After breaking his leg in the very first game of the 2007 season at Oregon State, Asiata returned in 2008 and played in all 13 games with one start. He led the Utes in carries with 146, rushing with a career-high 707 yards (4.8 ypc and 54.4 ypg) and touchdowns with 12, which tied for second-best in the Mountain West Conference. He also had 13 receptions for 111 yards and one touchdown and completed 2-of-3 passes out of the "Asiata Formation," with both completions going for touchdowns. His biggest outcome of the season came in Week 4 against the Air Force when he had 19 carries for 116 yards. Other big games included 85 yards against New Mexico on November 1 and 83 against San Diego State on November 15. The Utes went undefeated, going 13–0, and went on to face Alabama in the 2009 Sugar Bowl. The Utes won the game and created controversy over the fact that the Utes were not in the BCS Championship Bowl that was played between two teams with 1 loss each. At the end of the season, Utah was the only remaining undefeated team in the country and was ranked #2 on the Associated Press (AP) Final Poll. 2009 season In his sophomore season, Asiata played and started in four games before breaking his leg during the game against Louisville. Prior to the injury, he was averaging a league-leading 101.3 yards per game and his four rushing touchdowns also led the league at the time. He finished with 74 carries for 330 yards (4.5 ypc) for an average of 82.5 yards per game and also had nine receptions for 88 yards. In the season opener game, he carried the ball 36 times for a career-high 156 yards against in-state rival Utah State. His 36 carries tied the fourth-best single-game total in school history. The following week, he had 94 yards on 20 carries against San Jose State. 2010 season In his junior season, Asiata played in all 13 games, starting seven of them at running back. He rushed 155 times for 695 yards (4.5 yards per carry). His average of 53.5 yards per game ranked ninth in the Mountain West Conference, while his nine total touchdowns (eight rushing and one receiving) tied for ninth. In Week 6, he had Utah's only 100-yard rushing game of the season with a 109-yard performance against Wyoming.
