This comes up every year, so let's just get it over with. Grays defense was less than impressive (it was actually less than bad) in 2012. At the same time I read it was the first time Titans had 2 LBs with over 5 sacks a piece. So... Our defensive line isn't impressive. We have ok pass-rushing DEs (one could grow in to a star), but one is undersized and a liability against the run. We have a bunch of young DT, a mix of stuffers and rushers. Plug in a big NT and rotate Morgan, Martin, Klug, Casey and perhaps Marks and Clayton in a 3 man front, I don't think that so bad. On LB we have Ayers and Wembley on the outside and Brown and McCarthy on the inside. (Or Ayers and Brown could switch). Add a couple of players to the mix (McCarthys durability) from FA or draft and it ain't looking bad. We still need a couple of pieces, but I think it could utilize the strength or our current "front 7" better. The backfield needs improvement no matter what, 1 or 2 safeties that can cover, hit and tackle. Perhaps add an outside corner to the competition, but they seem high om Campbell. If only he can limit his stupid penalties. Verner, Sensabaugh, Mouton completes the depth chart. But after all, it's a matter of.... schema. And we need a new one. And a few players. And it's more or less the same kind of players we lack, whether it's 4-3 or 3-4. We still need a big run stuffer, we still need better and consistent pass rush from the outside. The depth just isn't there right now.
