Earlier this week, the Buffalo Bills made some waves when head coach Chan Gailey revealed that rookie inside linebacker Kelvin Sheppard is ready to assume a more prominent role in the defense - even if he stopped short of naming him a starter outright.

The move makes sense on several levels. First, aside from Nick Barnett, Sheppard is by far the team's most athletic non-pass rushing linebacker - and as the Bills don't have an overtly athletic back seven, it makes sense to get him onto the field. As smart as Andra Davis is, he's lost a step, so this move will help the Bills in the long run as well as, hopefully, right away.

Our question for you, Bills fans, is this: what's the next significant personnel change that should happen for the Bills and their No. 31-ranked defense? (Note that the term "personnel" refers to players only; let's keep George Edwards out of this conversation. He's not going anywhere.)

Some example ideas to get the discussion rolling include, but are not limited to, the following: giving Arthur Moats a more prominent role as a pass rusher; finding more playing time for other young players, such as rookies Da'Norris Searcy or Justin Rogers; or is it just a matter of getting healthy?
