Across two continents, three leagues, and two sports, five teams are bound by a shared, quiet humiliation: the underlying numbers insist they should be better than this. Pisa, the Brooklyn Nets, Athletic Club, Hellas Verona, and Metz have all spent the current season watching their results betray their process. The CURSD Luck Index, which measures the gap between observed outcomes and statistical expectation, flags all five as extreme negative outliers. None of them chose this. None of them can explain it away.
Here are the five unluckiest teams in world sport right now.
1. Pisa - Serie A
Pisa's Luck Index of -75 is the worst in our global database this week, and the gap is not subtle. They have accumulated 18 points from 33 Serie A matches. Their expected points total, derived from match-level xG models, sits at 35.1. That is a 17.1-point deficit, roughly the difference between relegation and midtable comfort.
Their record reads 2W 12D 19L, and those 12 draws are the skeleton key. Pisa have been competitive enough to avoid losing cleanly in a third of their matches, but they have converted almost none of that competitiveness into victories. In games decided by a single goal, they have been on the wrong side of the result with remarkable consistency.
Twelve draws and two wins from 35.1 expected points is not a team failing. It is a team being failed.
2. Brooklyn Nets - NBA
The Nets' season is over, which at least means the bleeding has stopped. Brooklyn finished 20-82, a record that looks like organizational surrender. The Pythagorean expectation, based on points scored and allowed across the full season, projected roughly 26 wins. Six games does not sound like much until you remember that six wins is the difference between historically terrible and merely very bad.
Brooklyn lost 62 games. A nontrivial number of those were close. Their Luck Index of -70 reflects a team that was outscored by margins consistent with a 26-win pace but finished games like a 20-win one. Crunch-time execution, or the absence of it, does not always reflect talent. Sometimes the ball just doesn't go in.
3. Athletic Club - La Liga
Athletic's inclusion here might surprise anyone who thinks of them as a robust, well-coached side. They are. That is precisely the problem. Ernesto Valverde's team has generated 48.4 xPoints from 31 La Liga matches but holds only 38, a shortfall of 10.4 points that has quietly dragged them from European contention toward the middle of the table.
Their 11W 5D 15L record includes a string of defeats in matches where they created the better chances. Athletic are not being outplayed. They are being outfinished, which is a different kind of frustration, the kind where the process offers no obvious fix.
4. Hellas Verona - Serie A
Verona's 18 points look identical to Pisa's, but their expected points total of 39.3 makes the gap even wider in raw terms: a 21.3-point chasm, the largest on this list. Their Luck Index is lower than Pisa's only because the model weighs context and variance slightly differently, but make no mistake, Verona's season has been a statistical catastrophe.
Three wins from 33 matches for a team generating nearly 40 expected points is the kind of number that makes analysts check their data twice.
5. Metz - Ligue 1
Metz sit bottom of Ligue 1 with 15 points from 30 matches, a record of 3W 6D 21L that screams relegation. The expected points model is more generous: 28.0, which would place them significantly closer to safety. A Luck Index of -59 rounds out the bottom five.
Thirteen points of negative variance has turned a struggling team into a doomed one. Metz have conceded late goals, dropped points from winning positions, and watched narrow xG advantages evaporate into defeats. The margins in Ligue 1's lower half are thin, and Metz have been on the wrong side of nearly all of them.
The Common Thread
What connects Pisa, Brooklyn, Athletic, Verona, and Metz is not poor defending or weak schedules. It is finishing variance, both their own and their opponents'. These are teams losing the conversion battle, watching chances created translate into fewer goals than expected and chances conceded translate into more. The models say regression should come. For some of these teams, the season will end before it does.
