Last year, Caleb Williams became the eighth USC player — and third quarterback — to win the Heisman Trophy. Running backs Mike Garrett (1965), O.J. Simpson (1968), Charles White (1979) and Marcus Allen (1981) were the first Trojans to hoist the Heisman. Then USC produced three Heisman winners in a four-year span: quarterbacks Carson Palmer (2002) and Matt Leinhart (2004), and running back Reggie Bush (2005). Bush's Heisman was later vacated for NCAA rules violations.
