The Bills have made another transaction on Tuesday. After signing LB Andra Davis, the Bills have agreed to terms with free agent DE Dwan Edwards, according to ESPN's Adam Schefter.
SB Nation's Bills blog, Buffalo Rumblings, has the rundown on Edwards.
Edwards, 29, has spent the entirety of his six-year career with the Baltimore Ravens. An excellent run defender, the 6'3", 315-pound Edwards has played defensive end in Baltimore's 3-4 system, contributing 47 tackles, a sack and a defensive touchdown to the league's third-best defense in 2009.
The Bills of course are switching to a 3-4 defense in the upcoming season so any advantage there should be a help.
