The Steelers started to really assert themselves on the ground in the second quarter after a comparatively sluggish opening quarter, and they extended their lead on St. Louis to 10 on a 10-yard run by John Clay, which can be seen below.
Clay runs right and has a pretty clear path to the end zone; a Rams defensive back appears to whiff on a potential touchdown-saving tackle. It was Clay's first carry of the 2011 season.
But Rashard Mendenhall did the bulk of the work on the ground for the Steelers; he has 97 yards on 10 carries, including a 52-yard scamper.
Steven Jackson had a solid half for St. Louis and finished with 57 yards on 13 carries and surpassed 1,000 yards rushing for the seventh consecutive season. Kellen Clemens struggled to get the passing game going and is just 6-17.
