Mammoth pull away from the Stars

The verdict · stolen

The Mammoth stole one. They lost the expected-goals battle 2.80–3.54 and won anyway.

UTA 6 · DAL 3
◆ By the ModelJul 12, 7:31 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 defeated Dallas 6–3, but the scoreline masks what happened on the ice. Dallas dominated process, controlling 56% of expected goals. The Mammoth stole this one.

The Stars' supremacy started in the shot battle. Dallas held 58% of shot attempts, 30 on goal to Utah's 22, translating to a 3.54–2.80 xG advantage. By the math of hockey, Dallas was the better team. Utah just finished better.

The gap between process and result came down to two factors: goaltending and efficiency on the rush. V. Vanecek saved 27 of 30 for Utah, running 0.54 goals above expectation. C. DeSmith faced 21 shots and surrendered 2.20 more than expected—an indictment of his performance regardless of Dallas's shot volume. Utah also dominated the high-danger zone: two goals on five chances (40%) against Dallas's eight high-danger attempts. Utah added three low-danger goals, shots DeSmith should have had.

On the rush, Utah's superiority was decisive. The Mammoth scored five on 22 rush chances; Dallas scored three on 25. That efficiency, plus the softies, pushed Utah to 3.2 goals over their expected output.

Adam Erne's snap shot from the high slot in the third period became the turning point—a real, dangerous moment when Utah's execution began to overwhelm Dallas's control.

Dallas created the better game and got nothing. That's the story here.

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, 7:30 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 projects a UTA 2.5 - 2.5 DAL game with the Stars at 50% win probability—as close to a pick'em as you'll find in the NHL.

Dallas arrives hotter by points pace, posting a 9-0-1 mark over their last 10 games. Utah has trended in the opposite direction with a minus-6 goal differential over the same stretch. The underlying analytics reveal two evenly-matched teams. Utah drives play at 53.0% Corsi%, while Dallas lags at 47.0%. Expected goals tilt slightly to Utah at 52.0% xG% against Dallas' 51.0%. But the Stars are running hot at 1.024 PDO—a number due for regression.

Both teams face goaltending uncertainty on back-to-backs: J. Oettinger and K. Vejmelka may see backups or tired starters.

Players to Watch

UTA

  • Dylan Guenther — 1.02 xG/60, 28G 15A, 3 HD goals, 16.8% shooting
  • Daniil But — 1.01 xG/60, 2G 2A, 1 HD goals, 5.6% shooting

DAL

  • Jason Robertson — 0.96 xG/60, 25G 21A, 2 HD goals, 12.4% shooting
  • Michael Bunting — 0.83 xG/60, 8G 14A, 7.6% shooting

Utah's territorial edge is real—they'll control puck movement—but Dallas' hot PDO and fresher momentum create openings for the home team. The defensive weak links matter here: Maveric Lamoureux for Utah, Tyler Myers for Dallas. Whoever capitalizes on these mismatches in a match this even wins a game that's genuinely a coin flip.
