When the Pittsburgh Steelers play the Cincinnati Bengals, they know that they always have to watch out for something different during the course of the game, whether it is an unconventional alignment for the offensive line, or the occasional Wildcat that they like to run with Mohamed Sanu, who excelled in that role during his college career.
In general, the Steelers have been prepared for it when they have played the Bengals. Sanu has three carries in his games against the Steelers over the course of his career, gaining a total of 11 yards.
