New USC coach Lane Kiffin has plucked a fourth assistant coach from his former staff at Tennessee.
Willie Mack Garza, the Volunteers secondary coach last season, will join Kiffin's staff at USC, though his specific duties won't be announced until the staff is complete.

Garza's hiring brings into question whether long-time USC assistant Rocky Seto will be retained by Kiffin. Seto was promoted to defensive coordinator last year after Nick Holt left for Washington and also oversaw the secondary.
Chris Low reports on the SEC blog that Garza's departure may have been abrupt.
Kiffin has hired his father Monte Kiffin, Ed Orgeron, James Cregg and now Garza away from Tennessee.
