There's no point in getting angry at the players or team or whining about the refs - this is just what the NHL has become. The league is so low scoring that you can badly outplay the other team and lose. Half the games now are decided by luck. If the Leafs consistently dominate their opponents like this they will win most of the games.
If you want to blame somebody, campaign to have the size of the nets increased slightly, so that when we get a billion chances the odds of getting some goals out of it are higher.
