Looking at it, I see that it's $300M/yr for 15 football games each season. So an average of $20M per game (plus they get some basketball games)
Which is just insane to me, but means I was mistaken. Good for the SEC I guess.
My initial point still stands that I haven't seen any evidence that BYU's ESPN deal gets them $15M/yr. If there's data or links to support it, I'm absolutely happy to change my view, but best evidence I've seen has it at $4.5M (admittedly that's 2019, last non-COVID year, and things may be better going forward)
