The Mammoth are the model's lean over the Kraken — with PDO regression in play

The read

Edited for clarity
◆ By the ModelOct 22, 9:13 AMEdited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The model favors the Mammoth, and the reason has more to do with how the game has gone than with who has finished the chances. The projected score is 3.4-3.0, which is close, so the edge has to come from somewhere other than the scoreboard.

The Mammoth own the underlying play. They hold 59.1% of five-on-five expected goals, which measures the quality-weighted chances a team creates. Shot attempts point the same way, so expect the game to tilt toward Utah's end of the ice.

Seattle's best argument is luck. The Kraken's PDO, the sum of on-ice shooting and save percentage, sits at 1.050. That is running hot, and some regression should be expected.

The season numbers at five-on-five, side by side:

MetricMammothKraken
Expected goals share59.1%46.8%
Shot attempts share56.8%43.8%
PDO0.9941.050

In goal, S. Cossa is the concern. He sits at -3.1 goals saved above what his shots should have allowed over 4 games. His save percentage is 82.0% across those same games.

P. Grubauer is the counterweight. He sits at +1.2 goals saved above what his shots should have allowed over 6 games. His save percentage is 90.4%.

The lean is real but not comfortable. Utah's territorial edge is the stronger case, and Seattle's hot shooting and save numbers are the reason it is not a runaway.

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.
