"I thought our defense at a point played well enough to win and our offense was terrible today and obviously that starts with myself," he said.
Despite putting up 32 points, the Trojans were just 8 of 17 on third down and came away empty on two red zone possessions, settling for a field goal on the opening possession.
That wasn't going to cut it against Oregon's explosive attack.
"You almost have to play perfect," wide receiver Ronald Johnson said. "They have a fast offense like they have and the hurry-up, you have to keep your defense off the field and play perfect on offense."
The Trojans also committed three turnovers, one coming as they were driving with a chance to go up by two scores.
"We felt momentum. We could feel it on the sideline but we didn't capitalize on it though," Barkley said.
Barkley also threw a pair of interceptions, throwing for 264 yards and a 5-yard touchdown to Johnson.
Kiffin also blamed himself for poor playcalling, notably on a third-down toss to fullback Stanley Havili that lost four yards in four down territory.
"It wasn't a very good call, is that what you're saying? I agree. Kennedy Pola called that, I didn't call that," Kiffin said jokingly.
On the first play of the game, Oregon linebacker Casey Matthews blitzed and found himself running into an old friend, literally.
His former Westlake Village Oaks Christian teammate, USC running back Marc Tyler, was there to try and stop him.
"It was fun," Matthews said. "I got him on that play but he got me a couple times. It was definitely fun going up against him. I'm glad he's doing well."
Tyler rushed for a team-high 69 yards and two touchdowns, while Matthews had 10 tackles and one tackle for loss for the Ducks.
"With the whole Trojan history of the Matthews family, it made it more special," said Casey, whose father, brother and uncle all starred for USC.
Defensive end Wes Horton (back) played for the first time after missing three games. The junior started against the Ducks, recording four tackles and one pass breakup.
Defensive end Nick Perry (ankle) had three tackles.
Running back Dillon Baxter (foot) only saw action on the final drive, rushing twice for fourteen yards.
Offensive tackle Tyron Smith (ankle) started and reported no ill effects after the game.
Linebacker Malcolm Smith (knee) was in uniform and warmed up with the team before the game but did not play.
Back To The Start
Kiffin said he consider going for the touchdown on that first drive after stressing for two weeks the need to finish around the goal line.
"I would have went for it, but fourth and six, the percentages are so low," he said.
Joe Houston kicked a 32-yard field goal.
There's That Man Again
After rushing for 183 yards and one touchdown in last season's Halloween night massacre at Autzen Stadium, Ducks running back LaMichael James had 239 yards and three scores on 36 carries.
"He gets stronger as the game goes along," Oregon coach Chip Kelly said. "He had a really, really good week of practice. I knew because of his week of preparation. He even felt that he had a really good week of practice." <
