◆ By the ModelJul 12, 11:02 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

L. Ullmark's elite night—1.63 goals saved above expected—reveals why Ottawa's 5-1 win outpaced the underlying battle. The Senators controlled 63% of expected goals (4.42–2.63). But Ullmark's 0.957 SV% (22/23) combined with Florida's 1.63-goal underperformance created a two-part gap that inflated the margin. In hockey, that's how variance converts competitive into decisive.

Fabian Zetterlund's wrist shot from the high slot (17:02 of the third) was the turning point—when Ottawa's quality edge became inescapable.

The rest followed the underlying advantage. Ottawa generated 10 high-danger chances to Florida's 3. The rush game was lethal (3 goals on 23 chances). J. Sanderson (2 assists, 22:22), F. Zetterlund (2 goals, 11:48), and A. Zub (1 goal, 22:32) embodied the depth of Ottawa's control.

S. Bobrovsky's 21/25 night (0.840 SV%) doesn't indict his performance. On high-danger shots, he was solid (90% SV on 10). The problem was volume and placement—when facing 25 shots tilted toward quality ice, even sharp goaltending surrenders goals in volume. Florida's underlying structure held; the gap came from execution on both ends.

    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, 11:21 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 FLA 2.3 - 2.7 OTT game with the Senators at 58% win probability.

    Ottawa is the hotter team by points pace—6-3-1 in their last 10 matches versus Florida's underwater -13 goal differential over the same span. But the gap between these teams exists not in recent form but in the underlying possession game.

    The Senators own the 5v5 battle decisively. Ottawa holds a 56.0% expected goals share against Florida's 49.0%—a 7-point edge that reflects consistent dominance in shot quality. The advantage narrows slightly on gross volume: Ottawa's Corsi% sits at 53.0% to Florida's 52.0%. Yet the Senators' PDO of 0.993 versus Florida's 0.989 signals sustainable execution rather than variance.

    Players to Watch

    Florida

    • Sam Bennett — 0.97 xG/60, 18G 19A, 6 HD goals, 13.1% shooting
    • Brad Marchand — 0.93 xG/60, 17G 9A, 3 HD goals, 19.5% shooting

    Ottawa

    • Brady Tkachuk — 1.19 xG/60, 11G 20A, 2 HD goals, 7.5% shooting
    • Dylan Cozens — 1.00 xG/60, 13G 15A, 1 HD goals, 9.5% shooting

    Neutralizing Sam Bennett is Ottawa's first priority; the key matchup hinges on containing a player at 0.97 xG/60 generating consistent volume. Brad Marchand's 19.5% shooting warrants watching—that conversion rate rarely holds. For Florida, Brady Tkachuk presents the tougher assignment at 1.19 xG/60, while Dylan Cozens handles secondary offense without volatility.

    The tactical reality cuts cleanly. Both teams operate at 0% hard-chance goal rate and 0% rebound rate—discipline paired with brittleness that rewards possession control. Nick Jensen is a defensive weak link for Ottawa. When two teams are equally dependent on primary scoring, the team dictating terms through superior underlying play carries the larger advantage. That's Ottawa.
