Should be a yearly rivalry game. This is the best story of the tournament if Wichita State wins this. Well deserved.
From Bill Self's perspective I can understand why he wouldn't, by making it a rivalry game it would end up on TV and give more exposure to Wichita State. You'd make the other viable option in the state an even more attractive destination for prospects since they'd have a yearly game vs KU which would no doubt be on ESPN.
If I'm KU, I don't do the game cause it makes the WS program stronger and could pull more players from that region and shrink your talent pool.
