Mario Cristobal has another opening on his coaching staff.

Cornerbacks coach Donte Williams is leaving after two years to become the cornerbacks coach and passing game coordinator at USC. The news was first reported by Bruce Feldman of The Athletic and later confirmed on Twitter by Williams, who is from Los Angeles.

Williams will join the USC staff headed by coach Clay Helton that includes new defensive coordinator Todd Orlando.

“This was an extremely hard decision to write and an even harder decision to make,” Williams posted. He added that “due to my father’s aging/failing health I’m lucky Coach Helton, Coach Orlando and Mr. Bohn are giving me an opportunity to come home and make a decision where I can put my immediate family first and become head of MY household.”

Williams, who is ranked as one of the top recruiters in the nation by 247Sports.com, leaves a unit that is expected to be among the best in the nation next year with senior starters Thomas Graham and Deommodore Lenoir returning along with sophomore Mykael Wright.

Williams was hired by Cristobal prior to his first season as coach in 2018. He arrived at Oregon after coaching cornerbacks at Nebraska in 2017 and Arizona in 2016.

Williams, who played at Idaho State, began his coaching career at a few junior colleges in the Los Angeles area before joining Nevada as linebackers coach in 2010. He spent two seasons as a graduate assistant at Washington before becoming cornerbacks coach at San Jose State from 2013-15.

Williams is the second fulltime assistant to leave the Ducks following the season. Offensive coordinator Marcus Arroyo was hired as coach at UNLV and replaced by former Mississippi State coach Joe Moorhead.
