Equal chances, unequal results. The teams sent the same number of shots on goal—33 each—yet the Mammoth won 4-3 in overtime. The difference came down entirely to execution. The underlying numbers backed it up: Utah generated far more dangerous opportunities, creating 0.064 expected goals per shot versus Colorado's 0.040.

Utah was clinical where it mattered most. They scored 2 of 5 high-danger chances (40%) and 2 goals off the rush on 28 attempts. Colorado scored twice from low-danger locations—the kind of play that goaltenders should not allow—and added one more off the rush on 22 attempts. Both teams crashed the net with five rebound opportunities each, but only Utah converted: 2 from 5. Colorado got nothing.

Utah's expected-goals advantage was substantial (3.38 to 2.59, a 57-43 split). Goaltending reinforced the gap: S. Wedgewood stopped 29 of 33 for Colorado (0.879 SV%, 0.62 worse than expected), while K. Vejmelka saved 30 of 33 for Utah (0.909 SV%).

Dylan Guenther ended it 33 seconds into overtime with a backhander from the slot.

Colorado's expected win probability sits at 52% in a matchup the model projects at 2.7 - 2.6. That's about as close to a pick'em as you'll find. The Avalanche own the underlying play by a thin margin, but Utah has enough to stay competitive.

The Avalanche drive the puck with real authority at 5v5. Their 57.0% expected goals share dwarfs Utah's 52.0%—that's meaningful separation in shot quality. Territorial advantage shows up in Corsi too, where Colorado's 57.0% to Utah's 53.0% suggests they'll spend most of the night in Utah's end. But Utah's 53.0% Corsi isn't weak for a team facing a top-tier opponent; it means they won't get pushed around wholesale.

Colorado has to manage their luck. Their 1.021 PDO signals they're running hot relative to their underlying quality, while Utah sits at 1.003—nearly neutral. That gap matters. If Avalanche regression hits mid-game, Utah could seize momentum.

The player matchups cut both ways. Artturi Lehkonen remains Colorado's engine at 1.11 xG/60 with 18 goals and 22 assists; he's generating high-danger chances at a 6-goal clip and converting at 14.9%, well above his workload. Ross Colton carries 1.10 xG/60 with 7 goals and 15 assists but is shooting just 4.9%—if he normalizes, Colorado gets even scarier.

Utah counters with Dylan Guenther, who leads with 28 goals and ranks at 1.02 xG/60. His 16.8% shot rate is elite, but it's also a ceiling that typically doesn't hold; Colorado's defense will make him earn it. Daniil But supports at 1.01 xG/60 with 2 goals and 2 assists—secondary volume that limits his leverage in a tight game.

Colorado's defensive weak link, Nazem Kadri, could see Utah probe for matchup advantages on the power play or in transition. Utah will lean on that. Maveric Lamoureux occupies a similar role for Utah, creating an asymmetry that matters if Colorado's depth forwards execute.

The razor-thin margin in Colorado's favor—52% win probability, a 4-percentage-point edge in xG%, a 4-point Corsi advantage—hinges on shot quality and execution. Lehkonen's elite conversion rate gives Colorado the edge. But Guenther is prolific enough to steal this if the Avalanche's luck regresses. This is a game where the better team might not win.
