Castille first aided Nebraska as a true freshman as a power back in short-yardage situations. He dropped more than 15 pounds before his sophomore season which allowed him to refine his all-around skills and show the ability to be an every-down back in the Husker offense. He gained nearly 500 yards on the ground last season, capped by his best career performance in the Gator Bowl victory over Clemson.
Castille carried six times in each of the first two games, with a touchdown against San Jose State. In the opener against Western Michigan, he had a career-high 38 receiving yards on three catches, including a career-long 31-yard catch. He rushed 10 times for 75 yards in a 38-7 win over New Mexico State. Castille bulled his way to 70 yards and a touchdown on 11 carries at Iowa State. He added 49 yards on five carries against Kansas and six carries for 51 yards and a score at Kansas State. Included in his effort at KSU was a then-career-long 37-yard touchdown run on a 4th-and-1 play in the first quarter. He capped the regular season with 12 carries and his sixth touchdown in the 40-31 victory over Colorado.
