That's exactly what they did on Saturday night in front of a sold-out crowd in the L.A. Coliseum, winning 20-17.
With under a minute to play, it came down a a 47-yard field goal attempt by Andre Heidari.
The junior kicker missed his first point-after-touchdown attempt earlier in the night against the Cardinal, prompting USC head coach Ed Orgeron to attempt a two-point conversion after the Trojans second touchdown of the night; quarterback Cody Kessler completing the attempt with a pass to Marqise Lee to tie the game at 14.
But Orgeron had to go back to Heidari, this time for a game-winner and time still on the clock for Stanford to possibly attempt a game-winner of their own.
This time, Heidari came through, hitting the game winning field goal with 19 seconds left on the clock.
After the game Heidari described the Trojans game winning drive, "I'm watching the game on screen, but I'm over there kicking and getting ready," he said. "I knew they were getting them in position. I run on the field every time, look at a spot, go for a target and hit it. Every kick is the same."
To Heidari, every kick may be the same, but his teammates knew this one was different. "They all said, 'You got this'," he explained. "They believe in me."
"He made it," Orgeron said after the game. "There was a big belief on the sidelines we were going to win."
He's now 13-of-20 on field goal attempts this season.
It was Heidari's first USC-career game winning field goal and the Trojans first game winning field goal since David Bell kicked a 36-yarder to defeat UCLA in 2000.
The win improves USC to 8-3 this season.
