Teams have learned after the playoffs two things. Know where Troy Polamalu is at all times and you can no longer just play the run against the Pittsburgh Steelers. It was obvious watching the playoffs that defensive coordinators were thoroughly confused and frustrated trying to figure out what the Steelers were going to do. The Steelers are no longer one dimensional. They don't fear Roethlisberger because of a coach everyone knows prefers the running game and a sub-par receiving core except for Hines Ward on behalf of the Steelers.
