They aren't gonna cut McCoy though they do have a log jam at the position. I suspect they will cut T.J. Yeldon and that would be a big name to cut loose. McCoy is not the McCoy of old. He is not elusive anymore and will see less carries than he has in year's past as Buffalo will give the ball more to Devin Singletary, a mid round draft pick they like.
Talking trade, not a cut and sign. But hes not playing for free. Best is you have him cut, have the Pats signing him, when they have Sony Michel at RB and that this is a move to get them to the SB. Typical, every player cut or traded on the downside of their careers will go to the Pats and be a major reason why theyll win the SB. Other than it rarely if ever has been true, why not.
