this is 2018 but I think this is the only stat you need ::

FootballScoop has obtained financial data for every FBS program through the U.S. Department of Education. As required by the Equity in Athletics Disclosure Act, we're able to sort sport-specific data for every school in the country. (Well, almost every one. Privates such as Notre Dame and USC had data available, but select schools like Connecticut and Temple were not present.)

Texas, unsurprisingly, led the nation by a wide margin by a whopping $33 million. The Longhorns have maintained their lead despite enduring the program's worst decade since the 1950s. UT's revenue has more than tripled since 2003, the earliest year data is available, when they led the country with $47 million in football-specific revenue.

The data below covers Fiscal Year 2018, running from July 1, 2018 through June 30, 2019. And, we should add: bean-counting at the college level is always tricky because accounting practices are not standard across the industry.

Without further ado, here is the latest data according to the U.S. Department of Education.

Power 5 -- Top 15
1. Texas -- $156 million
2. Georgia -- $123 million
3. Michigan -- $122 million
4. Notre Dame -- $116 million
5. Ohio State -- $115 million
6. Penn State -- $100 million
7. Auburn -- $95 million
8. Oklahoma -- $94.8 million
9. Alabama -- $94.6 million
10. Nebraska -- $94.3 million
11. LSU -- $92 million
12. Tennessee -- $91 million
13. Wisconsin -- $90 million
14. Florida -- $85 million
15. Washington -- $84 million
