Projected starter: Keaontay Ingram, Sr.
You don't bring in someone like Ingram if you're not prepared to hand him the starting job. Sure, he'll have to prove better than the competition, but he had two 700-yard rushing seasons at Texas and boasts a proven pass-catching skillset.
Rotation player: Vavae Malepeai, RS-Sr.+
Malepeai is still USC's most trusted back until someone knocks him from that perch. He'll get regular playing time unless injuries get in the way.
Rotation player: Stephen Carr, Sr.+
Trojan fans have been waiting for ages to see Carr healthy and rolling. Maybe 2021 is the year? He'll be sharing a backfield, but he can do more than he's shown so far.
Rotation player: Kenan Christon, Jr.
Christon's speed remains unique among USC skill players. The crowd of more-veteran options ahead of him is a major hurdle to clear, though.
Redshirt: Brandon Campbell, Fr.
Campbell is enrolling early, so he'll be able to integrate himself into the running back corps this spring. There are just too many able rushers ahead of him to expect much in Year 1. Injuries could always thrust him into a starring role. He'll have to be ready.
