I could see us playing a variety of different sets, depending on what the personnel could do:
1. Base 3-4 with Seymour-Wilfork-Warren starting, and Green-Brace-Wright (and LeKevin Smith) as backups.
2. "Big" 4-3 with Seymour-Wilfork-Brace-Warren. Very hard to run against. Sort of like the Baltimore 2000 defense with Sam Adams and Tony Siragusa.
3. "Pass rushing" 4-3 with Seymour and Warren inside and some speed ends outside (Crable, Thomas, or Jason Taylor if we get him).
4. Hybrid 4-3 with one of Seymour/Warren and one of Wilfork/Brace inside, with one big 3-4 DE and one speed rusher outside.
5. 3-4 variant with one of Wilfork or Brace moved outside to DE, and the other DE freed up to be more of a pass rusher.
I think that BB could do a lot throwing a variety of looks from the DL. And that's not even counting what he does with the LB and secondary schemes.
I think that with LeKevin Smith performing well last year and the addition of Brace, that Jarvis Green is definitely potential trade material. I'd love Green + 2 2nds for Suggs, but it's not going to happen. Karlos Dansby might be another option there, and he could play both inside and out. We could have Dansby and Thomas at OLB with Guyton and Mayo inside, and then move one of Dansby/Thomas in to SILB and have Crable/Redd/Woods outside. Lot of flexibility there. With all of Arizona's well documented contract headaches, perhaps they would be more inclined to listen to offers than Baltimore would, even though they are reportedly working on signing Dansby to a long term deal.
