I've been reading a lot about the secondary through multiple threads, and I wanted to share some thoughts.
Thi unit was a mess from Day 1. McCourty was not great at CB, good and ok at S. Gregory was playing ok, hurt, playing bad...T Wilson was a rookie who looked lost at times. Arrington was decent in the slot. Talib was good when he got here, but dealt with nagging injuries, and missed most of the playoff loss. Just a total mess. To top it all off, they had 0 veteran leadership. Who was it? McCourty? Arrington? Nobody. BUT, I still think some of the pieces were there. For a short, 3-4 game stretch, we saw the D with Talib at CB, and McCourty at Safety, and Dennard playing...and it looked pretty good.
Now to 2013:
Day 1: McCourty will be at FS. Talib will be at CB, Dennard will be at CB. A Wilson is likely going to be on the field at SS to provide the Veteran leadership they were so severely lacking.
T Wilson and Gregory will have had a whole offseason to prepare, and should either look better, which would be nothing but good for the team...or will probably be gone. One or both.
Arrington should be fine in his slot, as long as he isn't one of these guys that gets a little money and tanks.
Add in a pair of Rutgers, who at least know each other well and have some familiarity with McCourty...
Suddenly you (seemingly) have a much more cohesive unit that showed, during their brief time together, that they CAN play well.
There was a decent foundation to build on, and it looks like they added a little structure on top of it.
