What a stupid rule, not allowing the goal. Why do you have refs anyway if you just could make the decisions afterwards. I think that the only help they should get is to see if the puck is in or not. Very vague(?) rules if the goal from Czech Republic vs. Sweden counts when the czech inteference Kronwall in to his own net but not this. Can't see the difference. I think that if the video reviewer can decide one of this things he can decide the other too. But anyway my opinion is that the reviewer only should decide if the puck is over the line or not. Otherwise we can play without refs on the ice. In floorball, a popular game here in Sweden similiar to hockey, it's a goal if the ball crosses the line even if the cage is knocked over or away from it's position. I think it should be the same in hockey.
Sorry for HORRIBLE english. Just wanted to say my opinion.
