"It went great," said Harper. "I really had an amazing time."
Harper talked with another Inland Empire native, and USC staff member Sammy Knight, as well as assistant coaches James Cregg and Monte Kiffin, in addition to head coach Lane Kiffin.
"They like me as a slot receiver," said Harper. "I'm a quarterback for my high school team, but I know I won't be playing that in college. But I'm a playmaker so I prefer offense."
"I'm going to Arizona State's Junior Day and I'm going to get out to UCLA during spring ball to check them out," said Harper.
Harper is planning to camp at Washington and USC as well as the Stanford Nike Camp and the Badger 7on7.
"I'm trying to get out there as much as I can so I can try and get my first offer," said Harper.
Harper said his top schools were Oregon, USC, Colorado, Boise State, UCLA and Washington.
Last fall, Harper played at Rialto (Calif.) Carter, but transferred to Colony at the semester, where he'll play his senior year.
