After all the success the Ravens had last year plugging in players, they might be thinking about getting younger and healthier personel.
The coaching staff did a great job last season developing talent and they must be confident that trend will continue.
We are heading toward another 20-25% roster turnover.
I'm not panicing because I remember 2002. Only Ray, Boulware and Cmac returned on the D and it was still good.
I still would like to keep Rolle because he provides depth, leadership and great experience. I do understand the durability and Cap concerns. It's scary to think of a weak secondary after watching one in '96, '97' and '98. The Ravens couldn't win...even with a very good offense.
But....they may be thinking 'get younger/get healthier/get more consistant performance'.
