Last season, the Bills had the league's worst run defense. The thought of the Bills defense facing Jamaal Charles would make Bills fans puke.
But this year is different.
The Bills made huge upgrades on defense to help stop the run. They drafted big run stuffer Marcell Dareus third overall in the draft, and he will be a big part of the defense this season. The Bills also drafted defensive players with their second and third picks in the draft in cornerback Aaron Williams and linebacker Kelvin Sheppard.
Buffalo also gets Shawne Merriman on the field for the first time in a Bills uniform. With Merrriman healthy, teams should be scared.
The Bills also signed linebackers Nick Barnett and Kirk Morrison. Nick Barnett was a massive upgrade and Kirk Morrison was a nice signing because he adds starting experience and depth.
Jamaal Charles is a beast, but he will not have an easy time on Buffalo's improved front seven which includes Dwan Edwards, Kyle Williams, Marcell Dareus, Chris Kelsay, Andra Davis, Kirk Morrison, Nick Barnett and Shawne Merriman.
Watch out for Buffalo's defense this season.
