Senior MARCUS MASON:
Started 11 games in 2013 and was voted team captain five times. Led the team with 865 all-purpose yards. Was tops in rushing with 429 hashes and second in receptions with 52 for 390 yards. Missed most of the spring season with an ankle injury and will come into fall camp in catch-up mode.
Junior TEONDRAY CALDWELL:
Dubbed the hardest working back on the roster by assistant coach Jim Mastro. Made five starts in 2013 and collected 744 all-purpose yards: 271 on the ground, 130 via the air, and 343 on kickoff returns. Was an honorable mention All-Pac-12 selection at kick returner as a true freshman in 2012.
Senior THERON WEST:
He was a special teams mainstay in 2013, blocking two punts, but came out of seemingly nowhere to start the New Mexico Bowl and didn't disappoint, rushing and catching for a combined 67 yards and one touchdown. He carried that momentum into the spring season and figures be the No. 1 RB on the depth chart when fall camp opens.
Freshman JAMAL MORROW:
After redshirting in 2013, Morrow came into the spring season ready to stake his claim. He put together an impressive 15 practices and scrimmages, showing off speed and an ability to make hard cuts. Mike Leach said after the final scrimmage that if the season started tomorrow it would be Morrow and West getting the most reps.
Freshman GERARD WICKS:
Like Morrow, Wicks is coming off a redshirt season. At 5-11, 202 pounds, he is the biggest back in the Cougars' stable and could be the tailor-made goal-line replacement for departed Jeremiah Laufasa. "Physically, the most talented guy we've got. He's big, he's fast and he's strong. He's just got to understand the offense and he needs reps," says assistant coach Jim Mastro.
