Penguins at Blackhawks, Dec 28, 2025: who deserved to win?

The Penguins beat the Blackhawks 7–3, but the replays call it close to a coin flip: with the way both teams played, the Penguins win 5 of 10. Luck ran their way: goaltending alone was worth 30 points of win probability to the Penguins.

The biggest swing (P1, 18:22 left): Anthony Mantha scored on a wrist shot from 14 feet, worth 14 points of win probability to the Penguins.

Where the luck was

What the luck was worth

Every lucky and unlucky play, weighted by the moment it happened: its swing in win probability, added up by kind. A post hit in a blowout counts for nothing; the same post with a minute left in a tie game can be most of a win.

Swings add up across a game, so in one that went back and forth they can pass 100%. On the scoreboard the same luck was worth +3.5 goals to the Penguins: the final margin was Penguins by 4, without the luck Penguins by 0.5. Luck shares are the fitted ones (how much of each kind is luck).

Regulation with both goalies in. Expected goals: our model of each shot’s chance from where and how it was taken (distance, angle, shot type, rebound, rush, strength), adjusted for the shooter’s and the goalie’s records. A team above expected finished better or met a weaker night in goal; 75% of the gap counts as luck (why that share).

Calls

Every penalty that put a team on the power play, and every goal taken off the board on review, with what it did to the helped team’s chance of winning at that moment. Calls don’t count toward luck by default: who draws penalties repeats from game to game like a skill (how calls are valued). Switch them on below.
