Backup quarterback Tavita Pritchard led Stanford, a 41-point underdog against Pete Carroll’s five-time defending conference champion Trojans, to what was the biggest upset in college football history. With just three career pass attempts leading into his first start, Pritchard threw a game-winning 10-yard touchdown pass on fourth-and-goal with 49 seconds left. USC quarterback John David Booty had four passes intercepted, helping to end USC’s home winning streak at 35 games. The only upset with a larger point spread is Howard, a 45-point underdog, defeating Nevada-Las Vegas on Sept. 2, 2017.
