Methodology
Chance quality belongs to the environment. The result above expectation belongs to the goalie.
Defense: xGA/60 estimates the scoring danger of all unblocked attempts—including misses—while the goalie was on the ice. Lower is better. SA/60 and high-danger SA/60 are available as alternate views.
Goaltending: GSAx is on-target expected goals against minus actual goals against. Positive means the goalie stopped more than the model expected. Missed shots are not credited as saves. Rates use shift-derived 5-on-5 ice time.
Separate defensive and goaltending expected-goals models are trained exclusively on 2025–26 regular-season 5-on-5 outcomes. Both use shot distance, angle, type, and whether a saved shot by the same team occurred within the previous three seconds. “High danger” means an on-target shot had at least — expected goals.
Important limitation: official play-by-play does not consistently record screens, pre-shot passes, or rush context. The chart measures the recorded shot environment, not every defensive contribution.
