The verdict · stolen

The Bruins stole one. They lost the expected-goals battle 3.51–2.82 and won anyway.

NYI 2 · BOS 5
◆ By the ModelJul 11, 1:30 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

Boston won 5-2 against New York despite being outplayed. The Islanders controlled 55% of expected goals at 5v5, finishing with a 3.51–2.82 xG advantage—a heist.

Goaltending determined the outcome. J. Korpisalo stopped 1.51 goals above expected, posting a 0.943 SV% on 35 shots. I. Sorokin allowed 1.18 goals above expected on just 21 saves, a 0.810 SV%. One stole the show; the other folded.

Boston's finishing was ruthless where it counted. They scored two goals from low-danger spots—the kind opposing goalies are supposed to save—and converted five of 26 rush opportunities into goals. Their power play was dominant: two goals on 11 shots (0.93 xG).

New York scored twice on 27 rush attempts but wasted five rebound opportunities and underperformed their 3.51 xG by 1.51 goals. A collapse in goaltending compounded the issue.

Boston held 39% of shot attempts (22–35 on goal) and dominated high-danger chances 5–2. Fraser Minten's wrist shot from the high slot, 16:37 into the third period, was the turning point—it shifted momentum permanently.

The Bruins overperformed their expected goals by 2.18, a stark reminder that elite finishing punishes poor execution. New York played the better game on paper—controlled possession, created quality chances, spent time in dangerous ice. Then finishing and goaltending cost them everything.

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, 1:28 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 52% win probability for the Bruins in a 2.6–2.7 game — about as close to a pick'em as you'll find.

The Islanders are the hotter team, running 5–3–2 over their last ten. Boston sits at minus-10 goal differential in the same stretch, suggesting underlying issues the record hasn't yet caught up to.

The season numbers paint a near-identical picture at 5v5. New York's expected goals percentage is 48.0% to Boston's 47.0%; they're matched at 49.0% Corsi. Where they diverge is PDO — the Bruins are at 1.023, the Islanders at 0.993. Boston's bouncing upward; that gap typically closes on the next 20 games.

The Bruins come in on one day of rest, the Islanders on three. J. Swayman faces a back-to-back; watch for a backup start or a noticeably fatigued starter.

The Players

Anders Lee drives the Islanders: 1.20 expected goals per 60 minutes, 9 goals and 20 assists, two high-danger chances, 6.4% shooting. Bo Horvat is more efficient — 0.87 xG/60 but 18 goals and 10 assists with three high-danger goals and 12.8% shooting, well above team norm.

Viktor Arvidsson anchors Boston's offense. He's at 1.04 xG/60 with 18 goals and 24 assists, two high-danger goals, and 13.0% shooting. Tanner Jeannot runs a leaner line — 0.75 xG/60, 6 goals, 14 assists, two high-danger tallies, 8.3% shooting.

The defensive weak points: Alexander Romanov for New York, Elias Lindholm for Boston.

This is what a true toss-up looks like — the model's uncertainty is honest. The Islanders own the recent form and the rest edge; the Bruins own the unsustainable luck. Expect neither team to play unexpectedly well or poorly.
