What you've described about the mistakes can happen to any team on any day, but it's quite common when a hyper-competitive coach tries to take a rec team into TB.
HC needs to take his daughter and go form a team with players that he actually wants. If your DD is one of those players, you've got some soul-searching to do. By that I mean, were there signs of this behavior a year ago? Or is it all new this spring? And if it's been there all along, can you tolerate it and do you want your daughter around it?
Not an environment I want my daughter in. Many parents and spectators are ready to say something.
