Since the question has been raise about the possibility of return of Revis, I'd be all for it IF Butler is moved.
Clearly he wasn't in shape last season and clearly his skill have diminished.....some what. That being said it's not like we'd be expecting him to shut down one side of the field. We'd be expecting him to be as good or better than Logan Ryan. THAT I think he could be.
He knows the system, he knows the coaching staff. He was a good teammate when he was here and his experience could add to the development of Jones, Jones, AND Gilmore. He also is a very prideful man. I think he wouldn't want his legacy to be the player he was last season. I suspect he'd redicate himelf this off season to coming back in the best shape he can be, and have a great year on whatever team he plays for. We will have the cap room. Plus the fact that the Jets would likely pay most of his salary would be icing on the cake.
IF and only if Butler goes, I think the next best replacement would be Revis. BTW- a good contract would be to guarantee the $6MM of the Jets money, then give him another $3 in incentives, like games played, snaps, etc.
