How Saabi predicts NBA games

Saabi is a free NBA prediction model. Here is what goes into every pick, and how you can check it.

The data

Every NBA box score for five seasons, every team's lineups and minutes, injuries and who's out tonight, rest and travel, and the betting market's prices from the sharp books and the US books, refreshed through the day.

Team strength

Ratings that update after every game (Elo, Glicko, Bradley–Terry, Massey, adjusted efficiency and more), each weighted toward this season and adjusted for home court, back-to-backs and travel.

The game, played out

Saabi simulates each game thousands of times possession by possession, which gives the win chance, the projected score, and the chance of covering the spread or going over the total.

Player props

Each player's projection comes from his minutes, usage, recent form and the defence he's facing, checked with Poisson and negative-binomial curves for counting stats like rebounds, assists and threes.

500+ models, blended

Statistics, machine learning, neural nets, Bayesian models and market models each give their own chance; a stacked ensemble weights them by how well each has done, and only trusts them over the market once they've earned it.

Graded in public

Every pick is recorded before tip-off and graded after the game, wins and losses alike, on the record page. Saabi also checks whether its picks beat the closing line, the surest sign of a real edge.

Play, don't pay

Saabi is a free prediction game: you play with points that have no cash value. Nothing here is betting advice; if you bet, bet responsibly.
