One thing Caleb Williams has done absurdly well in carrying No. 4 Southern California into the Pac-12 championship game is avoid turnovers.
If the season ended today, he'd be only the third Bowl Subdivision quarterback since 2009 to throw three or fewer interceptions in 400 or more attempts, following Baylor's Bryce Petty in 2013 and Boise State's Kellen Moore in 2009.
Even four interceptions in 400 or more attempts is extremely rare. Only another eight quarterbacks have done so during the same span, including Oregon's Marcus Mariota in 2014, Louisville's Teddy Bridgewater in 2013 and two passers, Central Florida's Dillon Gabriel and Alabama's Mac Jones, during the abbreviated 2020 season.
