New to these numbers?

This is a preview, so every number on it is about form and rates — what each club has been doing, not what it will do tonight.

The strip above is the model's lean, built from each side's chance creation and prevention, goaltending, rest and home ice. It is not a betting line and nobody here is telling you to wager on it. Full glossary →

Win prob
How often this matchup ends in a win for that club, over many simulated tries. It is a lean, not a prediction — 60% teams lose plenty.
xGF/60
Expected goals a club creates per sixty minutes of play — its scoring-chance rate, independent of how many games it has played.
xGA/60
The same rate for chances it gives up. Lower is better.
PDO
Shooting % plus save % — a luck gauge that drifts back toward 1.000. Well above it flags a club that has been running hot.
