USC head coach Clay Helton announced several staff moves on Monday afternoon:
* Tee Martin has been relieved of play calling duties but will retain the title of offensive coordinator and will continue to be involved with game planning, coaching the wide receivers and recruiting. Helton will take over play calling duties.
* Neil Callaway is no longer the offensive line coach for the Trojans. He is a longtime Helton family friend who Clay has referred to as a second father.
* Tim Drevno, currently the RB coach/run game coordinator, will add OL duties for the remainder of the season.
