We are far from settled at CB. McGee is old and often injured, as reflected by his contract restructuring. McKelvin is in a contract year and who knows what is going to happen with him and how he will perform. Florence is a good asset for the team to have as a nickel/dime CB (same situation as McGee). Williams is the only CB that looks sure to be a starter on opening day. Rogers is a coin flip, but I do love how he performed while returning kicks late in the year. You can never have enough good CB's in this league and I can guarantee you that Buddy Nix does not think that we are settled at CB.
Have you forgotten about Mario Williams, Kyle Williams, Marcel Dareus, and Mark Anderson?
