All the talk about the secondary the last few days, but I think the way to stop Roethlisberger comes in the front seven. It is no secret that Roethlisberger loves to roll out to his right. It is also no secret that if you keep him in the pocket, he becomes a far less effective as a QB. I remember in 2007, Belichick gave Vrabel one assignment - cut off the lane for Roethlisberger to scramble right. Belichick didn't care if Vrabel hit him as long as he kept him in the pocket. It made Roethlisberger ineffective. I know they usually line up Carter on the other side, but they might swap him since he is the best outside rusher. He would probably be the best one to do this assignment (Anderson might be another possibility). Whoever has that assignment will be the key to the game on defense. I would assume Carter will get that duty.
