I don't think he's as bad as he has looked the last few weeks. He's usually not in bad position, he's just not making plays on the ball. The injuries to Hyde, Edmunds and Poyer haven't done him any favors, and it certainly doesn't help, either, that he has faced two of the best WRs in the NFC in the last three weeks. I still think he can be a solid 2nd or 3rd CB, but he's still a young CB and they're asking a lot of him right now. I'm not surprised he's struggling, but I also wouldn't give up on him.
