George Edwards, a 12-year NFL coaching veteran, was named Bills defensive coordinator Thursday. Edwards has been a defensive coordinator (2003) and assistant defensive coordinator (2002) in his time in the league. ?We are very excited that George Edwards has joined our staff as defensive coordinator,? said head coach Chan Gailey. ?He brings a wealth of experience, not only as a motivator and communicator, but he has been involved with some great schemes and we are excited about him being the head of our defense.? Buffalo?s new defensive boss will be making changes to the Bills defensive scheme, which has exclusively employed a 4-3 front the past nine seasons. ?Defensively, we will start from a 3-4 alignment,? said Edwards. ?But we will do what we feel is best for our players. We are not going to give anything away about exactly what we will do, but personnel will dictate what you can and what you can?t do. As far as the initial alignment, the 3-4 is what we will start off with and we will adjust from there.?
