstantial because Section 1959(b)(2) defines enterprise in part as a “group of individuals associated in fact.” 18 U.S.C. § 1959(b)(2). The government essentially relies on the same fact — Ferguson's participation in the effort to kill Ayala — to prove both his membership in Power Rules and his motive of furthering gang membership. According to the government, an important indication of Ferguson’s membership is that he acted with Power Rules gang members and followed the orders of gang leader Guzman. If this were a Rule 29 motion, we might agree with the government that the facts sufficiently showed membership and actions in furtherance of *136membership. However, the contrary view of the district court after weighing the evidence on a Rule 33 motion is not an abuse of discretion.
The government contends that the effort to murder Ayala not only was important to Power Rules but indeed was a core activity of the gang because killing a rival drug dealer was critical to protecting the gang’s principal activity of selling drugs. The government assigns error to the district court’s contrary holding and argues that Judge Scheindlin was wrong to discount all proof of the related Mercado shooting and consider only evidence of “two isolated occasions” of Ferguson’s participation in the conspiracy to murder Ayala. Ferguson, 49 F.Supp.2d at 327. What the district court held, however, was that the only gang activity in which Ferguson participated was the conspiracy to kill Ayala, and this conduct by itself was insufficient to show his membership in Power Rules. See id. at 327. Although she viewed evidence of the Mercado shooting as “suspect” in light of the jury’s acquittals on all counts related to this incident, see id. at 326 n. 8, Judge Scheindlin nonetheless examined the totality of the case as Sanchez requires. We cannot say that the district judge abused her discretion when she concluded that the weight of the evidence showed that Ferguson was an outside hit man and not a Power Rules member acting to further that membership. Ferguson may have participated in an important mission of Power Rules when he tried to kill Ayala, but that fact standing alone is not competent to show his racketeering motive.
While Ferguson need not have been a formal Power Rules member for criminal liability under Section 1959 to attach, there must be evidence that he acted with the expectation of gaining membership, see Polanco, 145 F.3d at 540 n. 2, see also Malpeso, 115 F.3d at 159 n. 1, 164, or in furtherance of an intimate involvement with the enterprise. See United States v. Muyet, 994 F.Supp. 501, 516 (S.D.N.Y.1998), aff'd, 225 F.3d 647 (2d Cir.2000). In order to show this sort of involvement, defendant must participate in the enterprise’s activities. See Malpeso, 115 F.3d at 159 n. 1. For example, in Muyet, a defendant who was not a member of the gang was closely associated with it and criminally liable under Section 1959 because he participated in high-level meetings with gang leaders or at gang headquarters, planned violent crimes to support the gang’s activities, and carried out crimes using his discretion. See Muyet, 994 F.Supp. at 516. Ferguson did not participate in Power Rules’ core activities of drug sales, extortion or robbery, and none of those additional circumstances is present with respect to Ferguson. Indeed, other than the facts of Ferguson’s participation in the Ayala murder conspiracy, the only trial evidence characterizing Ferguson as an associate of Power Rules rather than an outside hit man is the testimony of Luis Soto, who also defined an associate of Power Rules as a “friend of Miguel’s [Guzman].” Judge Scheindlin did not abuse her discretion on this Rule 33 motion by deciding that this evidence as a whole was incompetent.
C. Pecuniary gain motive
Judge Scheindlin also assessed the evidence supporting the pecuniary gain motive. On this issue, the government presented Luis Soto’s testimony that gang leader Guzman gave Ferguson a wad of bills one to two weeks after the Mercado shooting and in front of Power Rules gang members. Gang members and Ferguson shot Mercado, thinking he was Ayala. Even though the district court credited the Soto testimony, it found the evidence insufficient and incompetent to sustain Fer*137guson’s conviction because “Soto did not know the amount of the payment or its purpose” and “[n]o evidence was offered as to any discussions — preceding, contemporaneously, or after the payment — as to what the money was for.” Ferguson, 49 F.Supp.2d at 329. The government contends that the circumstances of the payment support the inference that the money was a payment for attempting to shoot Ayala. The government also argues that because Guzman paid other shooters, a jury could infer that the payment to Ferguson was for a shooting. However, the circumstances of the payment to Ferguson are equally consistent with an innocent purpose or even a criminal purpose unrelated to Ayala. In addition, the other instances in which Guzman paid shooters involved successful “hits.”
The district court did not abuse its discretion when it weighed the evidence of pecuniary motive and found the evidence unsatisfactory or insufficient to support the jury’s finding of guilt beyond a reasonable doubt. The district court properly relied on United, States v. Muyet, where we affirmed the Section 1959 conviction of “freelancer” Antonio Feliciano because there was evidence that he received a payment and that a witness overheard discussions connecting the payment to a violent crime. See Muyet, 994 F.Supp. at 519. That sort of connecting evidence is absolutely absent here and supports Judge Scheindlin’s conclusion that blind deference to the jury verdict is unwarranted.
