USC didn’t watch tape of the 52-42 Washington defeat.

Linebacker Mason Cobb was asked by reporters earlier this week what he saw on film and what he thought went wrong, and he responded by saying the defense didn’t look at it. “Nope,” Cobb said. “Moved on from that game.” That admission was met with frustration from both fans and former players.

Lincoln Riley was asked about the approach on Thursday. He said because of the change at defensive coordinator, they didn’t watch as much as they normally would, and he added he can count on one hand the number of times his teams have done that throughout his career.

“We’re a big (believer in) evaluate what it was, evaluate went wrong, see the good, see the bad, be very transparent about it with our players, be very transparent about it with ourselves,” Riley said. “We certainly spent time on the film and going through it as coaches.

“We didn’t completely ignore it with the players, but at the same time, with all that’s transpired and all that you’re trying to do here in a week, you’ve got to weigh that because you only have so much time with them. And I think, given the change at coordinator, going back and sitting and spending all types of time harping on that did not make the most sense to us in terms of getting this team (ready for Oregon).”

Riley said he wanted to give interim co-defensive coordinators Shaun Nua and Brian Odom a chance to “put their personality” into the plan of attack for Oregon, and he felt that would be hard to do if they were more focused on the Washington game.

“This was a situation where we didn’t completely flush it, but we didn’t spend as much time on it as we would a typical game,” Riley said.

Washington averaged 7.9 yards a play against the Trojans. Running back Dillon Johnson had a career day with 256 rushing yards and four touchdowns — completely out of left field for a team that entered the contest averaging 102 rushing yards per game.

Up next is Oregon, which has the No. 1 rushing offense in all of college football. The Ducks average a nation-best 6.3 yards per carry.
