I saw Chris Osgood described recently on an Internet message board as "the definition of a league average goalie", which I think is a pretty apt description. Grant Fuhr once again puts up pretty unimpressive stats. I'm surprised Mike Richter and Olaf Kolzig rank so low, but not surprised at all by Bill Ranford or Mike Vernon.
Current goalies who have done poorly so far by this metric include: DiPietro (-5%), Roloson (-6%), Gerber (-16%), Fernandez (-18%), and especially Miller (-39%!).
Finally, let's look at which goalies have the most expected shutouts. That is, if you substituted a league average goalie in to play the same minutes, how many shutouts could we expect them to have? This table shows why the all-time shutout record is so hard to break - it requires durability, good teammates, and playing in a defensive era. Only two goalies in the post-WHA era had even an outside shot at breaking Sawchuk's record, and this list shows how the guy who eventually is going to do it had quite a bit of an advantage over the rest of his peers:
