The Steelers have the sixth best rushing defense in the league. The last time these two teams met, in Week 10, Cedric Benson and Bernard Scott combined for just under 100 rushing yards. That's about average for the Steelers defense. They allow an average of 96.3 rushing yards per game.
I'm not asking both Benson and Scott to each run for over 100 yards but if the two of them could combine for closer to 150 yards, it could take so much pressure off of Andy Dalton and the passing game.
The Bengals rushing offense has been underwhelming for the most part so far this season. Luckily, Dalton has been much better than most expected him to be and he and the passing offense has picked up the slack. That works against teams like Cleveland but against teams like Pittsburgh and Baltimore, the Bengals have to play a complete game and that means they need to be able to move the ball on the ground and through the air.
Even if they can't gain around 150 yards on the ground in Pittsburgh on Sunday, if they can just break off a handful of big runs here or there, it could at least keep the defense honest and open up the play action section of the playbook. A nice balance of rushing and passing plays will keep the Steelers defense on their toes and should be able to provide the offense with some extra room to work.
Benson has never had a 100-yard game against the Steelers. In fact, he's never rushed for over 80 yards against them. Can you imagine how much easier of a time the Bengals could have if Benson rushed for over 100 yards on Sunday against the Steelers? If he can do that, the Bengals chances of winning would go up tenfold.
