Well this may not be true, The Bills are loaded with Ohio State players and he loves these kids, it looks like he's adapting to Fewell's (and Jauron's) defense nicely as well and he's the perfect corner for the system he has right now.
Plus with the team starting to win games now and all the positive upside this team appears to have, as long as we offer him the money he's looking for (which is overpriced but we do have the cap space and it's well worth overpaying a player of his caliber), as long as the money's there, I don't see why he wouldn't re-sign.
I doubt he'll be too excited to suddenly have to jump into a new system which he has to learn. It's a lot more promising this offseason getting a deal done than it was last season, that's for sure.
