The Buffalo Bills had one of the worst defenses in the NFL in 2010, giving up 361.6 yards per game while fielding the league's worst run defense. Most of those issues were chalked up to a defensive unit that underwent alignment and personnel tweaking for much of the season.
Heading into 2011, the Bills had upgraded their personnel in key areas and had a much better idea of what they wanted to do systematically. Yet through four games, the Bills have the NFL's No. 27-ranked defense, and they're surrendering a whopping 405 yards per game. The run defense is still struggling, and the team ranks dead last in the league in sacks.
The man behind the defense is coordinator George Edwards. As soon as the Bills hired former Chicago and Miami head coach Dave Wannstedt to be the team's Assistant Head Coach and to coach the inside linebackers, Edwards' proverbial seat heated up. Edwards is in his third season as a defensive coordinator at any level, while Wannstedt has eight, plus a further 17 years as a head coach.
Our question to you, readers: how much longer should Edwards get before Chan Gailey begins considering a promotion (of sorts) for Wannstedt?
