Wilkerson has been great this season. It's hard to really tell when he is literally surrounded by trash in the front 7. Coples/Wilkerson are really the only reason to follow the team at this point.
Hopefully a fresh set of faces on offense will make that side fun to watch next season. I swear if Rex is not on board with finding a replacement for Sanchez THIS year in the draft he needs to be fired on the spot. Bring in a new GM and let him have a meeting with Rex. It should be his call.
