Hopefully you're right. But there is some merit to the "he needs to prove it" narrative.
At Oklahoma, he took over a program that was already winning. He just needed to make sure he didn't fuck it up. He showed he was able to not fuck it up.
At USC, he's taking over a program that has been floundering under a series of bad coaches and a couple of bad AD's.
Now he needs to show that he is capable of essentially rebuilding a program. We won't know that until we have a few games played.
I doubt it happens overnight but I really think Riley is the HC your Trojans have been looking for since PC went to Seattle.
