I feel like every year or even few months this thread pops up and we have to explain why it's wrong.
Widening the rink only makes it easier for "skill" players if your defensemen are stupid. If a defenseman has a really fast forward bearing down on him, the answer is not to chase the forward wide. The answer is to skate straight backwards and keep your body between the puck and the net. I think people imagine a fantasy where the forward goes wide into the extra wide ice, the defenseman chases him wide and gets beat with speed and the forward gets a penalty shot on the goalie. In actuality, the defenseman will sit straight back and prepare for a shot block, the forward will probably peel back and wait for his team to catch up.
So every year we have to pull up the statistics to show that in the SHL and the Liiga and all the top European leagues, scoring is actually LESS than in the NHL. For those exact reasons.
