I don't know if this is when stuff happened, but leaving the stadium from the northwest after the game was a nightmare. The exit is already bottle necked due to the construction. Iowa's band took that route to leave too and took up a large width of the already small pathway. The entire time the band was marching through there, they were doing their typical chants, and playing songs, including the Iowa fight song. Then they had to cut across the crowd trying to leave to get to their buses making 5,000+ fans wait for them to cross. All this after fans just spent almost 7 hours in the stadium to sit through a frustrating loss. So I can see how some people might have been annoyed at having loud instruments blown in their face by the opposing teams band and might have said something.
