Parents get over yourselves, let's face it a player has to do in the end what's best for them personally. Unless someone is going to pay for your daughters education do what is best for her.
If you go to buy a car and you get a toyota, and you agree to buy it, if you find a better deal somewhere for example someone will give you a brand new bmw for the same deal as the toyota your going to make the change correct. Softball isn't any different.
If my daughter was from ohio and she accepted a spot on the sisters of the poor softball team, and 2 days later, the top lady lasers team called and asked her to play. I'm heading to the laser's sorry. (Just using them as an example, so any laser's posters don't take it personal)
A player has a very small window of opportunity to get exposure, and to play softball. These players are not owned by an organization, its a free country.
Let me guess Lebron was an idiot for leaving Cleveland where they weren't going to win an NBA title, to go to Miami where they where going to surround him with talented players to help him get better and in a place to succeed.
For those of you who get upset when someone asks your daughter to play even if they know she's committed. Be flattered and give them a polite no thank you. No harm in that, beats getting bent out of shape.
Also if the best player on your team left to go to a better team, it happens. Get over it.
