            Per Curiam.             Defendants Andrea, Michael, and John R.

Lentz,   individually             and   d/b/a        L&L    Collisions,    appeal        civil

judgments       entered       upon      jury    verdicts       concluding        that     they

participated in an automobile insurance fraud scheme which damaged

plaintiff Metropolitan Property & Casualty Company and violated,

inter alia, the Racketeering Influenced and Corrupt Organizations

("RICO") Act.         See 18 U.S.C. §§ 1962, 1964.                 Defendants argue that,

due to a nearly complete absence of evidence that the United States

mails    were     used       in    furtherance         of    the     scheme,     there     was

insufficient evidence from which the jury could have found the

predicate acts of mail fraud -- the theory under which the RICO

claim went to the jury -- and, derivatively, insufficient evidence

from which the jury could have found that the alleged acts of mail

fraud    constituted          a      "pattern"         of    racketeering        activity.1

Proceeding       on    the    assumption        that       their    principal     appellate

argument    is    meritorious,          defendants          further    contend    that     the

evidence relevant to the RICO counts (which defendants say the jury

never should have heard) was so prejudicial that it might well have

misled the jury into holding them liable under non-RICO theories.

             Our review of the record reveals that defendants did not



     1
      Defendants also hint at other theories why there was
insufficient evidence to support the jury's "pattern" finding, but
those theories fail because, in addition to being only minimally
developed on appeal, they were not presented with sufficient
specificity to the district court before the jury was discharged.
See infra.

                                               -2-
present either their principal appellate argument, or the "pattern"

argument which is largely built from it, see n.1, above, to the

district court with sufficient specificity to have made their

position on the matter understood until after the jury verdicts

were returned.     We will not disturb a lower court's judgment on the

basis of an argument raised so late in the game unless the argument

persuades us that, among other things, a miscarriage of justice has

occurred.    See Davignon v. Clemmey, 

, 13 (1st Cir. 2003)

(argument first presented in a post-verdict Fed. R. Civ. P. 50

motion is forfeited); Blockel v. J.C. Penney Co., Inc., 

, 25 (1st Cir. 2003) (sufficiency arguments must be made with

specificity to preserve them for plenary appellate review); Rivera-

Torres v. Ortiz Velez, 

, at *14 (1st Cir. Aug. 26,

2003)   ("claims   forfeit[ed]   through   ignorance   or   neglect"   are

subject to plain error review, which permits error correction in

civil cases only when the error "resulted in a miscarriage of

justice or seriously affected the fairness, integrity, or public

reputation    of   judicial   proceedings")   (citations    and   internal

quotation marks omitted).      There was no miscarriage of justice in

this case.    Rather than demonstrating or strongly suggesting that

no mailings took place in furtherance of the scheme, the record is

merely ambiguous about which documents were mailed and which were

hand delivered.      An ambiguity of this sort does not call into

question the fundamental fairness of the trial.             To vacate or


                                   -3-
reverse the judgments on the basis of an issue that only came into

focus after the jury was discharged could encourage sandbagging in

future cases with little in the way of present benefits.

          Defendants'     remaining    appellate    argument    regarding

prejudicial   spillover   depends     upon   our   agreeing    with   their

principal argument. Because we have rejected defendants' principal

argument, we reject defendants' remaining argument without further

discussion.

          Affirmed.
