Might not be so far off. I think conference revenue is at the bottom of the chart in non program specific.
They had 7 home games in 2024, averaged 108k fans, so that's 750k tickets sold. Given that Ohio State was on the schedule, I bet the average ticket price was at least $150. That's $112M in ticket sales alone.
Throw in parking and concessions for 7 games, you may end up close. I don't know where they record donations, but I would imagine they get a **** ton of those too.
It's good to have a huge stadium that people will fill and pay a lot to get into.
