Again, nowhere did I say he shouldn't be back and nowhere did I say we should bring in a guy and anoint him as the starter. He's not a terrible option and should remain the starter until we have a better option.
Taylor isn't the reason the Bills missed the playoffs, but he isn't going to have this magical improvement down the road.
