USC's trouble with poorly timed and unnecessary penalties isn't getting better as the season goes on.
"You can't do this and win games," Coach John Robinson said Tuesday. "We went down, player by player on Sunday, and said, 'You cannot do this.' "
USC had three personal fouls and three illegal blocks among 15 penalties for 156 yards against Notre Dame.
"Our passion overcame our better judgment in some of those cases," Robinson said. "I think it was partly playing the game with emotion, and maybe some inexperience.
"I think the one that was just awful was Aaron Williams' penalty when it was third down and a million and we gave them a 15-yard penalty and an automatic first down. That one really hurt."
