Hall of famer has nothing to do with it. He's going to be 30, he has to put up Philly type numbers this year to prove he still can. 300+ carries, a lot of catches out of the backfield, 1500+ yards rushing. Feature back by every definition.
So you think the Bills are going to carry a 30 yr old who is the highest paid RB in the league on their roster next year in the middle of a rebuild? You are dreaming. They are dumping the high contracts and high contracts for RB's are unnecessary. If they can get an asset for him so that they can rebuild they will. This is a team being built for 2-3 yrs from now
