LOS ANGELES (AP) -- Southern California coach Lane Kiffin has hired three assistant coaches to complete his staff overhaul after the Trojans' disappointing 7-6 season.
USC added Mike Summers, Tommie Robinson and Mike Ekeler on Saturday night.
Kiffin parted ways with offensive coordinator Kennedy Polamalu and defensive guru Monte Kiffin, his father, after the Trojans' fall from a preseason No. 1 ranking to an embarrassing Sun Bowl loss.
Summers will be the Trojans' running game coordinator and offensive line coach. Robinson is the Trojans' passing game coordinator and running backs coach, while Ekeler is the new linebackers coach.
Kiffin also shuffled assignments among his current coaches, notably giving the additional title of offensive coordinator to quarterbacks coach Clay Helton. Kiffin runs the Trojans' offense himself.
Clancy Pendergast was named USC's new defensive coordinator earlier.
