CP just said you can't win a super bowl with meh corners.
I just wanted to point out.
1st and very early 2nd round DBs last 4 years:
2010 DBs: eric berry (s), joe haden, earl thomas (s), kareem jackson, devin mccourty (s), kyle wilson and patrick robinson.. chris cook (34th overall)
2011 DBs: patrick peterson, prince amukamara, jimmy smith, ras-i dowling (taken 33rd) and aaron williams (34th)
2012 DBs: mo claiborne, mark barron (s), stephon gilmore, dre kirkpatrick and harrison smith (s)
2013 DBs: dee milliner, dj hayden, kenny vacarro (s), eric reid (s), desmond trufant, xavier rhodes, matt elam (s), johnathen cyprien (s 33rd) and darius slay (36th)
Seahawks for example had a great secondary and a great defense 2 years before having a good pass rush.
Carolina last year had an average at best secondary, but a great defense overall because of the front 7.
Basically, if either section of your defense is truly elite, you are going to be able to make up for some of the shortcomings in the other side. I wouldn't say one is better than the other.
The one thing you have to be able to do is stop the run, or it doesn't matter if you can cover receivers or rush the QB.
See Detroit. Taking all those WRs in the first round for so long.
