Buffalo Bills: How does this team fit its personnel into a 3-4 defense?

It's been an offseason of change in Buffalo as the Bills desperately try to break out of an endless cycle of mediocrity. Perhaps the biggest change will come on defense, where new coordinator George Edwards will toss out the NFL's last fad scheme (Cover 2) in favor of the NFL's current fad scheme (the 3-4).

A move to the 3-4 probably favors Buffalo's younger players over its veterans, particularly at linebacker. 2009 first-round draft pick Aaron Maybin was pretty much invisible as a rookie, as he failed to record a sack. He simply doesn't have the size to take on run-blocking linemen as a 4-3 end, but he will have more freedom to make plays in the new scheme.
