It was a disappointing start to Pac-12 play for USC, which lost to Colorado, 72-62, at the Galen Center.
Evan Mobley struggled and made only 5 of 14 shots. He finished with 12 points. The Trojans trailed by as many as 15 points in the second half.
USC (5-2, 0-1) had its nine-game winning streak at the Galen Center snapped.
The Trojans have lost five straight to Colorado. Coaching matters.
