Thinking about it, we have the luxury to either trade an all time CB or a pro bowl CB
Whether we decide to trade Revis or not, the whole speculation shows us how we will have a great trading chip in the offseason. Without Revis our secondary was decent last year and Cro had a career year. I would argue though that we still had to compensate for the loss of Revis by putting more people into coverage which hurt our run defense (we stunk in that regard). Plus Revis is a big presence in the locker room no matter if people believe it or not. His aura alone gives that defense a lot and numerous times players have commented on how much he helped them with their game and how to prepare (Cro, Wilson).
Cromartie could easily get us a first round pick in return or a strong player at a position of greater need. Teams these days are more than desperate for cornerback help and some teams have tremendous problems in that regard (Detroit, Washington, Giants just to name a few). He earns a lot for a second cornerback and I think he would be the guy I would trade.
Anyways, no matter what the intentions of the Jets are, with the best and one of the top ten CBs in the game plus some pretty good depth behind them (Wilson, Berry, Trufant, Lankster) we have the big luxury to really see what is out there and what we can get for one of our guys. That could lead to a great deal in the summer which could be the base for a true rebound offseason.
