Kings at Avalanche, Dec 29, 2025: who deserved to win?

The Avalanche beat the Kings 5–2, and the replays lean their way: with the same day's form, they win 6 of 10.

The biggest swing (P2, 6:39 left): Martin Necas scored on a backhand shot from 5 feet, worth 20 points of win probability to the Avalanche.

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 +1.3 goals to the Avalanche: the final margin was Avalanche by 3, without the luck Avalanche by 1.7. 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.
