Personally me thinks DeW trade value is almost zero. Maybe he thinks he is going to be cut or it is normal to remove your name plate from your locker at the end of the season as next season you may be assigned another one
DRob has been a dissapointment - I'd try to get rid of him if they can. I like Pouha and Mosely but would love a veteran NT.
I have been in favor of trading him instead of Vilma. I think Vilma would be fine with a 335lber in front of him. D-Rob has trade value for 3-4 teams where he's a very good DT. Trade Pennington, D-Rob and Justin Miller for picks. I would imagine Miller still has good value with his KR ability (a big thing right now in the NFL with people like Hester) and he has little value with us because of Washington.
This guy could have been a dominating tackle in a 4-3 but the last few years of his career have been wasted, and now he is not worth anything because everyone thinks he is a flop. The Jets are going to be one different team next year...
I wouldn't read into that, also they will probably just rework his contract, he is too valuable to this defense and it will be hard to get equal value in return.
