Measuring save quality
Comparing netminders' performance is always tricky business, mainly due to the fact that every goaltender has a different cast in front of him and, as a result, faces an entirely different level of shot quality. Martin Brodeur, for example, may make many of his saves on shots from a long distance due to the strength of his defenders, while someone like Ilya Bryzgalov faces far more shots from closer range.
Gabe Desjardins has been working on a netminders study that evaluates the quality of shots they face, and then attempts to rank them when compared to an average goaltender facing those same scoring opportunities.
There's a lot of data there, but it's interesting to see that goaltenders like Pascal Leclaire and Dom Hasek are facing fewer difficult shots, while Jason LaBarbera and Henrik Lundqvist have a much tougher task every night.
