Nick Barnett

The Buffalo Bills have begun reshaping their defense under new coach Doug Marrone by releasing two veterans: linebacker Nick Barnett and safety George Wilson. The shake-up takes place a little over a month since Marrone took over after Chan Gailey was fired following three losing seasons.

General manager Buddy Nix said the cuts were made Monday with the intention of moving the team forward and freeing up spots to allow Buffalo's younger players to step into those roles. Barnett is a 10-year NFL veteran, who never missed a start in his two seasons in Buffalo after signing with the team in free agency.
