NFL player leadership is still divided over the thought of a 17-game season.

Player reps fell into three categories when discussing the proposed new Collective Bargaining Agreement, sources told ESPN -- those who never want 17 games, those who will accept it with tweaks to the deal, and those who accept it as is.

Those reps held a conference call Friday and were set to vote on the deal, but getting the two-thirds majority was far from a slam dunk, a source said. The players union decided to postpone voting, giving all parties involved a few days to sleep on the proposal and meet at the NFL combine in Indianapolis.

"Anything is possible at this point," said a source involved.

The players are set to meet with NFL officials on Tuesday and could vote as early as Wednesday but hope to go back to owners and continue negotiations, according to ESPN's Dan Graziano.

But the owners have no intentions to renegotiate the offer, according to ESPN NFL Insider Adam Schefter, who also reports the NFLPA and NFL Management Council have pushed back the start of the franchise tag designation period from Tuesday, Feb. 25 to Thursday, Feb. 27. Teams will now have until March 12 to decide whether to tag a player. NFL teams currently have the option to tag two players (using either the franchise or transition tag), but a new CBA would limit to one tag per team.

Among the tweaks players from that middle category would like to see, according to sources: An increased revenue share, improved pension and more improvements to working conditions. The NFLPA executive committee voted 6-5 against recommending the proposal, which offers a guaranteed revenue share of 48 percent in 2021, with the chance to increase to 48.5 percent upon the enactment of a 17-game season, the start of which is yet to be determined. The current CBA expires March 2021.
