No. 23 USC improved to 9-3 on Saturday night with a 47-29 win over Colorado.
Ed Orgeron is now 6-1 as the Trojans interim head coach.
"Good win for our team," Orgeron said after the game. "We struggled at times to get some things done, we were inconsistent with some things but we won the game and that's what matters."
Quarterback Cody Kessler finished 19-of-28 for 184 yards including two touchdowns. The first touchdown, a 20-yard toss to the end zone where sophomore Nelson Agholor was waiting, to put USC up 23-0 in the second quarter. The next, a ten-yard pas to tight end Randall Telfer in the third quarter. It was Telfer's first touchdown of the season.
Buck Allen carried the ball 21 times for 148 yards. He rushed for three touchdowns in the effort.
Fullback Soma Vainuku got in on the action, breaking for a 52-yard touchdown of his own, sealing the victory in the fourth quarter.
The only blunder by USC's offense came on the first play of the third quarter when Allen fumbled a handoff from Kessler. Colorado picked up the ball and returned it 31-yards for a Buff touchdown.
USC's 47 points were the second most scored the Trojans in 2013; they scored 62 in the win at California.
"We came out and played lights out on defense in the first half," Orgeron said.
As time wound down in the fourth, Orgeron replaced his starters, allowing for Colorado to score twice more on the Trojans' reserves.
"We made some substitutions in the third and the fourth quarter that didn't play as well as we wanted them to," Orgeron explained.
"It was huge for us, there was a lot of preparation for this week," said Orgeron. "We had an emotional game against Stanford and a rivalry game coming up, so it showed some maturity in our football team to come in here and win."
Redshirt sophomore Buck Allen was at it again for USC on Saturday night.
Allen tied his career best with a three touchdowns against the Buffaloes. In the last ten games, Allen has scored nine times rushing and has caught one pass for a touchdown.
He has 12 touchdowns this season.
Allen scored on a 12-yard carry and one-yard carry in the first half against Colorado. In the second half Allen made a move on a Buff defender, leaving him behind as he ran 23 yards for another touchdown.
Allen finished with 21 carries for 148 yards. He caught three passes for 24 yards.
Seymour goes down
Starting cornerback Kevon Seymour was the victim of a personal foul in the first quarter. He went down on the field and was tended to on the field by USC trainers.
Seymour left the game and did not return for the Trojans.
Orgeron did not have an update on the status of Seymour after the game.
Button your jacket
The forecast all week said it was going to be a cold Saturday night in Boulder, but USC didn't predict it would be a record cold.
It was 29 degrees at kickoff, making it the second coldest kickoff temperature in USC history.
"We did not address [the weather] as a team," Orgeron said. "We told the team that under any circumstances we were going to play.
"I thought it was rather pleasant tonight compared to what we had heard it was going to be like."
The Trojans kicked off in 29 degrees three previous time at Notre Dame in 1942, 1952, and 1959. Notre Dame won all three of those matchups.
It was 20 degrees in 1957 USC-Notre Dame game, the coldest in USC history and it also snowed.
Bruins ruin it for USC
In order to have a shot at the Pac-12 South championship, USC needed some help from crosstown rival UCLA – the Trojans needing the Bruins to beat Arizona State at the Rose Bowl on Saturday.
The Bruins fell behind 35-13 by halftime before mounting a comeback, outscoring ASU 20-3 in the second half – but it wasn't enough.
Arizona State beat UCLA, 38-33. The Sun Devils are the Pac-12 South champions and will play Stanford in the Pac-12 championship game.
"I didn't even check it out," Orgeron said. "That's not something we were targeting. Our objective was to beat Colorado. Next week our objective is to play really well and beat UCLA."
UCLA also killed its own chances at the Pac-12 South title with the loss.
