Warner's not a mobile QB, nor can he really scramble all that well. that aggressive, blitzing, 3-4 defense of the Steelers will rip them to shreds if the Cards cant utilize the run game, from the get go. By doing this, it'll have the Steelers secondary playing up on the field, and will give the Cards' receivers' an excellent opportunity to open up the passing game. Edgerrin James, isn't at the same level he was a few years ago, and the Steelers defense against the run is solid. On the flip side, the Cards defense, i think at least, will be able to shut down the run, and pressure Big Ben a bit. The only major problem is, the Steelers have a VERY healthy run game, AND passing game. If they can utilize playaction, and keep the Cards D confused, they'll win it by 14+.
