On the defensive side of the ball, the Bills look stacked and vulnerable at the same time. How is that even possible? Think about it...the talent is solid, the defense shows in flashes, but yet we give up huge runs, a lot of points, and at times our coverages just STINK. So, this becomes an interesting challenge - playing GM and seeing where this unit can be improved.
I'll look at the defensive unit in groups, just because:
DL - We repeatedly hear the Bills have one of the deepest and best D-lines in the NFL, yet we get gashed repeatedly. However, I really see this unit as the solution, not the problem. Mario is the veteran stud and I imagine Kyle being the heart and soul of the DL. Dareus is the prankster. Add in the extras like Hughes, Branch, Carrington, et al and you've got a very studly unit. Can always use improvement but certainly not the worst part of the defense
LB - Kiko should continue to improve, I really like Manny Lawson on the outside and I think Hughes plays some as a linebacker (where I think he fits best). That's about all I am happy with on this unit. I think there's a lot of room for improvement and depth here.
DB - The defensive backfield is a mess. Gilmore has not progressed this year, but I'm not writing him off, much was due to injury. I think Byrd is worth keeping, I'd pay him, not piss him off more by tagging him again. My favorite player in this unit is SAFETY Aaron Williams, which appears where he was born to play. McKelvin's cover skills are hit or miss, and you need five or six DBs to play in this NFL. Speaking of depth, we've seen growth from Robey and Brooks. Leonhard is probably not back next year...
So, if I were drafting for defense (and using their 4/3 alignment):
3. LB Depth
4. DB Depth
5. BPA Defense
