Sounds like you need an economics lesson. Demand isn't created out of thin air. Neither you nor SDSU can sell out your stadiums, nobody can but NDSU. If all these goofy tricks everybody does to keep the only people willing to buy those seats ends up screwing you in the end, so be it.
Look at UNI, they jacked the prices up so high, they were 3/4 full for the NDSU game. I never planned on going so I have no stake here.
