I vehemently agree that the game needs to be called by the book. But I think it's even more important than you implied. It is FAR more important than the size of goalie equipment, which to me is one of the more overrated reasons why scoring is depressed. It is hard to tell, since the increase in size has coincided with the decrease in penalty calls, so it's hard to say which contributes more. But I think calling the rules as they are would do far more to increase scoring than reducing equipment size.
