◆ By the ModelJul 11, 11:19 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

Expected goals predicted a toss-up—4.31–4.23 favoring Calgary—yet Seattle won 5-1. That four-goal scoreline wasn't written in the underlying play; it was goaltending and shot quality that created the gulf.

P. Grubauer stopped 3.31 goals above expected, turning an even xG split into a rout. He posted 0.976 SV% on 42 shots, perfect on high-danger chances (5-for-5). D. Wolf absorbed the variance: 0.852 SV%, victim of superior shot quality.

Calgary owned volume—60% of shot attempts (42–28)—but volume meant little. Their xG per shot (0.056) lagged Seattle's (0.086). In high-danger situations, the pattern crystallized: Calgary was 0 for 5; Seattle generated 10. On the rush, Seattle was clinical (2 goals on 22 chances). Rebound opportunities told a parallel story: Calgary found 4 (1 converted); Seattle found 6 (2 converted).

Matty Beniers's wrist shot from the slot (P3, 17:39) marked the turning point—confirming that Seattle's efficiency would overwhelm Calgary's volume.

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 11, 11:16 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 draws a 53% Flames win probability—Seattle and Calgary are separated by a single goal, at best. Expect a game where bounces and discipline matter more than talent.

Calgary owns territorial command. Their 49.0% Corsi suggests they'll dictate where play happens; Seattle's 45.0% means they'll spend the night chasing. But expected goals tell a narrower story: Calgary at 47.0% xG%, Seattle at 46.0%. The teams generate nearly identical shot quality.

Calgary's 0.985 PDO is the red flag. Running cold on conversion and luck, they're due for variance to swing their way. Seattle's 1.011 PDO runs hot—usually a sign of regression incoming. If puck luck aligns with territory, Calgary's advantage widens. If variance regresses Seattle's way, the coin flip tilts Seattle.

D. Wolf starts on a back-to-back. Watch whether Calgary delegates to a backup or asks him to gut out tired legs. In a 1-goal game, that decision could echo.

Shane Wright drives Seattle's attack at 0.77 xG/60, with 8 goals on 10 assists and 4 hard-chance markers. His 10.4% shooting rate is high but survivable. Berkly Catton sits leaner at 0.68 xG/60 with 6 goals, 8 assists, and 8.8% shooting—but his 5 hard-chance goals make him a higher-variance threat.

Blake Coleman anchors Calgary. His 0.89 xG/60 and 16-goal season rank elite. But 11.4% shooting suggests unsustainable conversion; regression stalks him. Matt Coronato's secondary thrust—0.80 xG/60, 10 goals, 16 assists—features a 6.6% shooting rate hinting at healthier efficiency floor.

Both rosters record 0% hard-chance and 0% rebound-goal rates, an artifact likely driven by counting rules rather than true dominance. Seattle's Chandler Stephenson represents their defensive seam. Calgary's weak link, surprisingly, is Coronato—though his offensive ceiling complicates simple defensive labels.

The 53% line is honest. This goes either direction.
