If he's counting on a diminished Bills' defense, he's in for a rude awakening. Daquon is back, Douglas has replaced White and Bernard and Dodson have been playing very well. He should be more worried about how his offense is diminished with the loss of Waddle, Mostert and their starting center, and with Hill limited.
As for the Bills on offense, Josh always comes to play against Miami. He averages 3.25 TDs and 0.92 turnovers against them.
