my kid is a bantam age player so we have been around the block this year we have a parent on the team that I think is really crazy-beyond the typical hockey crazy.
has anyone had that before and what did you do

It depends on whay kind of "crazy." If the crazy parent it just embarassing himself/herself, leave it alone. If the crazy parent is hurting other parents, let them handle it. If the crazy parent is hurting you, your player (or any other player,) take it to the board of directors for your club.

If he is at cya95-redfaced angry, has a past that includes being wronged by the fury and it's coach, and at least one AA club and it's coach. Maybe! If not then....still maybe.
