I ran the numbers a few years ago: since the 2005 lockout: starter average for goalies is .915, so the goalie for each team who has the most icetime, averaged for every team per season, averages to .915.
For ALL goalies who have seen any icetime, average is .911.
Again, since the 2005 lockout. Bring the 80's into it and it drops. Big-time.
.912 is not bad, just run of the mill. If the D allows something like 25.1 shots against per game (which the 'hawks did), and a cup happens. Contrast to 2015: .924 with 30.5 shots against per game. Cup and Jennings.
This has implications for the current build. If we get a great goalie; like .920+, we can get away with looser D. If we get an average goaile, we will need smothering D.
If we get both? Like 2013? .929 and 26.2 shots against per game? Cup, Jennings, record winning streaks; the kind of year that makes you say, "Fuckin-A right Chicago!"
