No evidence other than a personal feeling. Maybe due to his being suspended and being in a contract year. Maybe he comes back when other backs didn’t just cover for him but excelled?

What do you mean "comes back"? He was there for mandatory mini-camp. He'll be there for training camp. He only missed "voluntary" OTA's because he was training with a route running and speed expert. Numerous veteran players train on their own during OTA's. Everything I've heard from players concerning his suspension is that he got a raw deal and they feel sorry for him and support him 100%. And players are always supportive of other players concerning contracts. Besides, there hasn't been anything negative concerning his contract anyway.
