Moving Devizier's post from the Sixers thread over here because he said similar things to you.Did Bowiac leave the Cellar? He would be the person to ask about DARKO
In NBA analytics, "Daily Plus-Minus" (often referred to as "DPM" or "DARKO") is a more advanced metric that calculates a player's impact on the game by considering not just their basic plus-minus, but also factors like recent performance, opponent quality, and situational context, using complex statistical models like "Kalman filters" to weight recent data more heavily and provide a more predictive measure of a player's daily impact on the game
DARKO, aka Daily Plus-Minus or DPM, is created by Kostya Medvedovsky. DARKO (stands for “Daily Adjusted and Regressed Kalman Optimized“) is a composite predictive metric that uses box score and plus-minus stats. By blending these components in proportion to the number of total possessions of a player, recent performance is weighted more heavily to better predict future game outcomes.
(On-Court & On-Off) make up +/- per 100.
1. Your teammates will affect your On-Court number
2. How well you play relative to your teammates will be reflected by On-Off
Over time they will start telling you how well the team fares on Defense, on Offense, & Overall when a player is playing or not playing.
It's been my contention for a while that Brad was chasing Derrick White & not Dejounte Murray (even though DM was much more decorated). White's On-Court & On-Off dwarfed Dejounte when they played for the Spurs.
Also, I don't think DARKO clears out garbage time minutes. Haven't people said that the Cs garbage time units haven't been fairing very well? If that's true, then as the leader of the garbage time minutes, PP's defensive numbers would certainly take a hit.
It might affect some numbers; but I think DARKO is more sensitive to who you share the floor with (and play against).
A decline in defensive performance could indicate that
1) He is playing against more offensively capable first units and his defense looks worse by comparison
2) He’s in worse lineups overall (defensively) compared to past seasons
3) He’s actually performing worse on defense, perhaps in ways that are not immediately obvious
I honestly can’t say which, he seems pretty much the same defensively to my eyes, so I’d lean towards 1/2
