◆ By the ModelSep 25, 1:00 AMxG: xgboost-0.765Edited 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

Toronto beat Ottawa 4-2 on a night when the quality of chances diverged sharply from the shot count. The Maple Leafs found the dangerous areas; Ottawa did not.

Where they won: expected goals. Toronto generated 3.52 against Ottawa's 1.67, a ratio that left little doubt about who played the better game. The Maple Leafs controlled 68% of expected goals while holding only 47% of shot attempts—a 21-point gap between shot share and quality share that captures the full performance.

Toronto created six high-danger chances; the Senators created one. That disparity came from both offense and defense: the Maple Leafs attacked the high-danger areas while Ottawa's transition defense leaked chances on the rush. V. Lettieri and M. Rifai both assisted on plays that exposed those weaknesses.

The scoring reflected it. H. Rybinski opened the game from 6 feet on a rebound, then S. Lorentz tipped one in from the slot (another 6-footer). R. Tverberg snapped one from distance, and T. Blueger finished into an empty net. The power play cashed in once. The rush game worked twice.

Goaltending told its own story. A. Stolarz made 19 saves on 21 shots for Toronto. L. Ullmark made 20 saves on 23 for Ottawa, stopping 0.52 expected goals above what the model projected—a strong night in a lost cause. The Senators scored twice on 18 rush chances, but that aggression cost them: Toronto gave up 23 rush shots worth 2.35 expected goals, gaps that appeared every period.

The goals

  • TOR 1–0, 03:51 of the second on the power play. H. Rybinski, snap shot from 6 feet, a 20% chance by the model (a rebound), past L. Ullmark. Assists: V. Lettieri, N. Blankenburg. 1 second after a TOR shot by V. Lettieri. Win probability moved 20 points.

  • TOR 2–1, 10:01 of the third. S. Lorentz, tip-in from 6 feet, a 10% chance by the model (off the rush), past L. Ullmark. Assists: M. Rifai, B. Duhaime. Win probability moved 33 points.
  • OTT 2–2, 10:42 of the third. H. Stanley, backhander from 12 feet, a 19% chance by the model (off the rush), past A. Stolarz. Assists: T. Hamara, C. Giroux. Win probability moved 34 points.
  • TOR 3–2, 15:43 of the third. R. Tverberg, snap shot from 26 feet, a 17% chance by the model, past L. Ullmark. Assists: J. Quillan, B. Smith. 6 seconds after a TOR shot by J. Quillan. Win probability moved 40 points.
  • TOR 4–2, 19:52 of the third into an empty net. T. Blueger, snap shot from 62 feet, a 1% chance by the model. 2 seconds after an OTT giveaway by B. Hutton.

What the numbers can't tell you. Whether the finishing was luck or skill, why the benches were run the way they were, who was hurt, and anything said in the room. That is the beat's story, and it is worth reading.

    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.
