Billy Donovan left Florida for the NBA, but college coaches leaving for bigger paydays in the richest professional league in the world is no longer as big of an issue.

Elite college coaches like John Calipari and Mike Kryzyzewski make $6 million to $8 million per season.

There are a host of college coaches several tiers down that make $2 million per season.

Wichita State, a school in the Missouri Valley Conference, recently gave Gregg Marshall a raise to $3.3 million per season.

That's more than what the current head coaches of playoffs teams such as the Washington Wizards, Portland Trail Blazers and Toronto Raptors earn per season.

When Donovan was going to leave Florida for the Orlando Magic in 2007, it was for a $5 million per season salary, which was a rarefied strata at the time.
