Coach salaries -would- look like a bargain if revenue correlated with win-loss rate or quite frankly any measurable activity the coaches do. But, they don't.
IMO the guy in big-10 football who deserves a multi million dollar salary is the guy in the mascot fursuit.
The vast majority of coaches don't make this kind of money. I refuse to believe tuition is insanely high because of coaching salaries. I was actually under the (possibly incorrect) assumption that coaches salaries come largely from boosters and things like ticket sales, jersey sales, etc.
Athletics is normally (always?) a separate self-funding enterprise attached to th e university. Tutition dollars don't pay the coaches; alumni donations/gifts, sponsors, and ticket sales do.
For state colleges, they're often some of the highest paid employees in the state. [1]
