USC introduced Lincoln Riley as the new head football coach of the Trojans Monday afternoon.
Riley said he has big plans for the program.
"I can promise you that you're gonna get the best out of myself, out of our staff, our players. We're gonna put something on that field that you're proud of." said Riley.
In a statement to Sooner fans, Riley said "Leaving OU was probably the most difficult decision of my life. This was a personal decision solely based on my willingness to go take on a new challenge. I'll be a Sooner fan as long as I live."
