Has there ever been any effort to normalize shutouts? I look at the all-time shutout leaders and it's riddled with goalies who played before the forward pass. John Ross Roach, Lorne Chabot, George Hainsworth, etc. Clearly this is disproportionate to their relative skill level as goalies. And it's the opposite for the 80s. Guys like Fuhr, Smith, Barrasso, etc should probably have more shutouts than they currently do. As someone unfamiliar with data manipulation, I need to ask - what's the best way to go about normalizing shutouts? Is it even possible?
