NBA analytics glossary
Every metric this API returns, with the formula, what it is for, and the specific way people get it wrong. Written from how these are actually computed here, not paraphrased.
Field goal percentage with a made three counted as 1.5 makes, so a team that shoots threes is not undersold.
Points scored per shooting possession, counting twos, threes and free throws in one rate.
The points a shot is worth on average, from where it was taken and what kind it was, fitted on league history.
Six areas of the floor, from the restricted area to the free throw line, used to summarize where a player or team shoots.
An estimate of how many times a team had the ball, built from box score counts since the game does not log them.
How many possessions a team plays per 48 minutes. It describes tempo, not quality.
Points scored minus points allowed per 100 possessions. The standard single number for team strength.
Shooting, turnovers, rebounding and free throws: the four team numbers that explain most of the difference between winning and losing.
Our team rating, updated after every game from the score and where it was played, and pulled toward average each offseason.
The chance a team wins, given the score, time left and who has the ball, recomputed on every play.
The last five minutes of the fourth quarter or overtime with the score within five points.
The edge a team gets at home, which both the market and our ratings price in as a fixed number of points.
The win chance a moneyline price states, once converted from American odds to a percentage.
A sportsbook's last posted price before tip-off, the standard yardstick for whether a bet was a good one.
How a sportsbook's spread, total or moneyline changed between the time it was posted and tip-off.
Whether a team won by more than the point spread, so a loss can still be a cover and a win can still be a miss.
