I think Saban was paid around $9 million when a reporter asked the Alabama President how they justify paying a football coach over $9 million a year. He said that's easy, upon Nick Saban's arrival in Alabama our revenues are up over $100million! Also, the TV contracts are paying big bucks to all conference programs now. And winning coaches sell a lot more team merch!
For CEO's in big corporations, salary is small and incentives are stock price related and performance based. Most income is from stock options, not salary. In football its wins but you pay up front to get the performance.
