Well, that depends.
Tennessee will and should pay Derrick Henry. He is the best RB in football currently, the best player on their team and his contract is up. They have no other choice. He is the Tennessee Titans identity.
He isn't going to hit the market, no way no how. I'm not sure why the discussion is even taking place, but if he were, it wouldn't make financial sense for a team like Buffalo to sign him to be a 1-2 punch with Singletary.
The guy Buffalo should be looking at is Jordan Howard. It's a perfect fit.
