Predicting 8k still seems a little wild. That would mean over 10% of the crowd is KU fans, and over 20% of your home sellout crowd is in attendance.lol, that's crazy. I do think you see a good group though. Between 5K to 8K more than likely. Chicago is the 2nd largest KU alumni base. I know a lot of KU fans in Chicago who are going to the game.
Oddly enough, KU football fans tend to travel fairly well. Yet we struggle to sell out our 50K stadium every week. The fanbase isn't huge, but there is a dedicated contingent of hardcore KU football fans who have stuck it out over the bad years and travel a lot. But predicting 20K is crazy.
I think 3k-5k sounds reasonable but man that would be nuts if you guys had that much.
