Mammoth run the Maple Leafs off the ice on the underlying numbers

The verdict · earned

The Mammoth earned it — the game and the expected-goals battle both.

TOR 1 · UTA 6
◆ By the ModelJul 12, 12:39 AMxG: xgboost-0.758Edited 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

Utah's dominance extended across every underlying metric. They controlled 70% of expected goals (5.66–2.41), 67% of shot attempts (41–20 on goal), and a 12–4 high-danger chance advantage—a combination that rendered the 6-1 result inevitable.

The Mammoth's efficiency was relentless. They generated 0.062 expected goals per shot versus Toronto's 0.046, a quality gap that predicts their dominance. K. Vejmelka posted 19 saves on 20 shots (0.950 SV%), stopping 1.41 goals above expected. D. Hildeby made 35 saves on 41 shots (0.854 SV%), facing far greater volume and higher-danger chances. The Maple Leafs underperformed their expected goals by 1.41, a variance that widened the gap between the underlying 70-30 split and a 6-1 scoreline.

Utah converted efficiently. They scored 5 goals on 37 rush chances, a conversion rate that transforms speed into sustained scoring. They scored twice from low-danger spots—the kind of opportunism that separates routs from close contests. Crashing the net effectively, they generated 8 rebound opportunities and converted one. Toronto managed 3 rebound chances with one conversion, a metric underscoring their secondary-play limitations.

The game's trajectory was set early. Daniil But's snap shot from the slot at 16:54 of the third period exemplified Utah's sustained control, though the contest had been decided long before by superior shot generation and goaltending.

New to these numbers?

Two things happened in this game: who created the better chances, and who put the puck in the net. They are not the same thing, and this page separates them on purpose.

The one to watch is expected goals— the best single read on who deserved to win. When it disagrees with the scoreboard, that disagreement is usually the story. Nothing here is a projection; every figure is computed from this game's play-by-play. Full glossary →

xG
Expected goals. Every shot scored by how often that exact look goes in. 2.5 xG means the chances were worth about two and a half goals.
HD
High-danger chances — shots from the slot and the crease, where shots actually become goals.
Corsi
Every shot attempt, including the ones that missed or got blocked. A rough read on who had the puck.
Adj.
Score-adjusted. Teams that trail shoot more and teams that lead sit back, so this corrects the attempt count for the scoreboard.
GSAx
Goals saved above expected. A positive number means the goalie stopped more than an average goalie would have on those shots.
PDO
Shooting % plus save % — a luck gauge. It sits near 1.000 over a season, so a game far from it usually means the bounces decided it.

The read

Edited for clarity
◆ By the ModelJul 12, 12:38 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

Utah owns the territorial and shot-quality edge. The model projects a 2.3–2.8 game with the Mammoth at 58% win probability, granting Utah control of both possession and scoring opportunity.

Toronto has heated up—seven wins in their last ten—but underlying play tells a different story. Utah's 52.0% expected goals against 46.0% means the Mammoth generate higher-quality chances. Corsi strengthens the case: 53.0% to 45.0%, indicating Utah will dominate puck possession and force Toronto into reactive defense.

The goaltending matchup carries risk. V. Vanecek plays the second night of a back-to-back, vulnerable to fatigue or benching.

Auston Matthews anchors Toronto's attack at 1.10 expected goals per 60 minutes, with 17 goals and 13 assists on a 10.6% shooting rate—efficiency still intact. John Tavares has posted 15 goals and 24 assists at 0.91 xG per 60, though his 12.4% shooting eclipses his underlying output. Toronto's secondary scoring is running hot, not sustainable.

Dylan Guenther leads Utah at 28 goals and 15 assists with 1.02 expected goals per 60 and a ruthless 16.8% shooting rate. Daniil But carries 1.01 xG per 60 despite just 2 goals and 2 assists—a volume play due for regression to the mean.

Utah's offensive edge exploits Toronto's defensive weak link: Bo Groulx. Toronto faces its own stumble at Maveric Lamoureux, though recent form suggests they can overcome such vulnerabilities.

Form shifts; underlying play persists.
