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

CGY 2 · NYI 3
◆ By the ModelJul 12, 7:22 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 3-2 in a game far more lopsided than the scoreboard suggests. New York generated 0.065 expected goals per shot versus Calgary's 0.041 — a decisive quality advantage that should have produced a blowout but settled for a one-goal result.

What kept it close was goaltending. D. Wolf (CGY) stopped all 17 shots he faced, saving 2.01 goals above expected — elite work that limited the damage. Earlier, D. Cooley (CGY) surrendered 1.8 goals more than expected in limited action, an early collapse that set the tone.

The Islanders held just 46% of shot attempts (27 on goal to Calgary's 32), proving volume was irrelevant. They accumulated 3 high-danger chances to Calgary's 2. S. Holmstrom epitomized this precision: 2 goals in 15:30, the game's most dangerous player by a wide margin.

Both teams converted their rush chances at nearly identical rates — New York 2 of 26, Calgary 2 of 28. The difference was execution up close. New York created 5 rebound opportunities and converted 1; Calgary couldn't finish the same way. D. Rittich (NYI) was steady (30/32 saves, +0.64 vs expected), sufficient to hold once Calgary's goaltending deteriorated.

The final score flattered Calgary's underlying performance. New York's shot quality was the actual deciding factor.

    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, 7:07 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 2.5-2.7 goal game with the Islanders at 53% win probability — a genuine toss-up.

    The Islanders are the hotter team by recent pace, going 7-3-0 over their last 10 games. Calgary, by contrast, has been underwater, sitting at -13 goal differential over the same stretch. That gap in form is real but not decisive.

    The advanced metrics barely separate these teams at even strength. Calgary's expected goals share sits at 47.0%, while New York edges ahead at 48.0%. Corsi tells the same story: both at 49.0%. Nothing here suggests a dominant team facing a weak one. Both are doing roughly the same thing on the ice.

    But Calgary's PDO of 0.985 tells an important story — this team is running cold and due for positive regression. That combination of tight margins and unsustainable luck makes them dangerous. When teams this evenly matched start catching breaks, the swings can be fast.

    The goaltending angle is worth watching. I. Sorokin is on a back-to-back, which could mean either a backup start or a tired starter playing through fatigue. Either way, New York's crease comes with a durability question.

    Calgary's Blake Coleman has been their engine at 0.89 expected goals per 60 with 16 goals and 12 assists. He's converting at 11.4%, which is sustainable. He has 2 high-danger goals, meaning he's not just lucky — he's in the right spots. He's the player the Islanders must neutralize.

    Matt Coronato offers 0.80 xG/60 and has 10 goals and 16 assists, though his 6.6% shooting rate suggests room for positive regression. He's the defensive weak link the Islanders should target.

    New York counters with Anders Lee at 1.20 xG/60 — the highest shot-quality rate on either roster — backed by 9 goals and 20 assists. At 6.4% shooting, he's both elite in chance generation and efficient in execution. Bo Horvat is the finisher, with 18 goals and 12 assists at 0.87 xG/60, converting at 12.8% and adding 3 high-danger goals.

    Alexander Romanov represents New York's defensive vulnerability.

    The tactical quirk: both teams are generating almost no high-danger or rebound goals, suggesting they're leaving goals on the table through either defensive discipline or finishing inconsistency. Whichever team breaks through that pattern first likely wins.

    This is a game where the team catching a break or getting a superior goaltending performance wins. The model has calculated that correctly.
