Even if it is on purpose, though, it is usually just one slash. These types of slashes typically come from the goalie to warn a player that he is too close to his crease.
Well, in this junior game, there was a slash that was on purpose, but it was also way more than one slash.
I am hoping that this kid doesn't play hockey for a while, and instead, his parents assist him in reaching out for help with his anger.
