What he did at the end of the USC/UCLA game was nice. Before this play, USC took a knee, but UCLA then called a timeout. In response, this happened:
Pete Carrol was trying to end the game, but UCLA coach Rick Neuheisel didn't want it to end. Personally, I would've simply passed for a 1st down, or maybe ran the ball (UCLA had 2 timeouts remaining). But Neuheisel invited the touchdown pass.
But Pete Carrol's sideline celebration looks like a 12 year old girl at a Jonas Brother concert.
