When Mike Leach brought the Air Raid offense to Norman in 1999, it didn't take long for splashy results.
The system revitalized a moribund Oklahoma program, turned Josh Heupel into a star and quickly started its migration throughout the Big 12 and college football, sparking the Clone Wars.
It took just a year after Leach's arrival — with Leach himself having moved on to a head coaching job at Texas Tech — for the Air Raid to break through and win a national championship when the Sooners went undefeated, beating Florida State in the Orange Bowl to give OU its first title since 1985.
