Will the Kansas and Iowa State fans stick around or do they only show up to support their teams?

In watching the tournament on TV I've seen a good number of BYU fans at most games but Iowa State and Kansas fans seemed to mainly be watching their own teams play.

Since the tournament moved full time to Kansas City in 2010, either Kansas or Iowa State has made the semifinals every single year. One or both schools have played in the finals every year but 2012 and 2021 (COVID issues).
