GREENSBORO, N.C. (AP) — -

Bobby Petrino turned Louisville into a top-10 team nearly a decade ago. Now, more than two years after a scandal derailed his career, Petrino is back with the Cardinals as they enter the Atlantic Coast Conference.

He said Monday at the ACC's preseason media days that he will handle things differently this time around.

Petrino said he must "prove to myself and everybody else on a daily basis" that Louisville made the right decision in bringing him back.

Petrino left Louisville in 2007 to coach the NFL's Atlanta Falcons for less than one season before going to Arkansas. Then he was fired in 2012 after a scandal involving a motorcycle accident with his mistress as a passenger.

He coached last season at Western Kentucky.
