About
Proving your team got robbed, with data.
What is CURSD?
CURSD is the definitive source for measuring luck in sports. We rank every team across the Premier League, La Liga, Ligue 1, NHL, NBA, and MLB by how much fortune - good or bad - has influenced their season.
The Luck Index combines expected goals (xG), Pythagorean expectation, and real match signals into a single score from -100 to +100. Negative means unlucky. Positive means lucky. It's that simple.
Who is this for?
- Fans who know their team is better than the standings suggest (and want the data to prove it).
- Fantasy players looking for regression candidates - teams due for a bounce-back or a fall.
- Bettors who want to identify mispriced teams based on underlying performance vs results.
- Anyone who enjoys sports analytics and wants a fresh lens on the season.
How it works
Every sport has a way to measure what should have happened vs what actually happened. We use established models - xG for soccer, Pythagorean expectation for hockey and basketball - and layer in match-level signals to build a composite luck score.
Data is updated daily from free, publicly available sources. For the full technical breakdown, check the Methodology page.
