Last season, the USC receiver saw limited playing time in a position group that boasted several playmakers.
Imatorbhebhe, whose brother Daniel is a tight end for the Trojans, has caught two passes for 11 yards since arriving from North Gwinnett High in Suwanee, Ga. in 2016.
"His natural ability and explosiveness is off the charts," coach Clay Helton said. "He's a special talent that is really coming into his own."
Imatorbhebhe demonstrated a knack for gaining yards after the catch when he took a short pass and turned it into a long gain.
