◆ By the ModelJul 12, 8:40 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 dominated this game—66 percent of shot attempts, 65 percent of expected goals (6.64–3.60)—yet lost 4–3. Chicago won on a heist.

New York out-attempted Chicago 47–24 and generated 12 high-danger chances to Chicago's 7. The numbers overwhelmingly favored the Islanders. Yet they underperformed their xG by 3.64 goals, while Chicago converted at a clip the underlying data didn't support.

Chicago's finishing was clinical: 3 goals on 7 high-danger chances (43 percent). New York managed just 2 on 12, a stark contrast to their possession dominance. High-danger efficiency decided this game.

A. Soderblom stopped 3.64 goals above expected on 47 shots—a dominant performance. I. Sorokin played respectably but couldn't overcome his team's inability to finish. D. Rittich, in relief, gave up 1.2 goals more than expected, a minor role in an otherwise uneven contest.

The turning point came early in the third period when Calum Ritchie's snap shot from the doorstep (16:37) gave Chicago the lead it would not relinquish.

Chicago's rush efficiency provided the edge. The Blackhawks converted 2 of 22 rush chances; the Islanders converted 2 of 46. Both teams created chances off the break, but Chicago needed fewer attempts to finish.

New York had every tactical advantage and surrendered the result.

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, 8:37 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 2.4–2.9 Chicago loss, favoring New York at 57% win probability. The Islanders dominate underlying play: their 48.0% expected goals share at 5v5 versus Chicago's 42.0% indicates they generate higher-quality scoring chances at a consistently higher rate. A 49.0% to 46.0% Corsi edge confirms New York controls possession.

Recent form complicates the picture. The Islanders are underwater at minus-6 goal differential over their last 10 games, while Chicago sits at minus-11. Both teams underperform their underlying metrics—a sign that neither has converted chances efficiently or benefited from lucky results. Chicago's deeper deficit suggests execution failures compounding their structural disadvantage.

Tyler Bertuzzi carries Chicago's scoring load at 0.85 expected goals per 60 minutes, translating to 20 goals and 15 assists with seven high-danger conversions. His 18.0% shooting rate leaves room for regression. Connor Bedard operates from a different role: 0.82 xG/60 yields 17 goals and 27 assists, indicating he distributes more than he scores, with an 11.8% shooting rate that lags behind volume scorers.

For New York, Anders Lee generates chances at 1.20 expected goals per 60 minutes—the highest on the sheet—yet has only nine goals and 20 assists on a 6.4% shooting rate, explaining why elite creation hasn't yielded elite scoring. Bo Horvat provides the finisher's profile: 0.87 xG/60 translates to 18 goals and 10 assists on 12.8% shooting, a conversion rate that outpaces Bedard.

Both teams face inefficiency in finish. Chicago shows 0% high-danger goal rate and 0% rebound goal rate, with Anton Frondell a defensive liability. New York mirrors this wasteful streak at 0% high-danger and 0% rebound rates, though Alexander Romanov represents their defensive weak link. Despite these finish problems, New York's underlying superiority holds. The model's 57% lean on the Islanders aligns with the evidence.
