Back in the day, the Green Bay Packers had their power sweep, which they probably ran about a dozen times a game. Everyone knew it was coming, and they basically just defied anyone to stop them. The point is, good running games behind good o-lines are hard to stop. LT, Alexander, Barber, you trying to tell me defenses don't know these guys are getting the ball? Good offenses don't care. They'll just take it to you and stuff it down your throat.
Yeah, Big Ben is no Johnny Unitas. He might not even be another Terry Bradshaw or even a Terry Hanratty. But he doesn't have to be. You may not like the Steelers' formula, but it wins ball games.
