Which Raven will be the biggest concern for the Steelers' offense?

John Clayton: This may sound surprising, but I think Ed Reed is more of a worry than Ray Lewis. Lewis is a leader and he's playing so well behind Haloti Ngata, but Reed is the player on the Ravens' defense who could frustrate the Steelers' offense with an interception or two. Roethlisberger has to be wary of turnovers. Scoring will be tough, so he can't give the Ravens the chance for easy scores. Reed might be able to confuse him with some coverages and steal an interception or two. Lewis no doubt will be the main guy in trying to stop the Steelers' running game. But turnovers could determine this game, and Reed has been a turnover machine in the past eight weeks. Roethlisberger has to keep the ball away from Reed.

James Walker: You never cease to amaze me, John, because I was thinking the same thing. Reed's private nature doesn't get him the superstar treatment and the media attention that he deserves. But opponents know he's the first player they must be aware of. Here is a stat to support that argument: Baltimore is 4-0 this year when Reed scores a defensive touchdown. He is the biggest defensive game-changer in the NFL. Lewis and the front seven are going to be tough to run on. So at some point, Roethlisberger will have to test Reed's prowess through the air.
