Classy way:
- Thank the coach(es) for their time and effort with your DD.
- Keep the "why" as simple as you can - "We feel it's time for us to move on".
- Wish them well for the future.
Not-classy way:
- Talk crap about the coaches to other parents during what you know will be your DD's final game.
- Pull your DD off the team in the middle of a tournament.
- Write a long letter/email to the HC blasting every member of the coaching staff, and insulting players.
Be classy.
If what the OP says is true, I doubt that these parents are the only ones saying WTF is going on with this org? It is human nature to talk to each other to ensure your perspective is in line rather than out of whack. Doesn't sound like it's the coaching but the org that's the problem. Chances are other parents are attuned to this as well and there is much discussion going on behind the scenes. Been there before and whether it's classy or not, when something stinks people talk.
