Boston won 4–2 despite controlling just 38% of expected goals. Superior goaltending and Seattle's inability to finish decided the game.

The xG split was 2.36 for Boston, 3.86 for Seattle. At 5v5, Seattle commanded 62% of the expected-goal share. The Bruins scored two goals from low-danger spots—exactly the kind of chances an opposing goalie needs to stop. J. Swayman made 26 saves on 28 shots, stopping 1.86 goals above expected. That's not luck; that's theft.

Boston's scoring model was rush-heavy: three goals on 19 rush chances, an elite conversion rate that masks a deeper problem. Outside the rush, the Bruins shot into a storm—just 24 shot attempts to Seattle's 28—and the danger levels didn't match their finish. The Kraken created four rebound opportunities, converting one, which suggests a team that understood how to generate second chances. They just couldn't put them away.

For Seattle, J. Daccord stopped 20 of 23 shots but underperformed his expected total by 0.64 goals. High-danger chances finished even at 3–3, meaning Seattle did the difficult work and got nothing for it. Their power play was the only outlier: 2 goals on 18 shots, with 1.95 xG—genuine dominance rendered meaningless in a loss.

BOS holds 5 of 6 process categories — and PDO (1.011 vs 1.023) says BOS has run hotter.

Source · MoneyPuck season tables · 5v5

The model projects a 2.4–2.6 expected-goal game with the Bruins at 53% win probability. This is about as close to a pick'em as you'll find.

Boston's territorial edge is substantial: 49.0% Corsi to Seattle's 45.0%. That creates offensive volume. But underlying shot quality is nearly identical—Seattle's 46.0% xG% sits a point behind Boston's 47.0%, so the Kraken can win if they finish their chances.

The Bruins are running hot on conversion. Their 1.023 PDO indicates unsustainable finish; Seattle's 1.011 is near average. In a tight game, regression odds favor Seattle.

Viktor Arvidsson drives Boston's offense: 1.04 xG/60 with 18 goals and 13.0% shooting, elite on volume and finishing. Tanner Jeannot supplies secondary punch at 0.75 xG/60, 6 goals, 8.3% shooting. Seattle counters with Shane Wright (0.77 xG/60, 8 goals, 10.4% shooting) and Berkly Catton (0.68 xG/60, 6 goals, 8.8% shooting). The scoring talent is leveled.

Defensively, Chandler Stephenson is Seattle's weak link; Elias Lindholm is Boston's. Neither team is scoring from high danger—both at 0% high-danger goal rate—so this comes down to goaltending luck.

J. Swayman faces a back-to-back. If he plays tired, Seattle improves. If Boston uses a backup, Seattle must capitalize.

This is a coin flip. The Bruins' 53% edge is real but razor-thin.
