This is a really interesting idea. I do think we should ditch the pride of the "largest student section in the country" if students continue to be content with sitting at Kilroy's when they don't feel like making the walk in the cold.
I'm not sure turning people away at the door would work, but I do think it'd be smart to reduce to # of student tickets for games that aren't Purdue, MSU, big home matchup in B1G/ACC Challenge, etc.
Logistically possible? No idea. But it's embarrassing when Assembly Hall isn't even close to full for the Maryland game.
