NHL Goaltending Composite Efficacy — Methodology
This dataset is a quantitative evaluation of NHL goaltending performance across the 2021–2026 era — regular season and playoffs, single seasons and multi-year aggregates.
Eleven reports cover the era: six regular season (five individual seasons plus a five-year aggregate) and five playoff (four individual postseasons plus a four-year aggregate).
The Composite Efficacy Score
Standard goaltending metrics (Win % or Save %) fail to account for the disparity in team defense and offensive support. To correct for this, we established a Composite Score — the arithmetic mean of a player’s rank across five distinct performance pillars:
- Win Rate (W/GP): Measuring the frequency of favorable outcomes.
- Shutout Rate (SO/GS): Measuring the frequency of absolute performance peaks.
- Save Efficiency Ratio (Svs/GA): A raw ratio of successful interventions to failures, providing a more granular view than Save Percentage.
- Loss Suppression (L/GS): The inverse ranking of loss frequency per start.
- Victory Efficiency (GA/W): Measuring the defensive “cost” of a win (goals allowed in games won).
A lower Composite Score is better. A goaltender who ranks #1 across all five pillars scores a 1.0.
Inclusion Criteria
Minimum games played thresholds vary by report type to filter out small-sample anomalies while preserving meaningful data:
| Report type | Minimum GP |
|---|---|
| Regular season (single) | 15 |
| Regular season (5-year aggregate) | 50 |
| Playoffs (single) | 5 |
| Playoffs (4-year aggregate) | 10 |
Why These Pillars
Win Rate and Loss Suppression together capture outcome efficiency without double-counting. A goaltender can suppress losses (play well in losses) without winning — this separates team-driven wins from individual performance.
Shutout Rate identifies peak performance. A shutout requires elite shot-stopping and is independent of offensive output — it is the clearest single-game signal of individual goaltender dominance.
Save Efficiency Ratio is a raw interventions-to-failures ratio. Unlike Save Percentage, it does not normalize — a goaltender who faces 40 shots and allows 1 is measured differently from one who faces 25 and allows 1, even though both post a .960 save percentage in that game.
Victory Efficiency measures the defensive cost of winning — goals allowed per win. It penalizes goaltenders who win only in blowouts and rewards those who steal close games.
Reading the Reports
Each report presents a top-20 ranking table followed by detailed analysis of the findings. The Composite Score is the primary ranking criterion. Individual pillar ranks are used in the analysis to explain the drivers behind each goaltender’s position.
