Entering the weekend, there already had been 24 coaching changes in college football, a dramatic upheaval that seems to get worse with each passing year as restless fans demand instant success. Here are the biggest moves so far:

5. Mark Stoops » He became the latest Stoops brother to run his own program -- Bob has enjoyed great success at Oklahoma and Mike was at Arizona for eight years. After three years as the defensive coordinator at Florida State, Mark Stoops gets his shot at Kentucky, a program with good fan support in the SEC but little winning pedigree.

4. Tommy Tuberville » It's interesting to see a coach leave a football hotbed like Texas Tech for Cincinnati, which appears a net loser in the conference realignment race for now. Tuberville won at Mississippi, he won plenty at Auburn -- though it was never, ever enough there -- but he was starting to feel the heat in Lubbock.

3. Butch Jones » He may not have been Tennessee's first choice, but those don't always work out anyway. Jones did a good job sustaining Brian Kelly's success at Cincinnati and now gets to reap the benefits of SEC facilities, tradition and interest at a former power.

2. Bret Bielema » It's a bizarre move at first glance considering he took Wisconsin to three consecutive Rose Bowls and is as Midwestern as they come. But Arkansas has proved willing to give its coaches the resources to win in the SEC, and Bielema gets to take advantage.

1. Gus Malzahn » This is a whole lot of faith in a man who was the offensive coordinator at Auburn when it won the national title in 2010 but has been a head coach for just one season. Malzahn led Arkansas State to a 9-3 record in 2012 and is coming home to revive the Tigers.
