Freshman quarterback Nico Iamaleava ran for three touchdowns and threw for one in his first career start, and No. 25 Tennessee shut down No. 20 Iowa's Division I-worst offense to beat the Hawkeyes 35-0 in the Citrus Bowl on Monday. Iamaleava, a prized recruit for Volunteers coach Josh Heupel, stepped in for senior Joe Milton, who opted out of the game to prepare for the NFL draft. The 19-year-old threw for 151 yards, and his 27 rushing yards included three scores.
