The moves come as Clay Helton shakes up his staff after a 5-7 season that saw significant pressure upon USC’s administration to fire the head coach. USC AD Lynn Swann opted to retain Helton with the understanding significant changes will be made from 2018 to 2019.

Trojans defensive line coach Kenechi Udeze also announced Tuesday he will not return. Quarterbacks coach Bryan Ellis has also left to become the offensive coordinator on Tyson Helton’s staff at Western Kentucky, meaning four of Helton’s 10 assistant spots have now turned over.

Martin was stripped of play-calling duties mid-season as Helton looked to shake up the Trojans’ struggling offense.

“Tee and I have had conversations about this decision, and he was supportive,” Helton said at the time. “He has done a tremendous job here. He will stay involved with the offense as he remains the offensive coordinator, helps put together our practice and game plans, and serves as my offensive eyes during games.”

USC was 4-4 before the change and 1-3 after.

In changing quarterbacks from No. 3 overall pick Sam Darnold to true freshman JT Daniels, USC slipped from 13th to 84th nationally in yards per play from 2017 to ’18.
