Mario Williams has ''Super'' expectations for the Buffalo Bills this season.
The defensive end arrived at training camp Friday wearing a cap with the Superman ''S'' stitched on its front. It's something that provides him motivation.
Williams and the Bills then have much to prove if they intend to start resembling men of steel in preparing to open camp Sunday.
Williams is coming off an inconsistent first season in Buffalo, during which he failed to play to the six-year, $100 million contract he signed in free agency.
The Bills are coming off an offseason overhaul. They brought in a new coach (Doug Marrone) and general manager (Doug Whaley), purged numerous veterans, and drafted quarterback EJ Manuel in the first round.
Williams remains confident the Bills can be competitors this season.
