One mentioned that they were #13 the previous year.
But this is the price of tickets being resold on StubHub and the like. It is a measure of something, but more interesting would be the "actual" average price of tickets in a stadium. I use quotes because there is the ticket price and then the price of joining the booster club, which is a requirement for buying good tickets.
I think I've seen that list. I think it was in an article about BYU's ticket prices. Google didn't find it for me.
