This is what fans do when things aren't going well. Heck, I remember stepping up to the plate in little league baseball and having some parent in the stands say in a loud, sarcastic voice, "Watch this kid strike out again."

By the time you get to college, you should expect that people are going to criticize poor play, and the coaches are paid professionals. If they're not getting the job done, they're going to hear it from their customers, the fans.
