We've haven't seen Shawne Merriman operate at full throttle in years, but the Bills defensive end says he's ready to make a difference. "One hundred percent," Merriman told The Buffalo News. "I feel very comfortable right now." On the rebound from shoulder and Achilles surgeries, Merriman can't be relied on for consistent production. Merriman has played in just 23 games and logged just five sacks since 2008.
