As someone else said a few minutes ago, the offense worked on otherworldly play from Josh, the O Line and Cook having a career year. They also managed to reduce turnovers to an amazing minimum. That is likely to regeress at least slightly to the mean next year. That means more players need to come to the party. Outside of Shakir, and even he had a slight decline at the tail end of the season, I have little faith in the WR room as it stands. The Bills need something different in there.
