What are Pythagorean wins in hockey?
The Bill James concept with hockey's simplest exponent: 2, which makes the formula exactly the Pythagorean theorem shape. Goal differential is a stronger predictor of future points than standings points, especially before Christmas.
How the calculator works
Enter goals for and against; the tool returns expected wins and the implied differential. Expected points ≈ expected wins × 2 for a quick standings translation.
Common use cases
- Spotting hot-goalie mirages in November
- Trade deadline buyer/seller reads
- Goal-differential arguments with receipts
Formula & caveats
Hockey's low scoring makes single-game variance high — expect larger record-vs-differential gaps than in basketball.
Frequently Asked Questions

Does goalie quality matter?
It is inside the numbers already — great goaltending shows up as low goals allowed.
Expected points vs expected wins?
Multiply expected wins by 2 and add a typical OTL share for a points estimate.
