NFL labor talks broke off Tuesday three days before the start of free agency, leaving teams and players in a quandary about negotiating new contracts. Gene Upshaw, executive director of the NFL Players Association, spent the last three days meeting in New York and Washington with commissioner Paul Tagliabue. "We're deadlocked. There's nowhere to go," Upshaw said. "There's no reason to continue meeting." Although the contract does not expire until after the 2007 season, this is a critical period in the negotiations to extend the 12-year-old contract. Talks have been going on for more than a year. Free agency is scheduled to start Friday. If the deal is not extended, this would be the last year with a salary cap, so agents and team officials want to know how to structure contracts. For example, if there is no extension, the salary cap is expected to be about $95 million this season and annual raises after 2006 in a long-term deal would be limited to 30 percent. If the deal is extended the cap could be $10 million or more higher. The sides have agreed on a number of issues. The biggest one is changing the formula for the amount of money to go to the players from "designated gross revenues" -- primarily television and ticket sales -- to "total gross revenues," which include almost every bit a money a a team generates. However, they differ on the percentage of revenues to be allocated to the players -- the union is asking for 60 percent and the league's current offer is 56.2 percent.
