When he was with the Pats a couple of years ago, he was not very good. He started before Belicheck purged the Pete Carroll trash and this guy was part of it. He lacks aggressiveness and has poor feet.
He started on a Super Bowl team and then got beat out the following TC. What does that tell you? I guess if you are desparate for depth, maybe he's worth a look. But you better hope he doesn't have to play.
