JonArnett, a homegrown legend who starred as a running back with USC and the Rams, has died, the university announced Monday. He was 85.

One of the most elusive runners of his time, Arnett earned the nickname “Jaguar Jon” during his days dominating the Trojans’ backfield. He took over as a sophomore in 1954 and led USC in rushing (601 yards), scoring (55 points) and punt returns (129 yards), as well as interceptions (three) while moonlighting on the defensive end.

Arnett was named an All-American in 1955.
