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

NYI 5 · OTT 4
◆ By the ModelJun 16, 3:00 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 survived a relentless Ottawa offensive — the Islanders won 5–4 despite ceding 58% of shot attempts. The reversal lay in efficiency: New York generated 4.53 expected goals against Ottawa's 3.45, claiming 57% of underlying scoring chances while firing fewer shots.

Quality over volume tells the story. New York's shots averaged 0.091 xG each; Ottawa's 0.057. High-danger chances favored the Islanders 8–3, a gap the final score barely captures.

Both teams exploited the rush. Ottawa scored 4 goals on 27 rush attempts; New York scored 5 on 24 — a slightly more efficient edge that decided overtime. Neither team converted rebound opportunities, leaving Ottawa's 6 created and New York's 3 unconverted on the board.

Ottawa's power play was devastating: 2 goals on 11 shots, 0.71 xG. New York had no such edge, relying on even-strength dominance. Goaltender I. Sorokin absorbed the assault, stopping 28 of 32 for a 0.875 save percentage (–0.55 vs expected). L. Ullmark made 18 of 23 for Ottawa, a 0.783 mark in a losing effort.

The turning point arrived early in the third: Anders Lee's wrist shot from the slot at 18:57. Lee finished with 2 goals and 1 assist in just 13:25, a small volume with outsized impact. T. Chabot recorded 2 assists for Ottawa in 19:47; T. Stützle added 1 goal and 1 assist in the same span — enough offensive output to threaten, not to overcome.

New York won where it mattered: converting chances that actually threatened the net.

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 ModelJun 16, 2:59 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 favors Ottawa. A projection of 2.3 to 2.8 goals gives the Senators 59% win probability—a clean lean on a team that dominates 5v5 play.

Both squads have stumbled lately. New York has surrendered a goal differential of minus-10 over the last 10 games; Ottawa worse at minus-15. That's the puzzle: the team with superior underlying metrics is the one hemorrhaging results.

Where Ottawa's edge lives is clear. At 56.0% 5v5 expected goals against 48.0%, the Senators control shot quality decisively. Possession follows: 53.0% Corsi means Ottawa wins the territorial tilt. Both teams register 0.993 PDO, so neither can blame the puck luck—the underlying play is simply not variance.

Anders Lee is New York's offensive fulcrum. He generates 1.20 expected goals per 60 minutes with 2 high-danger goals, yet his 6.4% shooting rate has limited him to 9 goals and 20 assists. Bo Horvat is more efficient: 18 goals on 12.8% shooting and 3 high-danger goals, though his 0.87 xG/60 suggests overperformance against his opportunities.

Brady Tkachuk drives Ottawa's attack. At 1.19 xG/60 with 11 goals and 20 assists, he mirrors Lee in shot quality but edges ahead in conversion. Dylan Cozens represents Horvat's archetype: 13 goals at 9.5% shooting from 1.00 xG/60, though only 1 high-danger goal among them—a high-volume scorer punching above his opportunities.

New York's defensive soft spot is Alexander Romanov; Ottawa's is Nick Jensen.

Three Things to Watch

  • Ottawa's 56.0% to 48.0% xG advantage—the game's entire narrative
  • The 53.0% Corsi disparity tilts territorial control decisively toward the Senators
  • Ottawa's minus-15 recent differential collides with dominant underlying play—one of these regresses
