DRIP, just another new derivative of NBA plus-minus metrics that tries to project player contribution to +/- per 100 possessions on both offense and defense.
DRIP specifically uses adjusted +/- values and generates results as ‘DRIP on offense’, ‘DRIP on defense’, and ‘total DRIP’.
DRIP calculation is very similar to PIPM and DARKO DPM: box score data, play-by-play data and lineup data are being used to predict a player’s offensive and defensive impact. It’s not an average in a season or career, it’s an estimate of a player’s individual performance for each stat.
DRIP ratings for current season can be viewed on Stats-Perform blog.
