On the plus for the AD, when the stadium was expanded all former athletes were sent a letter of interest. If they responded they were allowed to purchase two season tickets. With or without donations. Honestly the donation didn't have an impact. I have a buddy that gave a couple hundred bucks and his seats are right next to mine.
I don't think there is a good or fair solution to encompass everyone, It is what it is.. I think Ohio State is experimenting with some intersting ways to distribute tickets?
