The Bills made a big splash with the offseason acquisition of DT Marcus Stroud, whose physical presence will improve a run defense that ranked 25th in the league in allowing 124.6 ypg) last season. Stroud not only can defeat the double-team, he also should provide an upfield push that should throw off the timing of the ground game. He will take a lot of pressure off DT Kyle Williams, who is a short, powerful player who shows intensity and solid technique.
