I cannot stand "there isn't an advantage" statement. If my pitcher is working to keep her foot down as part of the rules, so should yours.
Even in the younger ages that I deal with, I see it. They might be throwing bullets but when they are made to keep the foot down, they are not quite as fast or as in control.
At a Utrip tourny this weekend, one of our pitchers had started skipping/leaping. PU on field came to fence between innings and asked UIC if she was skipping and he said, " yeah but she is 10, let it go" what??
Enforce the rules, or change them. Don't make up your own as you go! Grrr!
While I agree that it does indeed provide an advantage, especially in the case of someone like Barnhill the argument is moot. It is kind of like parking in a handicap spot and claiming it is ok since there were plenty of other spaces available. If it is illegal, it needs to get called advantage or not. Claiming that it provides no advantage is just a lame by those attempt to rationalize it not being called. In the case of the UIC you have to wonder what else they are willing to let slide.
