A pair of Heisman Trophy winners were further cemented into Southern California’s legacy Thursday, as the Trojans retired quarterback Caleb Williams’ No. 13 jersey and running back Reggie Bush’s No. 5.The program revealed Williams’ jersey retirement on a social media video that featured music artists Snoop Dogg and John Legend along with USC coach Lincoln Riley, Trojans women’s basketball star JuJu Watkins and a host of Williams’ teammates.Williams became USC’s eighth and most recent Heisman winner when he threw for 4,537 yards and 42 touchdowns in 2022, his first year with the Trojans. The eight Heisman Trophy winners are the only Trojans to have had their numbers retired. Williams was drafted first overall by the Chicago Bears this April after piling up 8,170 passing yards and 72 touchdowns against just 10 interceptions in his two seasons at USC.Bush had his number retired for the second time. USC removed his number in 2010 following NCAA sanctions against the program involving Bush, who received improper benefits during his tenure with the Trojans.
