The league hasn't come up with any kind of catchy nickname for the Sept. 4 season opener between the New York Jets and Washington Redskins. But if NFL officials want a moniker for that Thursday night prime-time matchup, which officially kicks off the 2003 season, we've got a suggestion.

The Enmity Bowl.

Already upset at Redskins officials for the perceived raid of their roster, the Jets don't figure to extend an olive branch on April 3 when, ESPN.com has learned, a arbitrator will hear arguments in the case involving Chad Morton.

The restricted free agent earlier this month signed a five-year, $7.945 million offer sheet with the Redskins. The final two years of the deal were voidable, meaning they would be expunged if Morton reached certain predetermined performance benchmarks.

But the Jets, who retained the right to match any offer sheet to Morton by making him a qualifying offer last month, appealed to the NFL Management Council, essentially the league's labor arm, contesting the voidable years. The Management Council subsequently ruled that the voidable years did not represent a "principal term" of the offer and did not have to be matched.

When the Jets opted to match the offer, they did so without matching on the voidable years. Not surprisingly, Morton and agent Leigh Steinberg filed a grievance through the NFL Players Association, declaring the Jets had not fully matched the offer and suggesting that the player be permitted to move to the Redskins.

Even though the two franchises are essentially spectators in the dispute between the player and the Management Council -- albeit, each with a vested interest in the outcome of the arbitration -- the incident almost certainly will increase the level of bile between the teams.

"We want to make sure that, if the NFLPA prevails in the arbitration, that the Jets don't get a second chance to match (the offer sheet)," said Norm Chirite, the Redskins' general counsel, on Thursday evening. "We don't feel they deserve a second bite of the apple."

Since the Redskins technically do not have a role in the hearing, NFLPA general counsel Richard Berthelsen will represent Morton, and it is unknown at this point who will argue the Management Council's case. But, clearly, the Redskins and Steinberg feel the voidable years were a significant part of the offer sheet and that the Jets should have been forced to also match that component of the deal. Just as clearly, Washington would still love to land Morton, one of the game's most explosive kickoff returners.

A source close to Morton said the voidable years stipulation was a "hotly contested" part of the negotiations with the Redskins. Basically, if Morton had reached the prescribed performance levels, the five-year contract would have become just a three-year deal. Such a scenario would have increased Morton's cap number in the third year, the 2005 season.

"Our take is that the voidable years were a critical part of the discussions with Chad Morton and his representatives," Chirite said. "Those voidables were, indeed, a principle term. Obviously, we are not a party to (arbitration) case, but the Redskins certainly are interested in its outcome."

Washington on Wednesday acquired prized wide receiver Laveranues Coles, a restricted free agent, from the Jets when New York opted not to match the seven-year, $35 million offer sheet he signed with the Redskins last week.

The Redskins also signed a pair of Jets unrestricted free agents, guard Randy Thomas and kicker John Hall, earlier this month.
