From the locker room: Coach O 'proud'

SOUTH BEND, Ind. -- Notes, quotes, and anecdotes from Notre Dame Stadium after the Trojans (4-3, 1-2 Pac-12) lost to Notre Dame (5-2), 14-10.

USC interim head coach Ed Orgeron comments

Painful: "Well, we have a hurt team in there. They gave it everything they had. I was really proud of our football team and our players and our coaching staff. Game two of a new season, the way we competed to the very end."

Yellow and red: "Obviously the penalties hurt us tonight in crucial situations, and we didn't punch it in the red zone when we needed to. It seemed that every time we had a first down or something like that, we had a holding call or jumped offside. We shot ourselves in the foot, and then it was second and 20."

On Notre Dame defensive success: "Pressure. A lot of pressure. That was a good front. We knew it was a good front coming in, a lot of pressure, and we just seemed that we couldn't get things going. Those are big guys to block, 300 (pounds) in the middle."

On the offensive line: "Hey, listen, we made some mistakes. We didn't do the things we would like to do at a high level, but I am proud of all my guys, just like my family. They fought as hard as they can and gave it everything that they can."

Notre Dame head coach Brian Kelly comments

On beating USC: "They found a way to win the game. Our defense was outstanding in the second half and gave us a chance to win the football game. Great win, one that obviously when it comes to beating USC will go a long way with our guys."

On defensive lineman Stephon Tuitt: "He got the game ball. He was all over the place. They (USC) couldn't handle him today. If you're wanting to talk about a defensive lineman that was dominating, you could throw that word out there. He was a force out there."

On defending Trojans wide receiver Nelson Agholor: "I thought we defended well. If he was going to hit us on some drive routes and some intermediate routes, we were going to rally and tackle him, and that was the extent of it."

The offensive scoring average: The Trojans scored 10 points against Notre Dame. Prior to the game with the Irish, the Trojans were averaging 28.0 points per game.

Trojans quarterback Cody Kessler comments: "It really sucks that we lost, but we gave it a good effort. As a team, we wanted badly to win it for Coach O and the coaching staff. We have nobody to blame but ourselves. We just have to eliminate the mistakes we're making as a team."

Offensively better: Before the Notre Dame game, the Trojans were averaging 408.0 yards per game in total offense. Against the Irish, the Trojans had 330 total yards on offense.

Kessler: "Not taking away anything from Notre Dame, we have to execute, and we missed too many assignments and were dropping balls. It's disappointing, but stuff that can be fixed, and we have to eliminate the penalties. We put ourselves in too many third and long situations."

Grafting an answer: On his line's offensive penalties, starting senior right tackle Kevin Graf said, "I was definitely surprised (by the penalties). Honestly, I thought a lot of our guys were pretty angry about those calls, but we'll see what the film says. It's very frustrating. Someone like me who it's their senior year and this is the last time I'll get to be in this place. It's very upsetting."
