◆ By the ModelJul 12, 8:04 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's 4–1 win had a sharp disagreement with its underlying metrics: the Avalanche went 0–9 on high-danger chances while Soderblom stopped all nine. They won instead on rush volume, scoring 4 goals on 34 rush opportunities—a ratio that overwhelmed Chicago's transition defense.

The Blackhawks held 29% of shot attempts and generated 2.72 expected goals, then squandered even that meager share. Blackwood saved 1.72 goals above expected, suffocating Chicago whenever they approached the net with purpose. Colorado paid for their own inefficiency in the slot: they underperformed their 5.25 xG by 1.25 goals, a consequence of Soderblom's near-perfection on high-danger chances. Yet Colorado's relentless rush attacks, combined with 8 rebound opportunities against a scrambling defense, proved unstoppable.

Chicago never escaped the defensive zone long enough to generate sustained offense. Colorado's volume in transition was the deciding factor.

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, 8:03 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 Colorado at 3.0–2.4, marking the Avalanche as 61% likely to win. The underlying numbers support that, but one caveat looms: Colorado's PDO has inflated its results.

At 57.0% expected goals and 57.0% Corsi, Colorado dominates the territorial battle. Chicago manages just 42.0% xG% and 46.0% Corsi, a gap mirrored in its minus-5 goal differential over the last 10 games.

Expected goals measure shot location. Corsi counts all attempts regardless of danger. Both favor Colorado. But shooting and save percentage—the luck components in PDO—have run to Colorado's favor at 1.021. Chicago sits at 0.996. These rates almost always regress.

S. Knight and S. Wedgewood both face back-to-backs, raising the question of a backup or tired starter.

Artturi Lehkonen (18G, 22A) leads Colorado with 1.11 expected goals per 60 and 6 high-danger chances. Ross Colton (7G, 15A, 1.10 xG/60) carries a 4.9% shooting rate. Chicago counters with Tyler Bertuzzi (20G, 15A, 0.85 xG/60, 7 HD goals, 18.0% shooting) and Connor Bedard (17G, 27A, 0.82 xG/60, 5 HD goals, 11.8% shooting).

Nazem Kadri is Colorado's defensive weak link; Anton Frondell plays the same role for Chicago. Neither team generates meaningful rebound or high-danger goals—both sit at 0%—which tilts play toward sustained possession and shot volume.
