Personnel: The Bills have some building blocks on offense, such as Manuel, wide receivers Steve Johnson and T.J. Graham, and left tackle Cordy Glenn, but their most dynamic playmaker is C.J. Spiller, who is a threat to score on every play, whether he is a runner or a receiver. He left the game in the third quarter with a knee injury, but before then the Bills used both Spiller and fellow back Fred Jackson on the field at the same time. On defense, their best player is pass rusher Mario Williams, though he had a quiet afternoon against the Jets. The Bills were missing three key contributors in their secondary — starting safety Jairus Byrd, starting cornerback Stephon Gilmore and backup Ron Brooks — and it showed.
