Kansas is not just going to have 10k fans.....they are averaging 43k fans per game at Arrowhead, and the only two opponents they've hosted are TCU and Houston....two fan bases not known for traveling.I don't think they are pricing out their fan base. I'd guess the KU football fanbase is price insensitive - and really small. So they're only going to get 10k fans, regardless of price.
I'm not sure where our fans are getting the 10k fans thing from....yeah the KU fans of old for sure, but they'd love to play spoiler and Iowa State is at least a bigger name to Kansas fans than TCU or Houston
