It was late in the third quarter when, walking off a Coliseum field littered with another dropped pass, Josh Rosen made a gesture that spoke for a rivalry.
The UCLA quarterback gripped his face mask tightly, then began banging the top of his helmet, again and again and again.
He won the battle, but lost the score. He won the duel, but finished on his back.
“It’s just frustrating,” Rosen said. “Really frustrating.”
In the first and probably only meeting between crosstown rival quarterbacks with big NFL futures, Rosen was better, but Sam Darnold was the winner, the Trojans escaping with a 28-23 victory on a night of two revelations.
