What do you make of this? I don't think thats difficult at all. That kid probably put a shitload of wax on his stick and practiced it again and again, making it easy. And I understand he's nine, but still, I coach childrens hockey and I play myself and I know a ton of good nine-year-olds could pull off that move with practice + wax. And plus that puck is blue making me think it might be a lighter puck.
And on the other hand, the nine-year-old (I'm assuming) goalie, probably has never seen that before, but any goalie that has seen that trick before could easily stop it.
