‘Essentially on a one-year pact to stay on his best behavior and follow team protocol, the Bills can walk away from Williams if he doesn’t hold up that end of the bargain or if he fails to make the type of impact they believe he can. The role for Williams still must be defined, but on paper he figures to come in on three wdie receiver sets as one of the outside players, allowing either Sammy Watkins or Robert Woods to be able to play the slot. If he can provide a red zone presence it will go miles for EJ Manuel’s progress. But since his role will likely be limited to that barring an injury, he falls a bit shorter than others on the list despite his raw skills and prior success.’