D. Additional Rule 33 considerations
In her opinion, Judge Scheindlin cited additional considerations supporting her conclusion that a new trial is warranted. The district court noted a danger of prejudicial spillover from the RICO counts of which the jury acquitted Ferguson and the possible cumulative adverse effect of evidence of unproven charges. See Ferguson, 49 F.Supp.2d at 330. The district court even doubted its earlier decision refusing to sever Ferguson’s trial from that of his co-defendants. Id. Finally, the district court stated that it most likely should have used a special verdict form identifying which Section 1959 motive the jury found and the “fact that one was not used here supports the need for a new trial.” Id. at 324-25 n. 5. Because the district court did not abuse its discretion in granting a new trial based on incompetent motive evidence, we need not discuss these additional issues. In the event that the government pursues a new trial of Ferguson, he of course will not face trial on acquitted charges and he will be the sole defendant. Concerns about prejudicial spillover therefore are moot. With respect to the use of a special verdict form, that is a matter for the trial court’s discretion in managing a new trial. Similarly, because all three of the motive theories passed Rule 29 sufficiency scrutiny, the government is not precluded from pursuing any or all of them at a new trial.
III. Ferguson’s cross-appeal
The government filed its appeal of Judge Scheindlin’s order on June 7, 1999, pursuant to 18 U.S.C. § 3731. Ferguson did not appeal the district court’s denial of his Rule 29 motion directly, but in a document dated June 9,1999, defendant Ferguson filed a notice of cross-appeal purporting to raise the issue. Ferguson contends that Judge Scheindlin erred when she denied his Rule 29 motion, and he asks us to dismiss the indictment completely because the evidence supporting his convictions on counts 10 and 35 was insufficient. In his notice, defendant asserted pendent appellate jurisdiction. The government argues that we lack jurisdiction to hear the cross-appeal and that it is without merit. Because we agree that we lack jurisdiction to *138hear Ferguson’s cross-appeal, we do not consider it on the merits.
Putting aside the issue of whether Ferguson’s cross-appeal is timely pursuant to Fed. R.App. P. 4(b), we hold that he could not appeal Judge Scheindlin’s decision denying his motion for a judgment of acquittal. We have jurisdiction to consider appeals from final decisions of the district courts, which are judgments of conviction and sentence in criminal cases. See 28 U.S.C. § 1291; see also United States v. Aliotta, 199 F.3d 78, 81 (2d Cir.1999). When Judge Scheindlin ordered a new trial, she necessarily vacated Ferguson’s conviction from the first trial. Therefore, no judgment of conviction presently exists in this case. In addition, there is no pendent appellate jurisdiction in criminal cases. See Abney v. United States, 431 U.S. 651, 662-63, 97 S.Ct. 2034, 52 L.Ed.2d 651 (1977).
Ferguson is attempting to appeal a collateral order, but denial of a Rule 29 motion does not fall within the narrow scope of the collateral order doctrine, which requires an appealable interim order to “(1) conclusively determine the disputed question, (2) resolve an important issue completely separate from the merits of the action, and (3) be effectively unreviewable on appeal from a final judgment.” Aliotta, 199 F.3d at 81-82. Three kinds of orders fall within these parameters: pretrial motions to dismiss indictments on double jeopardy grounds, motions to reduce bail, and motions to dismiss under the Speech or Debate Clause. Id. at 82 & n. 2. Ferguson’s cross-appeal does not fall within any of these categories or meet any of the three criteria. Although at least two Second Circuit cases considered criminal appeals concerning non-final decisions, see United States v. Gerena, 869 F.2d 82, 83-84 (2d Cir.1989) (considering fair trial appeal because it overlapped appealable order concerning defendants’ privacy interests); see also United States v. Russotti, 717 F.2d 27, 31-32 & n. 2 (2d Cir.1983) (noting that defendant’s “subsidiary” claim of prosecutorial vindictiveness may not be proper basis for interlocutory appeal except to extent it relates to double jeopardy), the facts of those cases were sufficiently unique to distinguish them from the present case. Ferguson’s cross-appeal therefore is dismissed.
CONCLUSION
For the forgoing reasons, we affirm the order of the district court granting Ferguson a new trial pursuant to Rule 33. We also dismiss Ferguson’s cross-appeal as lacking appellate jurisdiction.
. The government suggests that a more stringent standard of review may be appropriate in Rule 33 cases involving a ruling that the verdict was against the weight of the trial evidence rather than a ruling that a jury instruction was erroneous, which was the case in Scotti. A change in circuit law is unwarranted. See United States v. Autuori, 212 F.3d 105, 120 (2d Cir.2000) (applying without discussion abuse of discretion standard to Rule 33 case concerning weight of the evidence).
