Is that the most that goes to a NFL game? College football will fill multiple 90K+ seat stadiums every Saturday. It basically comes down to however many home games there are that Saturday for Michigan, Penn State, Ohio State, Texas A&M, LSU, Tennessee Vols, Texas, Bama, and Georgia. At that's just the ones that seat 90K or more. There are plenty others above 60K that fill up virtually every home game.
Some Div-III schools have 60k seat stadiums.
Mount Union is one, I think.
It may only be 60K seats, but you can bet your sweet a*s, it generates way more revenue with “boxes” and cost of adult refreshments.
