One thing the data reveals about NHL goalies is that most NHL goalies are consistently inconsistent overall. But not all are. Now I want to turn to looking at the NHL goalies that are consistently consistent. How do measure it? I propose the following: for an individual season, each NHL goalies performance using WAA is "graded" as follows: if they are in the top 20% of all NHL goalies for that season, they get an A, if they are in the next 20%, they get a B, and so on. Then an NHL goalie is consistent if they maintain their grade from one season to another. But I only am interested in the highest level of consistent performance, so I only count NHL goalies that from one season to another are among the top 20% of NHL goalies from the 1955/56 season to the 2019/20 season. Thus, they have to be consecutively in the top 20% of NHL goalies for each season to be counted on the list.
The most consistently excellent NHL goalie performance over their career was by Patrick Roy.
