Southern California hired Clay Helton as its football coach Monday, removing the interim tag after he guided the team to a division title since taking over for Steve Sarkisian.
Athletic director Pat Haden announced Helton had signed a multiyear deal.
"After weeks of searching the collegiate and pro ranks, interviewing candidates, and speaking with head coaches, athletic directors, NFL executives, and very knowledgeable football people, and after observing Clay in action the past seven weeks, it became abundantly clear that what we were searching for in a coach was right here in front of us," Haden said.
The 43-year-old Helton has been an assistant with USC since 2010, working under both Lane Kiffin and Sarkisian.
He was offensive coordinator when Sarkisian was fired on Oct. 12. Sarkisian acknowledged he was struggling with alcohol after he went on an obscenity-laced rant at a booster function before the season and the coach and team continued to struggle for the first five games.
The Trojans have gone 5-2 since Helton took over and beat UCLA on Saturday to clinch the Pac-12 South and a spot in the conference championship game. The Trojans (8-4) will face Stanford on Saturday.
Haden said beating UCLA was not the reason Helton was hired.
"He was not hired because many current and former players voiced their support for him. And he was not hired because he is a Trojan. He is our choice because we believe he can win Pac-12 and national championships here. Clay Helton is the right man at the right time for the USC football program," Haden said.
