After just one season together, Arizona State head coach Todd Graham will have to fill a spot on his coaching staff as running back coach Larry Porter left the Sun Devils to join the Texas Longhorns.

Porter joined Graham last season after spending two seasons as the head coach at Memphis. His work with the running backs and Graham's offense helped Arizona State improve its rushing attack by nearly 70 yards per game. In 2012, the Sun Devils ranked 25th in the country in rushing yards per game, averaging 205.3 yards per game. Arizona State was 85th in the country in 2011 with a per game average of 129.1 yards.

The Sun Devils didn't have a running back top 1,000 yards under Porter, but they did have three with at least 493 yards. D.J. Foster rushed for 493 yards, Cameron Marshall finished with 582 yards and Marion Grice led Arizona State with 679 rushing yards. The Sun Devils had possibly their best game on the ground in Porter's final game with the team. ASU ran for 380 yards in its bowl victory against Navy.

In addition to ASU and Memphis, Porter has also coached at LSU, Oklahoma State, Arkansas State and Tennessee-Martin.
