Lane Kiffin (3) at both Tennessee and USC. When: 2009 at Tennessee, 2010-Sunday at USC. Why: Deserter in Knoxville; inept in Los Angeles; unlikeable at both. Was it an obvious mistake beforehand? For sure the second time, and a dicey fit the first time. Kiffin actually provided a brief blip of sunshine with the Volunteers, leading them to their only winning season since 2007. But at 7-6, he was barely worth all the headaches he caused and then he fled to USC and really ticked off the Big Orange faithful. The Trojans' 2012 flop from No. 1 to 7-6 was among the worst in recent memory.
Derek Dooley (4) at Tennessee. When: 2010-12. Why: Gene pool didn't carry much weight come kickoff. Was it an obvious mistake beforehand?
To everyone outside the Volunteer State. Dooley went 4-8 the previous year at Louisiana Tech and had a 17-20 record overall there. At Tennessee, he went 0-15 against ranked opponents; gave up 40 or more points nine times; and lost to perennial whipping boys Vanderbilt and Kentucky the latter of which played a wide receiver at quarterback all game.
