The Bruins won 3–1 despite being outshot in expected goals 4.60–1.95. The Islanders controlled 70% of high-danger chances and dominated possession. This was a heist by Boston.

New York took 76% of shot attempts at 44–14. They led 6–3 in high-danger chances. But the Bruins converted theirs ruthlessly. A. Steeves scored the turning point at P3, 10:21, and Boston punished the rush: two goals on fifteen chances.

J. Swayman made the difference. He stopped 43 of 44 shots for a 0.977 SV%, finishing 3.60 goals above expected—the largest margin of the night. I. Sorokin faced 14 shots, saved 11 (0.786 SV%), and finished 1.05 goals below expected. The goaltending disparity decided the outcome.

New York wasted its dominance. The Islanders created eight rebound opportunities and converted none, failing to compound their edge. Boston's high-danger efficiency was surgical—the Bruins took their openings and finished.

The season numbers split 33 — no clear process edge — and PDO (1.023 vs 0.993) says BOS has run hotter.

The model projects a 2.5–2.7 goal game with the Islanders at 53% win probability. This is about as close to a pick'em as you'll find.

Start with what makes this even: Boston's 47.0% expected goals share and New York's 48.0% are separated by a rounding error. Corsi% lands at 49.0 for both. Neither team has a meaningful possession or chance advantage.

The variance lives in luck. Boston's PDO is 1.023—running hot on both shooting and save percentage. Expect some regression. New York carries a 0.993, suggesting they're converting below their underlying quality. In a game this tight, positive regression on the Islanders side becomes a tiebreaker.

The Bruins' scoring hinges on Viktor Arvidsson, posting 1.04 expected goals per 60 with 18 goals and 24 assists. His 13.0% shooting rate on 2 high-danger goals signals he's both generating and finishing at volume. Tanner Jeannot (0.75 xG/60, 6G 14A, 2 HD goals, 8.3% shooting) offers secondary punch without the same volume.

The Islanders counter with Anders Lee at 1.20 xG/60—the highest rate on the ice—backed by 9 goals, 20 assists, and 2 high-danger goals on a 6.4% shooting rate. That low conversion hints at untapped upside. Bo Horvat brings 0.87 xG/60 with 18 goals and 10 assists; his 12.8% shooting rate and 3 high-danger goals make him a genuine second-line threat.

Both teams mask defensive weakness. Boston's Elias Lindholm and New York's Alexander Romanov are soft spots. Neither team converts high-danger or rebound chances efficiently—both at 0%—which means the game pivots on transition efficiency and who stays cleaner in their own end.

The edge goes to New York on variance, but Boston's individual talent keeps this a coin flip.
