The Islanders stole one. They lost the expected-goals battle 2.01–2.35 and won anyway.

NYI 4 · PHI 0
◆ By the ModelJul 12, 3:07 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

The Islanders won 4-0 despite a disadvantage in shot quality. The Flyers generated 2.35 expected goals to the Islanders' 2.01. Yet goaltending and execution diverged sharply: I. Sorokin posted a 1.000 save percentage while the Flyers' S. Ersson finished at 0.826.

Sorokin turned away all 21 shots despite facing 2.35 xG, a +2.35 save above expectation. Ersson surrendered four goals on 23 shots, allowing 1.99 more than his xG of 2.01 suggested. The gap between expected and actual was wide enough to cover the entire margin.

The Flyers held 48 percent of shot attempts and created three high-danger chances to New York's two. On the board, they outworked their opponent. In execution, they wasted every chance—underperforming their xG by 2.35 goals. The Islanders, conversely, overperformed theirs by 1.99 through rush opportunities and net-crashing that turned loose pucks into goals. On a neutral night, this game lived close to 2.01 vs 2.35. On this one, goaltending and conversion separated them completely.

M. Barzal recorded a goal and an assist in 17:29, while A. Duclair added two assists in 16:02. Jean-Gabriel Pageau scored twice, including a wrist shot from the high slot in the third period.

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, 2:41 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 Flyers get a coin flip at home. Models project a 2.3-2.6 New York goal margin in Philadelphia's favor—close enough that 55% win probability barely qualifies as an edge.

The underlying advantage belongs entirely to the Flyers. Philadelphia owns 51.0% expected goals at even strength versus the Islanders' 48.0%, yet New York has squeezed slightly better possession value: their 49.0% Corsi sits fractionally above the Flyers' 48.0%, meaning they're not out-chanced so much as outgunned. Philadelphia's luck has run ahead—a 1.008 PDO suggests their conversions will normalize. The Islanders' 0.993 PDO points the other way, implying positive regression in their near future.

Anders Lee anchors the Islanders' attack at 1.20 expected goals per 60 minutes. His 9 goals and 20 assists include 2 from hard chances, but his 6.4% shooting rate trails what volume forecasts. Bo Horvat drives at 0.87 xG/60 with 18 goals, 10 assists (3 from hard chances), banking 12.8% shooting. Owen Tippett leads the Flyers at 0.88 xG/60—19 goals and 18 assists with 2 hard-chance conversions at 12.1%. Christian Dvorak complements at 0.81 xG/60, scoring 12 goals and 21 assists (3 from hard chances) on 11.2%.

Neither team scores from hard chances or rebounds (both at 0%), concentrating all scoring into primary chances. Alexander Romanov is the Islanders' defensive weak link. Christian Dvorak fills that role for Philadelphia.

This is a true coin flip. The Flyers own the underlying play, but regression tilts toward the Islanders. Neither margin tips much beyond the home-ice edge.
