re: SEC distributed $40.4 million to each school for the 2015-16 fiscal year

Thing about that, is that revenue from athletics is chicken feed frankly.

If you look at endowments, it is almost the inverse of your list.

A&M is by far the wealthiest school (oil lease money, though mostly residual stuff now from investments made with that money)
Vanderbilt
Missouri (Florida possibly could have a bigger endowment, would have to look it up).

Basically well heeled alumni do more for a school's bottom line than athletics. Will say the closer you get to the old industrial heartland the better finances look for schools.
