---One of the Bills biggest offseason questions has been answered: The defense is moving back to a 4-3.
In announcing new additions to the coaching staff, Bills coach Chan Gailey also said the defense is moving to a four man front in 2012 which isn’t a huge surprise.
Because of injuries and personnel, the Bills have been playing with a four-man front since the Week 8 victory over the Washington Redskins. The Bills fired defensive coordinator George Edwards and replaced him with Dave Wannstedt, who has employed the 4-3 scheme since his days as a DC under Jimmy Johnson at Miami (Fla.).
"We're going to start in a four-man front,'' Gailey said. "When we hand you a lineup card it's going to have two defensive tackles, two defensive ends and three linebackers."
