I don't doubt that, but that was a minority when compared with the entire CSU student section chanting the same during the game. As I noted, I was surprised that CU student section didn't return the favor. Too bad both student bodies don't make taking the high road the norm rather than the exception. 
What was most disgusting was the CSU (and only CSU) students throwing garbage onto other fans and the field. There is never an excuse for that type of behavior.
