GRAPEVINE, Texas -- The NFL was still without labor peace after team owners met for most of Tuesday without reaching any agreements.

Yet another deadline looms Wednesday, with owners trying to decide whether to accept the union's latest proposal.

A decision on whether to extend the collective bargaining agreement was unlikely to come down until close to the latest deadline of 8 p.m. EST on Wednesday. Before making a deal with the union, the owners must resolve their own differences over expanded internal revenue sharing. If they don't get that straight, a CBA deal is unlikely.

The Tuesday meeting ended at 10:15 p.m. ET, completing more than eight hours of talks, ESPN.com's John Clayton reported. No vote was taken, and most of the evening was spent discussing at least three different revenue sharing plans, plans that have been discussed for years.

Raiders owner Al Davis joked that a lot of people were in the room "giving money away." While the discussion was good, no revenue sharing deal was close to settled. "Whenever you discuss revenue sharing, it's like Groundhog Day," Colts owner Jim Irsay said.

Steelers owner Dan Rooney was asked if there was any progress as the meeting ended. "Nothing worth talking about," he said.

Talks were to resume at 9 a.m. ET Wednesday, giving the owners 11 hours to get word back to the NFLPA about whether they accept the proposal or not.

"It's going to be a while. Quite a while," said Buffalo's Ralph Wilson, one of leading proponents of revenue sharing.

Much of the early hours of Tuesday's meeting was spent simply listening to commissioner Paul Tagliabue go through details of the union's proposal. Then Tagliabue outlined revenue sharing, but there was no discussion before the owners broke for dinner.

"We haven't punched anybody yet," said Rooney, who described Tagliabue's remarks as "Excellent. Super."

"He described how the owners and players should be in this together for the good of the league," added Rooney, who has helped to solve past labor disputes.

League spokesman Joe Browne said Tagliabue had agreed with Gene Upshaw, the executive director of the NFL Players Association, that the owners would have a decision no later than 8 p.m. ET Wednesday. That would come as the union, which is meeting in Hawaii, holds its executive board session.

"It was a good day," Browne said after the meeting broke up for good Tuesday night.

One of those who supported Tagliabue was Oakland's Al Davis, for decades the NFL's most consistent maverick, who noted that the league had had enough of labor disputes.

"I love my country and I love my league," Davis said as the meeting broke up for the day. "People who have been through this in the past want something good to come of it. What's good is another question."

There seemed to be some hope they would reach an agreement that would extend the contract that runs out after the 2007 season. It came from Dallas owner Jerry Jones, who is 180 degrees away from Wilson on sharing, but suggested for the first time that he might have to give in a bit to let the owners solve their dispute.

"We want to play football," Jones said as he entered the meeting. "We have an obligation to everyone, particularly our fans.

"My gut is we're going to come up with something, but it's still up in the air. It's going to be long and drawn out and tough."

Finding a solution now is critical because free agency, pushed back twice, is scheduled to start Thursday with a $94.5 million salary cap that could go as much as $10 million higher if there is an extension. And although both sides have agreed there will be no more extensions there would be one more if there is an agreement -- until 12:01 a.m. Friday to give teams time to get everything in order.

If there is no settlement, then 2007 would have no salary cap and create the kind of uncertainty that neither side really wants.

Revenue sharing hasn't been dealt with during the negotiations, even though Upshaw has contended all along that no agreement can be reached without it.

If nothing else, the tone of the owners was far different at this meeting than in New York last Thursday, when they took just 57 minutes to reject the union proposal. Later that day, they extended the deadline for free agency for three days and again extended Sunday night just as it seemed talks had broken off.

That led to this meeting and the discussion over revenue sharing, which will be necessary to meet the union's proposal for just under 60 percent of the league's total revenues.

Low-revenue teams such as Buffalo, Cincinnati and Indianapolis say high-revenue teams -- Dallas, Washington and Philadelphia, for instance -- should contribute proportionately to the player pool because they can earn far more in non-football income such as advertising and local radio rights. Those high-revenue teams might contribute only 10 percent of their outside money compared with 50 percent or more for low-revenue teams.

If there is no agreement, it would leave a number of free agents commanding far less than they thought they could get and a glutted market filled with veterans who could be cut to provide cap room.
