BOISE -- Boise State scored on its first offensive play Saturday and never looked back in a 42-14 victory over Colorado State.
Senior D.J. Harper went untouched on an 80-yard touchdown run, and the Broncos (9-2, 6-1 Mountain West) scored on five of their six first-half possessions against the Rams (3-8, 2-5) to keep their conference title hopes alive. Boise State entered the day tied with Fresno State and San Diego State in the Mountain West.
Harper, a sixth-year senior playing in the final home game of his career, finished with 107 yards rushing and two touchdowns. Quarterback Joe Southwick completed 17-of-20 passes for 216 yards and two touchdowns in a little more than one half of action.
Colorado State trailed 42-0 when it finally scored on a career-long 72-yard run by Chris Nwoke with 2:09 in the third quarter. The Rams managed only 229 total yards and had three turnovers.
