When I played atom AA, the coach was Paul Menard. I'm 33 now but I will never forget that experience. It was so bad, when he coached Midget espoir later on, I refused to play for him and went straight to Midget AA. He did everything in his power to prevent me from playing AA until my father threatenned legal action.
He would constantly bench kids, 12 year old boys, in favor of his son, sometimes the kids would play 1 shift the entire game. I remember kids crying in the room and on the bench, he never once went to talk to them. He would yell at the top of his lungs if you made a mistake in a drill during practice. On top of that, he was extremely rude with most parents, including mine. We're talking about Atom here man, the idea is to get kids to love the game. A few years later, a bunch of guys on my team, including his own son, had moved on to other things.
All in all, I can confirm that Paul Menard is a sack of sh*t and I'm not surprised people are quitting.
