Avalanche pull away from the Penguins

The verdict · stolen

The Avalanche stole one. They lost the expected-goals battle 2.49–4.16 and won anyway.

◆ By the ModelJul 12, 8:43 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

Colorado stole this one. The Penguins controlled 63% of expected goals at 5v5, held 52% of shot attempts, and won the high-danger chances 7-4. They still lost 6-2.

This is what happens when goaltending variance breaks badly. S. Wedgewood was 2.16 goals above expected; A. Silovs was 2.51 goals below. The Penguins had the chances. The Avalanche had the execution.

Colorado generated 3.51 goals above their xG — elite finishing or bounces breaking right. Pittsburgh underperformed their xG by 2.16, wasting high-danger looks that should have buried the Avalanche. The Penguins created openings. The Avalanche converted them.

One shift tipped the balance: Ross Colton's wrist shot from the wing at 16:20 of the third period, on a night when Colorado was lethal in transition. The Avalanche scored 3 goals on 15 rush chances — a conversion rate that rendered Pittsburgh's territorial advantage pointless.

Colorado also dominated the net-front, generating 3 rebound opportunities and converting 1. Two Avalanche goals came from low-danger areas, the kind a goalie should stop. S. Wedgewood faced 32 shots and stopped 30; A. Silovs faced 29 and stopped 24. A 0.938 save percentage beats a 0.828 save percentage.

For Pittsburgh, the math is cruel: a 63-37 expected-goals advantage means nothing when the other team finishes and your goalie doesn't. The Penguins had possession and chances. They lacked execution.

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, 8:41 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 2.8–2.6 Avalanche win with Colorado at 53% win probability. This is about as close to a pick'em as you'll find.

Colorado owns the underlying play. The Avalanche shoot 57.0% xG% and control 57.0% of Corsi at 5v5—that territorial advantage should feel comfortable in a low-score game. Pittsburgh generates just 51.0% xG% and 50.0% Corsi%, a significant disadvantage when the puck spends two-thirds of the game in your defensive zone.

The Penguins come in wounded. They're -7 on goal differential over their last 10 games, the kind of sink that doesn't recover in a single night. For Pittsburgh to steal this, they need to tighten defensively and avoid giving Colorado the possession advantage they've built.

Here's the wrinkle: Colorado's PDO sits at 1.021—they're running hot—which means some regression is baked into any projection favoring them. Pittsburgh's 1.012 is closer to sustainable, a minor edge in a coin flip that cuts both ways.

Artturi Lehkonen drives Colorado's offense. He's at 1.11 xG/60 with 18 goals and 22 assists; six of those goals have come from high-danger chances, and he's shooting 14.9%. He's the player Pittsburgh must neutralize. Ross Colton supports him at 1.10 xG/60, but his shooting line tells you where Pittsburgh's defense has the best chance to limit damage—Colton has just 7 goals on 15 assists with a 4.9% shooting rate, well below league average.

Pittsburgh's offense hinges on Rickard Rakell, who carries 1.01 xG/60 and has converted 13 goals and 13 assists. Three of his tallies are high-danger; he's shooting 12.1%, a rate that suggests he's overperforming his chances. Filip Hallander, who leads the team at 1.28 xG/60, is likely out on IR and unavailable, removing Pittsburgh's most dangerous creator from the matchup.

Nazem Kadri is Colorado's defensive liability; Caleb Jones is Pittsburgh's. Both teams sit at 0% high-danger and rebound goal rates—an anomaly neither can sustain. This is a possession game with Colorado favored by underlying numbers but punished by heat-adjusted regression. Pittsburgh's only path runs through tighter defensive structure and Rakell's conversion. The 53% call is right: either team can win, and the model knows it.
