Of course, basketball isn't enough of a draw at PSU to make that work. Nor any other sport (I'm sorry Wrestling, women's volleyball, etc - they aren't that popular to make a difference). Ice hockey is the only one that might work in that aspect but does student tickets sell out quickly or at all there?
I think the potentially way to work that is the reverse - you get points for attending non football sports and this gives you a point total that either allows you to automatically get football tickets or gives you a higher weight for the lottery. This creates a way for lesser sports to get more student support while providing a way for "superfans" to be likely to get tickets.
