It looks like neither side is without blame. If a program requires a one year commitment, that should mean something. Especially when you are the only goalie on the team. It would have been more honorable for the family to play out the one year commitment and then switch teams. They could have invested in a private position coach for temporarily while fulfilling her team commitment.

But the email was way over the top, both nasty on a personal level and bad business.

A club lacrosse program needs to be smart and take the high road when a customer does something wrong. They should have politely reminded her of the one year commitment, but if she insisted on leaving, wished her well and began the search for a new goalie. An email like that never ends well for the program that sends it.

I hope this helps.
