In this ERISA case, a former NFL player, Dwight Harrison, sues to challenge the plan administrator’s denial of certain retirement benefits. The district court granted summary judgment in favor of the administrator, holding that the claim was barred by collateral estoppel and that, in the alternative, the administrator did not abuse its discretion,'under ERISA, in denying benefits. The court also denied a request to grant relief under Federal Rule of Civil Procedure 60(b) regarding a previous suit by Harrison.

We have reviewed the briefs, the applicable law, and pertinent portions of the record and have heard the helpful arguments of counsel. There is no reversible error, so the judgment is AFFIRMED, essentially for the reasons convincingly stated by the district court in its impressive twenty-five-page opinion.
