Charles Woodson (reportedly) advocated the signing of Nnamdi before he was franchised. I don't know how hard or whatever he pushed, but with the Raiders being so bad for so long, I could see Charles talking Nnamdi into coming here for a lower price for a 2 year contract to get a ring and then Nnamdi cashing in on Free Agency in '13.
I won't get my hopes up, but it certainly can't be dismissed either.
The emergence of Sam Shields I feel make this less likely in my opinion. We have two young promising guys in our secondary.
Also, the CBA plays a huge factor in this.
