You guys are killing me today. So are you seriously saying that the University shouldn't try to reserve seats for people that buy season tickets? Really? That's the most ridiculous thing I've ever heard.
However, suggesting that they only ask that those seats be left open through the 1st quarter and then allowing anyone to sit there is a reasonable suggestion.
Season tickets don't cost much now, but I don't think most people that buy season tickets with reserved seats on the 50 yard line would be too happy to show up and find out that a bunch of people that decided to come out for their 1 game for the year had taken all the best seats.
I don't think opening up seats in the first 25 rows 40 to 40 is going to change anything at all in regard to the number of people coming to games.
I can understand that someone might be frustrated if the ticket staff told them all seats are general admission if there actually some reserved seats. However, the answer here may be as simple as making sure all the ticket staff sets appropriate expectations at the gates.
I've not seen an usher checking ticket stubs once the game is underway to keep people out of seats (not to say it doesn't happen, but I haven't seen it).
