How is shouting "air ball" or "you can't do that" an insult? If someone shoots an air ball and the crowd starts chanting "You are fat! You are fat!" then we can talk. Also, having been to many HS boys basketball games over the years I can pretty much guarantee 500 people don't chant. More like 50 maybe. And it lasts all of ten seconds. I stand by my comment. All rules like this accomplish is preventing teenagers from learning how to deal with situations in which someone dares to not treat them like a delicate little flower. How many in the last 5? It's gotten worse. Much worse. Airball is the least of the problems, and the easiest line to be drawn is any chant against the opponent or any derogatory chant what so ever. Watching kids chanting against an opposing goalkeeper, "Fatty five hole" after the kid gave up a goal.... well, yeah. Again, this rule has been around for 20 years, at least in the Madison School district.
