Utah St. 31, Colorado St. 19

FORT COLLINS, Colo. -- Kerwynn Williams set career highs with 21 carries for 205 yards and two touchdowns in leading Utah State past Colorado State 31-19 Saturday night. Williams, a senior, had touchdown runs of 26 and 58 yards. His only other 100-yard game came in 2010, when he gained 147 yards on 19 carries against Boise State. The Aggies (3-1) are off to their best start since winning their first five games in 1978. They've outscored their opponents 51-0 in the first quarter and haven't given up a touchdown in the first half. They led 17-0 at the break, and it could have been much worse. After Williams' 26-yard TD run, the Rams (1-3) had a goal-line stand, and Utah State settled for Josh Thompson 's 20-yard field goal. The Aggies needed 19 plays to cover 85 yards on their next score, capped by Chuckie Keeton 's 1-yard fade pass to Matt Austin on fourth-and-goal from the 1.
