No chance that Bennett will take a paycut when he quit on the Bears last season because of his contract.
To me this is just an one-year rental. We take his $5 million cap hit and let him walk next offseason. I'm pretty sure we still have enough cap space to extend Hightower this offseason even with the Bennett addition, unless you are suggesting that the Pats should do more in addition to Bennett then yes, we don't have enough cap space, but remember we still have Cannon and Amendola's contract that could be restructured or even dumped.
