Where the numbers come from and what they are not.
Game, box-score, play-by-play and shot data come from the hoopR / sportsdataverse release files, published under the Creative Commons Attribution 4.0 license. The underlying data originates at ESPN.
Changes made: Stats Pirates loads those files into its own database, matches players and teams across seasons, and computes rates, splits and the modeled measures below. Nothing here is an official NBA statistic, and the NBA does not endorse this site.
Expected field goal percentage (xFG) and shooting over expected are modeled by Stats Pirates from shot location, shot type and game situation. They are not NBA player-tracking data, and they do not see defenders, shot clock or release.
A season is named by its ending year, so 2026 is 2025-26.
