That, incredibly, was also the game in which RU knocked USC out of the national championship game. The pairings for the NC game relied heavily on computer rankings back then and those computers took SOS into account. But they also took into account the SOS of all of your opponents' opponents. And that is where RU defeating SU comes in. As noted in one of the articles linked here, the week after the 24-7 win over SU, the Orange hosted ND at the Dome. They upset the Irish (probably saving Pasqualoni's job for one more season, which was also good for RU since, by firing him in 2004 rather than 2003 is what gave Ray Rice to us). The Irish were one of the biggest, if not the biggest win on the Trojans' schedule. So when SU upset the Irish after losing to RU, that cost USC enough points that it ended up 3rd in the computer rankings that season, despite being unbeaten. IIRC, the NC game was between Oklahoma and Auburn who were also unbeaten.
