The Bruins had the better game on paper. Expected goals split 2.28–2.61 in Boston's favor—the underlying play suggested a Bruins victory. Instead, Calgary won 2-1 in overtime. D. Wolf made 25 saves at 0.962 SV%, outperforming expected goals by 1.61. The Bruins underperformed their xG by exactly 1.61 goals, a difference nearly matched by Wolf's goaltending excellence.

Connor Zary scored from the doorstep at 01:53 of overtime to supply the game-winner, but the story was set before then. Calgary held 45% of shot attempts (21–26 on goal), translating volume into high-danger looks: they generated 3 and buried 2 through crashing the net effectively. Boston also created 3 high-danger chances but converted none—costly in a one-goal game. J. Swayman (BOS) kept the Bruins close with a 0.950 SV% and 1.28 goals above expected, but Wolf's theft made the difference.

The model projects a 2.5–2.6 expected-goal game with Calgary at 52% win probability. This is a pick'em.

The Flames are the hotter team. They're 7-3-0 in their last 10 games, a run that projects toward playoff contention. Boston is minus-6 in goal differential over the same span—a signpost of deeper trouble. Yet the underlying metrics tell a different story: both teams own 47.0% expected-goals share and 49.0% Corsi percentages at 5v5. The talent is matched. The separation is luck. Calgary's 0.985 PDO reveals cold finishing and due-for-positive regression. Boston's 1.023 PDO cuts the opposite way: the Bruins are running hot and should expect natural erosion.

Both goalies face back-to-back starts. D. Wolf for Boston, J. Korpisalo for Calgary. Watch for either a backup or a weary starter.

Viktor Arvidsson is Boston's engine at 1.04 expected goals per 60 minutes, with 18 goals and 24 assists. His 13.0% shooting rate is real—he's not on a lucky streak. Tanner Jeannot supplies 6 goals and 14 assists at 0.75 xG/60. Calgary counters with Blake Coleman at 0.89 xG/60, 16 goals, and 12 assists. Matt Coronato adds 10 goals and 16 assists at 0.80 xG/60.

Boston's Elias Lindholm and Calgary's Coronato are defensive weak links. Both teams have converted just 0% of their goals from hard chances and rebounds—a statistical anomaly that will almost certainly regress.

The model calls it even because the talent is even. Calgary's form advantage is real, but Boston's luck should normalize and its underlying metrics remain strong.
