The Islanders earned it — the game and the expected-goals battle both.

◆ By the ModelJul 11, 12:32 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

New York's 4–3 victory conceals a deeper truth: the Islanders created significantly more dangerous looks than the Sharks, yet nearly squandered the advantage through underperformance.

The underlying metrics tell a clearer story than the scoreline. New York generated 10 high-danger chances to San Jose's 5—a 2-to-1 dominance in the categories that matter most—while producing 0.096 expected goals per shot attempt, compared to San Jose's 0.059. That quality differential translated to a 4.97–4.01 expected-goals edge (55 percent to 45 percent).

Both teams underperformed their xG. New York fell short by 0.97 goals; San Jose by 1.01. Yet both goaltenders ran hot: I. Sorokin saved 1.01 goals above expectation on 33 shots (0.917 SV%), while Y. Askarov returned a near-identical +0.97 mark on 23 saves (0.852 SV%).

New York's advantage stemmed from execution: 2 rush goals on 19 attempts, and a power play that converted 2 on 13 shots (1.84 xG). San Jose answered with 3 rush goals on 33 attempts, but never closed the high-danger gap.

The inflection came at 10:16 of the third period, when Macklin Celebrini's wrist shot from the high slot cut the lead to one.

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, 12:31 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 sees this as a coin flip. San Jose projects to score 2.5 to 2.6 goals; the Islanders are given 52% win probability—as close to a pick'em as you'll find.

New York has fresher legs. They've posted a 4-5-1 record over their last 10, a points-pace edge that looks meaningful. But the Islanders are underwater at -8 goal differential over that span, a sign their wins have been tighter or losses uglier. San Jose is worse at -16, suggesting deeper scoring troubles.

At even strength, both teams look equivalent. Each carries a 48.0% expected goals share; the Islanders edge the Sharks in shot attempts at 49.0% Corsi to 47.0%, a thin advantage. The Sharks' 0.998 PDO sits fractionally ahead of New York's 0.993, a gap that could evaporate with variance. On paper, these are matched teams.

The difference will come down to execution, particularly up front. Pavol Regenda was tracking as a major threat with a 1.10 expected goals per 60 rate and 16.1% shooting, but he's marked as likely inactive. Without him, Igor Chernyshov becomes San Jose's primary offensive engine—six goals, eight assists, and an elite 15.0% shooting rate.

The Islanders counter with two proven producers. Anders Lee has compiled nine goals and twenty assists while sustaining a 1.20 xG/60 rate, suggesting he's a premium volume player despite his 6.4% shooting sitting below league average. Bo Horvat has registered eighteen goals and ten assists, a total that speaks to genuine offensive merit—his 12.8% shooting isn't a mirage.

Igor Chernyshov is a defensive weak link for San Jose; Alexander Romanov for New York. Both teams have posted 0% rebound goal rates and 0% high-danger-chance conversions, an unusual pattern that suggests neither is generating second-chance opportunities at the league's typical rate. In a matchup this close, defensive miscues and second chances will decide it.
