Which player do they need to re-sign?

Khaled: It’s a bit of a no brainer. Paul Poszlusny is the only guy on their list they should really be looking at keeping. He struggled as the Bills switched defensive schemes, but he’s a talented player and if they can settle on something, he’ll thrive. Best fit in a 4-3, so what kind of balance their hybrid has will be something to watch.

Sam: Pos is the only Bills player they should be concerned with locking up. His performance in the 4-3, along with Kyle Williams, should really lead the Bills to settle on that defensive front, rather than persisting with 3-4 looks.

What area is the team’s biggest need to upgrade?

Khaled: They need to be less reliant on Williams for their pass rush. Chris Kelsay struggled rushing from two or three point stances, and it’s asking a lot of Arthur Moats to build upon an encouraging but hardly amazing rookie year. They need some proven pass rush whatever front they end up in.

Sam: As much as they need pass rush, they can survive there. No, what they really need is some better blocking. Fred Jackson is very solid and their offense has some other legitimate skill players. That will all go to waste unless they improve their blocking and protection.

How do they upgrade that area?

Khaled: Simple. They go out and make Matt Roth a highly paid man. He’s an extremely talented and complete outside linebacker. They’ll need to manage his snaps, but he’s better than anything they have on the roster (especially since it looks like they’re going to persist with plenty of 3-4 looks).
