I think for a 34 they have 3 Dlinemen and 2 ILBs, their main need is at both OLB spots. Need 2, maybe 3 players (Depending on your opinion of Edwards/Carrington/Troup).
I think for a 43 they have 2 Dlinemen (regardless of Kelsay's play he's getting old and will need a replacement soon) and 1 MLB (Barnett) and no OLBs. Likely need 4 players.
Therefore I think they're closer to being at least average at all 7 "front 7" spots in a 34.
I don't know what his responsibilities are, but the defense has been terrible, and he has a hand in it. I wouldn't blame them for not wanting to give him more responsilibity and wouldn't mind if he's also replaced.
