How these rankings work
Attack and defense, rated apart
Every team carries two ratings, both in points against a league-average opponent: an attack rating for the points it scores above average, and a defense rating for the points it prevents below it. Overall is the two added together, so a team rated +7 would be expected to beat an average team by about seven on a neutral court.
Adjusted for the opponent
After each week, both ratings move on their own error — what the team actually did against what the model expected, given the opponent's ratings and home court. Beating a good defense counts for more than beating a poor one, which is why these rankings and the standings disagree: a win-loss record can't tell a hard schedule from an easy one.
Blowouts count, not double
Margins are damped, so a 40-point win says more than a 15-point win without saying nearly three times as much, and ratings carry into a new season at half weight — last year is evidence, not gospel, once a roster has turned over. Win probabilities come from the rating gap and the historical spread of NBA results, rather than from simulated games.
How accurate is it?
Replayed week by week over 7,930 games in 2021–2027, predicting each week from only what it knew beforehand — against always backing the home team.
Brier score measures how well-calibrated the probabilities are, not just whether the pick was right — 0 is perfect, 0.25 is a coin flip, lower is better. Recalculated every week across every completed game, so it includes the season in progress.
