In looking at the Bills roster, it seems they have more depth on the Defense Line to go with a 4:3 over 3:4. With Wannstedt as Defensive Coordinator, he has had more of his past experience running a 4:3. And with some mock drafts having the Bills taking Quinton Coples out of UNC, our defense for next year does show promise if they do draft a pass-rusher. With Kyle Williams returning and Dareus, those two could hopefully help us stop the run.
DT - Darues, Kyle Williams Backups - Torrell Troup, Kellen Heard
LB - Merriman, Sheppard, Barnett Backups - Torbor, Moats, Andra Davis
CB - Florence, McKelvin, McGee, Corner
S - Byrd, Wilson, Scott, Searcy
** I could also see the Defense panning out if they stick with 3:4 and draft OLB Courtney Upshaw, but don't believe there is as much depth for linebacker position.
