Illegal or Legal, what are your stipulations?

[Coachtindell]

I attended a 12U state tourny 2 weeks ago and every single pitcher on the 4 fields I observed for 2 hours left contact with the ground for anywhere from 4 to 12 inches. You had to really pay attention to see some of them, but it happened.

My daughter developed this about 2 weeks ago and I debate how much emphasis I need to put on it until season end as no one is calling it.

So I am interested to hear your responses.
