Just for the record, I coach my daughter's 8th grade team and my son's 5th grade team. Caitlin has been around for 4 years now, and I can tell you I see infinitely more showboating, taunting, complaining, whining, etc. in the boys game than the girls. In fact, I can't think of a single occasion during any of my daughter's games of a girl trying to show up a ref, embellish fouls, etc. I can think of a good half dozen occasions of this happening at my son's games yesterday alone.
Thinking she's creating some legion of whiny girls basketball players is just silly and untrue. And if you are that worried about it, maybe shift your focus to the men's game/NBA because they truly are often setting a bad example for young basketball players. Makes me wonder if some of this vitriol towards Caitlin's "antics" isn't a bit sexist in nature...
