Adjusted Plus-Minus (often abbreviated APM) is a basketball analytic that attempts to predict the impact of an individual player on the scoring margin of a game by controlling for the rest of the players on the court at any given time. The metric is derived using play-by-play data to keep track of all substitution and possession ending actions. It was first implemented by the Dallas Mavericks in the early 2000s after owner Mark Cuban commissioned data scientists Jeff Sagarin, Wayne Winston, and Dan Rosenbaum, who developed the metric alongside their WINVAL conversion to aid in player salary determination.[1] In combination with other innovations, this gave the Mavericks one of the most progressive front offices in the league at the time. Since APM's creation several derivative metrics attempting to improve on the skeleton have been created.[2]
