I'm on record in predicting the Revis deal will be announced by Friday (3/6) That will drop the Revis
cap number to around $15MM for this year on a 3 year deal (That's 10MM on the new deal, plus the $5MM carry over from last season.)
That should give the Pats only around $10MM in cap relief, so perhaps they might want to do some things to be able to back load it some more without over doing it. Perhaps making it a 4-5 year contract and lowering the cap rate to 8-10MM for this year. That would allow the Pats to franchise McCourty and still get under the cap by 3/10 so they can delay decisions on Wilfolk, Mayo, and DA for another day, as well as give them until July to get McCourty's deal done.
Needing to get McCourty franchised AND be under the cap will give the Pats another reason to get Revis done. And while its just another bargaining chip for Revis, I still don't believe the mediots who are predicting a $16MM/yr deal. The top of the market has been set by younger players who are just as good at $14MM/yr. It would make no sense to pay THAT big a premium to the market for an older player with fewer physical gifts.
