Yep, this is a bull stat.
No ESPN started with RAPM last season. RPM is their re-brand so to speak but it's the same guy:
RPM stats are provided by Jeremias Engelmann in consultation with Steve Ilardi. RPM is based on Engelmann's xRAPM (Regularized Adjusted Plus-Minus). Play-by-play data provided by
Like all stats context is key and one stat shouldn't stand alone. Using several good ones combined with a solid eye-test is the best chance of a good picture.
Standing alone RPM like everything else standing alone will have some silly outliers in the form of some bad player rating incredible or a more or less poor one falsely showing up with the elite, but for the sake of argument standing alone I do think historically its the one stat that best reflect getting the top players that contribute the very most to winning rated the most right.
Tim and Manu have been crushing it consistently for years being among the very very best players in the league http://stats-for-the-nba.appspot.com/ .
Parker often when it comes to many advanced stats has also been hurt by not shooting threes. It's pretty gross though that this current season he is this low compared to many others.
It's still early though and many things will change. Some are way too high this early and some will make up ground.
So basically Tim is an immortal God, Kawhi is already the best SF in the league, and we're going to have to find a way to get Danny max money this off-season? And oh yeah, lol parker.
Does that sum it up?
The problem with this stat is that players in better teams are likely to get better +/- so it's not perfect... but then again, no stat is or will be, so I guess you could always use the argument "lol at this stat", because, yeah, sure, they are always a simplification of reality. What would be fair is to compare this stat with other stats and, in that sense, I think it's an improvement.
I was sort of under the impression that it was essentially the same stat. From the ESPN article introducing it:
Real plus-minus (RPM) was developed by Jeremias Engelmann, formerly of the Phoenix Suns, in consultation with Steve Ilardi, University of Kansas psychology professor and former NBA consultant.
It follows the development of adjusted plus-minus (APM) by several analysts and regularized adjusted plus-minus (RAPM) by Joe Sill.
RPM reflects enhancements to RAPM by Engelmann, among them the use of Bayesian priors, aging curves, score of the game and extensive out-of-sample testing to improve RPM's predictive accuracy.
Engelmann was the guy who provided xRAPM stats (the ones people saw on the stats-for-the-nba website) prior IIRC. Like someone said above, I think ESPN just sort of rebranded it.
what about platoon players who sub in on defense? Won't they be gyped?
Indeed...
Didn't see the "Parker is expandable" since George Hill sop re year!!
We got some creative mother ers on this board!![]()
ESPN seems to be updating PRM daily.
Don't see some Parker suckers here.. I wonder why
