I'm not condoning the coaches actions by any means, but pouting on the bench probably isn't the best way to get more ice time. 9 is young no doubt, but grade 4 me didn't cry when I was stapled to the bench playing recreational basketball. I practiced more then eventually realized I just suck at basketball and moved onto something else.
And yes, I'm fully prepared to get flamed by all the over protective parents who envision this happening to their child.
