This would be the end of the rivalry.
Who wouldn't love to kick out their biggest rival? Kicking out Kansas would be the biggest power Kansas State could have. It would not affect them too much in terms of football because the WIldcats dominate on the field, but it would make basketball a lot easier.
With how dominant the Jayhawks are on the hardwood, giving them the boot out of the Big 12 would be so much fun. The Big 12 would actually have a different Big 12 champion in basketball every season.
