During the 2000's, Big 12 programs made several hires from SEC coordinators that were odd.
Texas pulled Cheezit from the barn after the 2004 season, he was part of their BCSNC in 05, and then he left after the 06 season to take over at Iowa State.
Will Muschamp was the DC at the barn during the 06-07 seasons and then took over the DC position at Texas for the 08 season.
Bo Pelini had come from the Big 12 to take the DC posltion at LSU and then returned to the Big 12 as the Nebraska HC for the 08 season.
Chizik was a total failure at Iowa State, which obviously made him highly-sought for the barn's HC position when Tubberville left.
Muschamp hung around Texas like a vulture in-waiting for Mack to bow out, finally got tired of waiting for the carrion, and took the HC at Florida after Urban's gut exploded from being processed badly in two straight years. Things aren't looking great for him right now.
Pelini's not a fan favorite either after his publicized tirade and several mediocre seasons.
Bob Stoops was hired in 1999 from his DC position under Spurrier at UF and has been very successful at OU, even though he only has the one NC. Multiple other hires of coordinators and head coaches from the SEC followed and most of them ended in failure for those Big 12 teams. Franchione slithered out of Alabama to much fanfare in College Station, took one of the worst shellackings of modern history from the Sooners, embodied the term mediocre while at aTm, and then disgraced the program with his exclusive newsletter scheme. Tubberville came to Texas Tech after Craig James buried a slaughtered hooker and Mike Leach, had a decent record there, but bolted for Cincinnati a couple of years ago. Charlie Weis was hired just a couple of years ago after a one-year stint as Florida's OC and although he fits Mangino's leftover wardrobe nicely, he hasn't provided much of a decided schematic advantage for the JayHawks. Add these cases to those mentioned above and it's no wonder that the Big 12 doesn't like the SEC. Coaches that do well in the SEC go to die in the Big 12 in most cases.
