Todd Graham's Arizona State Sun Devils sit all alone atop the Pac-12 South standings, but in all the positives so far this year, the recent lack of a run game might be cause for concern, writes Brad Denny at House of Sparky.
The Sun Devils have averaged 2.9 rush yards per attempt in their last three games against the Missouri Tigers, Utah Utes and California Golden Bears, and they've only put up 123 yards per game on the ground.
A potential spark that ASU is lacking could very well be senior captain Cameron Marshall, who only has 164 rushing yards on the year. His 49 attempts are more than any other back, but junior Marion Grice and freshman D.J. Foster each sit just over the 200-yard rushing total.
Last year, Marshall was a 1,050-yard rusher and tied the school record with 18 touchdowns in a single season. He struggled with a hamstring injury during training camp, stalling his development in the new offense.
