I honestly think the Seahawks should be contenders for best secondary ( yes I am a huge homer on this subject.)
Browner Pro bowl corner, not amazing top end speed but almost elite change of direction for someone his size, elite against the run, elite playmaking skills, elite press coverage, good man to man skills, great zone coverage. He also did this
Richard Sherman, another big physical corner, elite man coverage, good zone, great against the run, and a sure tackler.
Kam Chancellor Elite hitter, elite against the run, and proved himself as solid in coverage.
E.T Elite FS, IMO the best free safety in the league. Even when he isn't making plays he is allowing other to make plays because of his range they CAN play a single high safety. Best range of any FS in the league, awesome against the run and a sure tackler.
If William Gay hadn't run off to Arizona I'd say something about the Steelers secondary based off the entire 2011, despite what people living in the past and/or overreacting to the most recent single game believe.
I'm a homer but I wouldn't trade the chiefs WR corp and secondary for anyone in the league.
Bowe/Breaston/Baldwin, who had a slow start but showed plenty of promise and then Moeaki who had a very nice rookie season. and Boss should be a solid #2 tight end.
Not much needs to be said about our secondary.. top 3 duo in Flowers/Routt. Arenas is one of the better nickel corners in the league. Kendrick Lewis has showed promise but still needs to get better. And Eric Berry just needs to stay healthy
