The Bruins won 3–2, but the Blue Jackets' underlying numbers told a different story. Columbus generated 4.13 expected goals against Boston's 3.62, held 61% of shot attempts, and still lost. The culprit: a catastrophic underperformance on their scoring chances. The Blue Jackets underperformed their xG by 2.13 goals—a chasm that doesn't close often.

Quality mattered more than volume. Boston squeezed 0.081 xG per shot compared to Columbus's 0.061, meaning the Bruins generated more dangerous looks despite being outshot. That edge materialized in net. J. Korpisalo (BOS) stopped 2.13 goals above expected, while J. Greaves (CBJ) was merely 0.62 above.

The Blue Jackets couldn't convert when it mattered. They went 0–5 on high-danger chances and were equally inefficient on the rush—2 goals on 36 chances. Boston, meanwhile, went 0–7 on high-danger opportunities, suggesting neither team was efficient in the dirty areas. But Boston was lethal enough on the rush: 2 goals on 26 chances.

Mark Kastelic's snap shot from a sharp angle (P3, 10:22) was the pivot. It gave Boston breathing room late and, given Columbus's wasteful performance, enough cushion to hold on.

The turning point wasn't dominance. It was Columbus doing everything right on paper and nothing right in execution—a reminder that possession and volume tell incomplete stories in hockey.

The model projects a BOS 2.4 - 2.8 CBJ game with CBJ at 56% win probability. Columbus dominates the underlying play — 52.0% xG, 51.0% Corsi% — but Boston's 1.023 PDO is running hot and regression is coming.

Columbus sits -11 in goal differential over the last 10, a warning that possession doesn't always translate. Yet its 52.0% xG% is real. Boston's defensive weak link is Elias Lindholm; Columbus's is Conor Garland. Mathieu Olivier is week-to-week with an upper-body injury.

The goaltending picture cuts both ways. J. Greaves and J. Swayman are both on back-to-backs, creating fatigue risk on both ends. Either could start a backup.

Boston's offensive burden falls to Viktor Arvidsson at 1.04 xG/60 with 18 goals and a 13.0% shooting rate. Mark Kastelic offers depth at 0.89 xG/60 and 10 goals. For Columbus, Boone Jenner is the engine at 0.98 xG/60 with 11 goals, playing at a 9.6% conversion clip. The gap between his efficiency and Arvidsson's is the game.

Boston's PDO anomaly — 1.023 — makes regression the underlying story. The Bruins are running hot; the Blue Jackets are playing better.

Three Things to Watch

• Columbus's 52.0% xG advantage is durable and the model's edge.
• J. Greaves is on a back-to-back; watch for a backup or tired starter.
• J. Swayman is on a back-to-back; watch for a tired starter.
