C.J. Spiller, RB, Buffalo Bills: Spiller was expected to add a dynamic presence to the Buffalo offense last season, but it never happened. He was slowed by injuries and had only one start. He played in 14 games, rushing for 283 yards on 74 carries. That 3.8 per-rush average isn't too impressive for a player with his speed. With a year under his belt, I think that speed shows up a lot more this season. Look for a 1,000-yard season from Spiller with a lot of big plays
