Plus-Minus, a.k.a. +/-, simply keeps track of the net changes in the score when a given player is either on or off the court. The NBA has been publishing plus-minus values in official box scores since the 2007-2008 season. A variety of combinations including the best two-player, three-player unit, and even five-player combinations for each game can be provided with the plus-minus technique.
Plus-Minus Calculation
Plus-Minus for Any Player=(Team Points Scored While That Player is On The Court) – (Team Points Allowed While That Player is On The Court)Relying solely on plus-minus is a huge mistake so, some analytical minds have developed and tried to reduce the +/- flaws in an effort to get more accurate results regarding a player’s impact. Currently, different types of plus-minus metrics are being published and here’s a collection:
