BUFFALO BILLS (6-10)
Strengths: DL, RB, WR.
Weaknesses: QB, OL, S.
What's New: Defense switching to more conventional 4-3 scheme under Schwartz, former Lions coach who took over after Pettine left to become Browns head coach. Though Bills set franchise record with 57 sacks last season, they struggled stopping run by allowing 150-plus yards rushing seven times. Schwartz's defenses have solid track record against run, and addition of Spikes in middle should help plug holes.
Expectations: Bills hope to end NFL's longest current non-play drought of 14 seasons, but have plenty of work just to get out of AFC East cellar.
