◆ By the ModelJul 11, 5:25 PMxG: 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 1-0 victory understated their dominance. They controlled 63% of 5v5 expected goals (3.03 to 1.77), marking a decisive advantage in shot quality that the scoreline didn't fully reflect.

The Avalanche dominated the chances. They generated four high-danger opportunities to Chicago's one, and registered 0.054 xG per shot compared to Chicago's 0.033—a gap that matters when games are decided by margins this thin. Colorado's offensive execution faltered, though, underperforming their xG by 2.03 goals.

Chicago relied on volume rather than quality, holding 46% of shot attempts (22 to Colorado's 26) but creating only 1.77 xG. They crashed the net effectively, generating three rebound chances, but converted none. The underperformance was steeper: Chicago left 1.77 goals on the table.

Cale Makar ended the stalemate with a wrist shot from the high slot at 18:21 of the second period. That single goal proved decisive despite Colorado's relative profligacy.

The goaltending told a different story: both starters were exceptional. S. Wedgewood stopped all 22 shots for a perfect 1.000 SV%, performing 1.77 goals above expected. S. Knight faced the far more difficult task, allowing one on 26 shots (0.962 SV%), yet still exceeded expectations by 2.03 goals. In a low-scoring game where chances scattered unevenly, both goalies kept the margin narrow.

Colorado's control of shot quality—high-danger chances and xG per attempt—should have produced a wider margin. Instead, they escaped with a one-goal win against a team that had no answer for their sustained pressure.

      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 11, 5:31 PMEdited 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 Colorado win at 3.0–2.4 with the Avalanche at 61% win probability. That edge is backed by real hockey, not happenstance.

      Colorado is the hotter team—9–0–1 in their last 10 games—but more telling is their dominance in expected output. At 5v5, they command 57.0% expected goals and 57.0% Corsi%, pinning Chicago (42.0% xG, 46.0% Corsi%) to the perimeter. The game will be geographically lopsided: Colorado in Chicago's zone, Chicago chasing.

      The hidden risk: Colorado's PDO of 1.021 means they're converting at a pace well ahead of their underlying quality. Chicago's 0.996 PDO sits near equilibrium. That spread will regress—not enough to flip the game, but enough to tighten the margin. The Avalanche remain the lean, but expect a closer affair than their recent scoreline suggests.

      A. Soderblom starts on a back-to-back for Chicago. Fatigue could open the door for Colorado's volume to cash in faster.

      Players to Watch

      Colorado

      • Artturi Lehkonen — 1.11 xG/60, 18G 22A, 6 high-danger goals, 14.9% shooting
      • Ross Colton — 1.10 xG/60, 7G 15A, 1 high-danger goal, 4.9% shooting

      Chicago

      • Tyler Bertuzzi — 0.85 xG/60, 20G 15A, 7 high-danger goals, 18.0% shooting
      • Connor Bedard — 0.82 xG/60, 17G 27A, 5 high-danger goals, 11.8% shooting

      Nazem Kadri is Colorado's defensive liability. Anton Frondell is Chicago's. Both leak chances, but Colorado's territorial advantage should limit how many prime looks Chicago actually gets.

      The math and momentum both point Colorado. The edge is real. It's just smaller than the PDO gap suggests.
