Hi there,

I've compiled the data about goalies regular season Z-Score (# of standard deviations above the mean), because I couldn't find it on the internet or here on forums (it seems that some data was lost in migration). Z-Score is IMHO the best tool for measuring goalie dominance over his peers.

Data:
nhl.com

Method:
Calculate season weighted (goalies facing more games are more significant to the result) mean sv%, measured goalie excluded:

X' = Sum1..N(Wi * Xi)/Sum1..N(Wi)

Xi - Save percentage
Wi - Shots against
N - number of goalies playing at least one game, measured goalie excluded

Calculate season weighted standard deviation. Again measured goalie excluded:

SD = sqrt(Sum1..N(Wi * (Xi - X')^2) / (((N-1)/N) * Sum1..N(Wi)))

X' - Weighted mean
Xi - Save percentage
Wi - Shots against
N - number of goalies playing at least one game, measured goalie excluded

Calculate goalie Z-Score

Z-Score = (X - X') / SD

X - goalie Sv%
X' - weighted mean Sv%
SD - weighted standard deviation

  • Dominik Hasek is (as expected) by this metric the most dominant regular season goalie ever, with 7 straight seasons in Top 100.
  • Although Hasek's two best seasons are significantly better than Roy's, Roy's top 7 seasons stack surprisingly well against Hasek 3rd to 6th best seasons.
  • Martin Brodeur only appears on this list once which confirms that his peak was far behind both Hasek and Roy.
  • Tim Thomas's peak seasons rank very high on the list (12th, 13th), which are two most dominant seasons post lockout.
  • Marc-Andre Fleury 2017-2018 performance grants him 91th place on this list.
  • Very few season from 50', 60' and 10' appears on the list. The reason for this is probably that decades are incomplete (50', 10') and because of O6 era (50', 60').
