There is another side to this that I have seen. Now and then kids get a little big for their britches. I was coaching rec ball last summer, a girl on the team had some cousins who were on a local team that won some state titles a few years back, they wanted to help out so I had them on the field with us any time they could make it.
One of them was doing soft toss before a game and a girl stepped up a little too close to her, she almost hit her with her first swing. She asked the player to move her feet so that she didn't get hit in the side of the head. I saw the whole thing happen and could tell the player was annoyed. The coach tossed her 8 or 10 more balls and didn't get her head caved in, the player got to swing her bat. Win/win, right?
Nope. The player walked directly to the dug out and told everyone how much she hated the coach. She was telling HER how to swing her bat. She is a travel ball player, she knows what she's doing, etc, etc.
