Though Kiffin's firing has been called for in fan circles and brewing in Pat Haden's mind for some time, the head coach was finally sacked early Sunday morning after a blowout loss at Arizona State.

Haden announced at a press conference Sunday that Orgeron, who has also been the defensive line coach and the recruiting coordinator for the Trojans since 2010, will take over as USC's first interim head coach in its storied history.

"Coach O", as he's known by the players, is the anti-Kiffin, at least when it comes to his on-field demeanor. Although both were driven recruiters, Orgeron was the most passionate and loudest voice in the locker room and on the sidelines, while Kiffin preferred to speak softly and carry a not-so-big stick.

Though sometimes seen as verbally aggressive in practice, Orgeron's brash Cajun spirit may prove to be a welcome change of attitude for the Trojans who will no longer be led by a silent and sullen ball coach.

This isn't Orgeron's first time at the helm of a major conference program.

Originally from rural Louisiana, Orgeron was the head ball coach at Ole Miss for three seasons from 2005 to 2007. He went 10-25 in Oxford and never finished higher than fourth in the SEC West standings. A defensive coach by trade, Orgeron's defenses, led by current NFL star Patrick Willis, were always stronger than his offenses. Ole Miss ranked 111th out of 117 in total offense in his first season and never truly improved.

Orgeron was fired in 2007 immediately following an embarrassing loss to in-state rival Mississippi State, in which his Rebels blew a 14-point fourth-quarter lead. 

After his lone head coaching stint, he briefly coached the New Orleans Saints' defensive line during the 2008 season. However, following the campaign, he left the NFL and went to Tennessee to coach under the newly hired Kiffin.

Orgeron has a long history with the University of Southern California. Hired in 1998 to coach the Trojans' defensive line, Orgeron found great success eventually working under the defensive-minded Pete Caroll, who of course led USC to three two national championships; Orgeron coached the first two - and undisputed - ones.

The new Trojan head coach graduated from Northwestern State University where he played defensive line all four years. Following his graduation in 1984, he went on to coach there as a graduate assistant.

From 1985 to his 1998 hiring at USC, Orgeron coached at McNeese State, Arkansas, Miami (FL), Nicholls State and Syracuse, always focusing on the defensive side of the ball.
