I just saw this post (https://www.reddit.com/r/nbadiscussion/comments/1aextmx/new_lifetime_rapm_rankings_1997_includes_playoffs/), which mentioned Engelmann has shared some new career RAPM!

OG tweet:
RAPM is RS + PS
"Please note
- the possession parser hasn't yet been fully debugged
- 'season' is the only adjustment
- it's missing rubber-band and age adjustments, both of which would heavily infl. e.g. Jordan's rating"
This is especially exciting, since neither of the traditional RAPM sources (Goldstein or Engelmann) have published RAPM for the recent seasons.
Some notable ranks in Total RAPM:
Some notable ranks in Offensive RAPM:
Some notable ranks in Defensive RAPM:
Reminders: these are career RAPM numbers, so players with a different percentage of non-prime years will affect these rankings greatly. Players who are mid-prime now (no post-prime years yet) might be overrated, players who are missing prime years before 1997 might be underrated. This also treats the player as a single flat value over their career, so information on season to season changes (e.g. if a player is much better in prime, much worse in non-prime years) gets averaged out.
Some Random Observations:
-Jokic #1 makes some sense. Hyper-valuable player with strong peak, #1 in offense, somewhat surprisingly high defense, and no post-peak seasons to drag his average down.
-LeBron #2 also makes sense given how strong his impact is. GOAT-tier stuff from him considering how long he's been doing it. Offensively, he's just in the Top 5.
Offensive highlights:
-Curry 8th overall and 2nd offensively (just behind Jokic) is also pretty impressive, consistent with him being GOAT level offensively considering how many more non-peak years he has than Jokic.
-Chris Paul is 3rd overall and 7th offensively, continues to be loved by impact metrics.
-James Harden 4th offensively and 21st overall, solid.
-KAT at 6th offensively is a bit surprising.
-Durant 8th offensively but 16th overall, and Dirk just behind at 9th offensively and 17th overall.
-Nash at #14th offensively and #47th overall, seems a bit low compared to his reputation here.
Defensive highlights:
-Garnett's defense is #1, enough to boost him to #4 overall. Impact metrics alway love him, but seeing his defense that far above the crowd even with his non-prime years is a bit new for me. His offense is proportionally lower at #173, keeping him from looking best overall in this new stat.
-Old Mutombo is #2 defensively, with some separation after. I wonder if I've been underrating his defense.
-Caruso a bit surprising at #3 defensively, and Paul George at number 10 defensively... the top defenders are obviously dominated by big men, but a few perimeter players do sneak in. Andre Roberson, Tony Allen, and Iguodala are some of the other top perimeter defenders, though they're a tier down between #20–#30. Some of these players are lower-minute defensive specialists, but Paul George specifically is pretty high minutes player. I wonder if his defensive reputation compared to the other recent defensive wings underrates him.
-Draymond Green (5th overall, 5th defensively), continues to be loved by impact metrics.
-Duncan is 6th defensively and 9th overall. Great stuff. A bit below Garnett (as often is the case in impact metrics), but unlike some of the guys I mention below, both Garnett and Duncan don't seem to have their career value cratered that much by their post-prime years (note for DocMJ: Manu is 11th overall, so he's right behind Duncan, and supports your argument that he's underrated)
-Gobert, Ben Wallace, and old Robinson are all also in the top 15, as expected
-Some surprisingly lower ranks:
-Kawhi Leonard at #19 overall and #22 offensively is still pretty good, but a defensive rank of 173 is way lower than his reputation.
-Giannis Antetokounmpo at 38th overall is definitely lower than expected, particularly since his impact metrics in 19/20 were so good and we're also mid peak/prime for him too. Both his defense and offense are out of the top 50.
-Anthony Davis and Luka Doncic at 88th and 95th overall are also a bit low. Doncic's reputation of having worse plus/minus numbers continues.
-Dwyane Wade and Kobe Bryant are out of the top 100 overall. Wow! Kobe's 22nd offensively, right in line with some of the other Top 20 overall players, Wade's a bit worse at 42nd offensively. It's their defense that's disappointing... Wade's neutral and Kobe's a negative defender. One wonders how much non-prime years are lowering their ranking here. Kobe's reputation as having slightly worse impact metrics continues. For the Kobe fans: Kobe has an unusual number of non-prime games in his career (e.g. 266 RS games pre-age 22 when Wade was drafted, 325 RS games at age 32+ in 2011–2016, 50 + 22 PS games in those age ranges, for 663 total. For comparison, Wade has 0 games pre-age 22, 389 games after age 32+ in 2014–2019 RS, 45 PS games in those age ranges, for 434 total. Based on this, and considering their overall rank is right near each other, there is an argument that Kobe might end up looking better than Wade in say ~10 year prime RAPM, though neither are probably valuable enough in RAPM to crack the top tier based on how low their total career is).
Older players: These are the guys with a major portion of their career missing (pre-1997).
-Jordan 14th overall, and 12th offensively is GOAT-tier stuff, considering ~40% of his sample comes from his Wizards years at age 38–39, and there were nagging injuries in the 1998 regular season. His defense is 159, which is definitely isn't high, but at the same time it's right around the level of Marcus Smart, Jaren Jackson Jr., Kawhi, Jarrett Allen, so not exactly terrible.
-Shaq 13 overall is a touch town from the other modern bigs in Duncan/Garnett, but we're missing 93–96 which includes several prime years. His offense at #23 is strong but not quite as high as expected, but his defense is better than his reputation at 72.
-Old Stockton (12 overall) >> Old Malone (224 overall)
-Old Ewing and old Hakeem are disappointing, both out of the Top 400 overall (69th/70th defensively), at least compared to old Mutombo and Mourning and Barkley and Robinson.
Other Current players: these are some other guys for whom we only have young/prime seasons. We might expect their ranks to drop over time if they're mid-peak now and haven't had any post-prime seasons to drag them down.
-Tatum at 7th overall is obviously great, propped up by being Top 15 offensively
-Embiid 10th overall is also great. He seems much more valuable defensively.
