If the game plan is to go " all in" for Romos remaining years then why not. Worry about the Cap consequences after Romo and Witten Retire then rebuild. Heck Dez only has like 3-4 years left too at 27
Would trade Tyrone Crawford (prefer Maliek Collins, but Collins has little scheme fit with Jets so lacks versatility or trade value like a Sheldon Day or Jonathan Bullard plus all the big dollars are not tied up in one position, 3 tech), Ron Leary (or Terence Williams) and a future 2nd for Wilkerson.
Crawford is a great athlete and still has upside (can play inside or outside in 4-3 and has size/length to play 3-4 DE which Jets' employ) but he is more athlete than football player at this stage and more importantly has trouble staying on the field. Mo Wilkerson has already put up multiple double digit sack seasons and a pro bowl.
Wilkerson is already a gamechanger and putting him on the DL will actually improve all the players around him, especially DLaw who needs his one on one's to have maximum impact. Mo Wilkerson would essentially be the Cowboys' 2nd round pick in 2016 while Jaylon Smith would be our 2nd in 2017.
The trade is win-win. Sign Dom Easley for vet min with incentives too.
