USC Coach Lane Kiffin on Saturday officially announced the addition of three new assistants and the promotion of quarterbacks coach Clay Helton to offensive coordinator.
The news release sent out by USC did not address whether Kiffin would give up play-calling duties.
"I am excited to have completed the reconstruction of our staff," Kiffin said in a statement. "It was a very exhaustive and thorough process."
Helton will continue to coach quarterbacks as the Trojans transition from four-year starter Matt Barkley to sophomores Max Wittek or Cody Kessler or freshman Max Browne.
Former running backs coach Kennedy Pola, who was fired two weeks ago, held the title of offensive coordinator for three seasons. But Kiffin oversaw the offense and called plays.
