Source: Hawaii hires ex-USC assistant

Former USC assistant Gib Arnold, who was not retained by head coach Kevin O'Neill, has been tabbed as Hawaii's head coach.

According to a source close to the situation, Arnold -- who graduated from Punahou School in Hawaii and is the son of former Hawaii coach Frank Arnold – was hired on Saturday.

Saint Mary's assistant Kyle Smith was also in the mix for the opening to replace Bob Nash -- who was 34-56 in three years after replacing Riley Wallace.

Arnold, 40, has been an assistant at USC, Pepperdine, Loyola Marymount and Vanderbilt. He was also the head coach at the College of Southern Idaho -- a junior college.
