I'll let you know when I see the contract.
His hit for this season, as you've got posted, is under $3 million. Unless the Patriots are going to let Wilfork hit the market, he's going to get some new money this year and the cap will need to cover it. And Wilfork's not the only player who's contract 'needs' addressing. Between the RFAs and the UFAs, the Patriots are either going to need to be active with contracts this season, or they're going to be bidding on the open market just to keep their own players next season.
Gostkowski
Faulk
Seymour
Wilfork
Green
Neal
Kazcur
Mankins
Are just some of the players who'll be free agents after this year. I don't expect that the team will want them all to return, but there's going to be some that will need good money if they're to be convinced to stick around. One could, of course, apply the word 'need' in such a way as to ignore all of this, but that would be a mighty tight reading of it, especially given that Wilfork's talked about his extension.
Jarvis Green would net $2 million in cap space if the team cut him. I certainly don't consider that an impossibility.
