Using 2019 revenue (since 2020 is the weird COVID year that had some strange effects)
2019 Conference Revenues (in millions of dollars)
1 |
SEC |
$1921 |
2 |
Big 10 |
$1859 |
3 |
PAC12 |
$1032 |
4 |
Big 12 |
$989 |
5 |
ACC |
$920 |
6 |
MWC |
$576 |
7 |
AAC |
$465 |
8 |
C-USA |
$456 |
9 |
MAC |
$409 |
10 |
Sun Belt |
$356 |
So the current gap between the Big 10 and the Big 12 is $870M. The current gap between the Big 12 and the MAC is $570M. And that's not even accounting for the Big 12 losing its two primary draws. For all the talk about P5, the SEC and BIG10 are in a world of their own financially, with the PAC, Big12, ACC then grouped together in a completely different tier.
