I disagree. When I was a student at Iowa State I knew a number of other students that were more hawkeye fan than Cyclone fan. They still got season tix to both basketball and football and went to the game and would root on the Cyclones as long as they weren't playing the Hawkeyes.
I'm not saying whether this is right or wrong, what I am saying is that there will be hawkeye fans that "get" tickets without much difficulty because they will already have tickets from being a season ticket holder. Hilton could still be rocking, but it might take a hit this game.
It's not just this rivalry, it's any in-state or border battle rivalry. K-st vs KU, Mizzou vs KU (when it happened) is similar, Packers vs Vikings always has a good chunk of both fans at either game, Packers vs Bears, Cubs vs White Sox, Yankees vs Redsox... it's a reality. When both fanbases are so close physically together, there will be a mixture of fanbases that attend the games.
This is neither here nor there though, I think we will be 17 in AP and 21 in Coaches.
