I'm hopeful that AD's will start to realize they aren't going to be able to sell out games charging $100 per ticket in the near future. They need to understand that, as little as only 20 years ago, people HAD to attend the games to watch every one of their school's games. If you didn't buy tickets, you weren't sure until the week of the game whether it would be on TV or not.
College football has transitioned from an event that most people experienced in the stands to an event most people experience on TV. I hate watching empty stadiums for the sake of squeezing profit out of the fan base. Each one of those empty seats represents a future fan the AD has chosen to price out in many cases.
I'm speaking specifically to Iowa at this point, but I remember two years ago when Iowa played PSU in a night game in Kinnick, that game didn't sell out. 10 years ago, the idea that a home night game against a top 5 opponent wouldn't sell out was laughable. The demand was there to be at the game, but charging $100 for nose bleed seats in the end zone (especially for families of 4+) makes staying at home and watching on TV look more attractive.
I know Iowa sold out pretty much every home game from 2003-2012 (ish, going from memory). Then in recent years single game ticket prices have continued to go up and sell outs have continued to go down.
