BOULDER — Brenden Rice was up early Saturday morning. Technically, everyone on the USC football team was. The Trojans had to play a game at 9 a.m., Los Angeles time, against the Colorado Buffaloes. But this was a different deal for Rice, who was one of Colorado’s best players in 2021 before leaving the program to join Lincoln Riley, Caleb Williams & Co. “I was up an hour earlier, went to work out and burn off some steam because I wanted to come in here and I kind of had butterflies,” Rice said after USC’s wild 48-41 victory.
