There's no question that Auburn, Florida, Michigan, Nebraska, Notre Dame, Tennessee and Texas are seven of college football's heavyweights.

Collectively, they've combined to win 26 national championships, and 21 of their players have hoisted the Heisman Trophy.

Together, they're also known for a more dubious number: $51.35 million.

That's how much money the aforementioned FBS programs have paid their former coaches to buy out the remainder of their contracts, and each of them will carry dead money into the coming season.

Buyout information for former USC coach Lane Kiffin is unknown because USC is a private school and is not required to make contract information public. According to the Los Angeles Times, Kiffin earned about $3.4 million in total compensation in fiscal 2013-14 before his departure from USC, based off tax returns.

Here's a look at some of the more notable contract buyouts in recent college football history:
