Been really strapped for time, so it's been hard to contribute.
My vote goes to Dirk Nowitzki - we've got a guy whose longevity + elite impact is exceptional (and IMO, could have gone a few places higher).
If we look at some RAPM splits, 06-11 Dirk was only 0.1 behind LeBron for #1 impact in the league, and he's got an elite impact footprint outside of this season too -
2002 PI - 4th (Duncan, Shaq and Stockton ahead, and T-Mac is waaay behind at 5th)
2003 PI - 3rd (Duncan, Garnett ahead, Shaq clearly behind in 4th, Stockton is well behind at 5th)
2004 PI - 4th (Duncan, Garnett, Shaq ahead, only Rasheed Wallace is really close to Dirk)
2005 PI - 6th (Duncan/Garnett/Shaq ahead, as well as Ginobili and Kidd)
2012 PI - 2nd (LeBron ahead)
2013 PI - 1st (!)
2014 PI - 5th (LeBron, CP3, Iggy and Curry ahead, and let's remember at this point, Dirk is 35, so this is still incredibly impressive)
In the larger splits, e.g. 2001-2015, Dirk ranks extremely highly too - the only higher minute players with a reasonable sample ranking ahead of him are LeBron, Duncan, Garnett and CP3. Dirk's impact is
elite.
As an offensive fulcrum, he repeatedly led elite offensive teams in Dallas with exceptional impact numbers.
He's an excellent playoff performer - his playoff +- numbers (and I'm generally rather sceptical of playoff +- numbers) weren't that flash earlier in his career, but it's worth mentioning that early career Dirk arguably didn't play on teams that maximised playoff impact and are more prone to fluctuations (i.e. all offence, mediocre defence teams). Dirk's impact looks much more pronounced later in his career, and part of it might be due to his post game, but I feel like a lot of it is that Dallas did the smart thing, and improved the fit around Dirk as an offensive fulcrum.
And really, looking at some of the series that Dallas lost... players such as Finley/Nash played well below their level (Nash having multiple series with TS% < 0.500 is pretty shocking for an ATG shooter such as himself), even against tough opposition, and I don't know just how much of that can really be pinned on Dirk's gravity as much as the team structure being less than ideal for playoff success. Couple this with the fact that Dirk was able to emulate (and arguably
improve) on his regular season numbers against teams with an average SRS of around 5.0 showcases some powerful playoff resilience to me.
I feel like the players beneath Dirk are either plain lower impact than him (e.g. Moses), or have worse longevity (CP3, Wade, Robinson). Robinson is probably the only player not voted in yet that I think has higher impact than Dirk (save for Walton, whose longevity is... shocking, or Mikan, who I really, really don't know where to rank, honestly). His combination of longevity and impact is exceptional.
I'd also like to throw in the idea that Dirk is one of the best close game players in history - from 2001 to 2015, Dirk averaged 28.5 clutch points per 36 minutes on 58.0 TS% (with excellent box score stats, e.g. lots of rebounds/extremely low turnovers). He
thrived in close game situations. But what's even more incredible is the plus minus numbers that Dallas accrued over this time.
Per 100 possessions -
2001: 4.3
2002: 19.9
2003: 17.0
2004: -9.6
2005: 22.4
2006: 16.7
2007: 30.7
2008: 15.8
2009: 17.4
2010: 30.5
2011: 38.4 (!)
2012: 3.9
2013: -1.2
2014: 24.9
2015: 30.3
In a 15 year sample, we've got 1 horrible year (2004, and that roster construction was... stupid) and 3 mediocre years (2001, 2012 and 2013). And it's worth considering that +- numbers are prone to quite a bit of fluctuation on a year to year basis. If we look at a 15 year sample, Dirk's career plus minus is around +17.9 per 100 possessions in clutch situations. That is...
remarkable. And even though Dallas was generally a good team during this time, +17.9 is
so good that despite the sheer fluctuation that a tiny, single season sample size provides, this +17.9 would have ranked 5th in 2017, 3rd in 2016, 4th in 2015 and so on. Dirk was a demon in close games, and his effect on Win Probability (factoring in scoring margin) from 2001 to 2015 is 4th, but in a fairly tight tier with Garnett, Duncan and Paul from 2-5 (LeBron is clearly 1st). He's almost a cheat code in this respect.
And what his close game excellence + playoff game excellence tells me is that despite his already gaudy, MVP-level impact, Dirk's impact numbers might actually
underrate how much he influences the probability of winning a game (and series) of basketball. He's got incredible resilience against tough opponents and scenarios, maintains these elite numbers on consistently good teams as the primary offensive option. I don't have a top 100 list or anything of my own, but I feel like Dirk would almost definitely go higher than #17 on my list.
Second vote goes to David Robinson - if we had impact numbers for Robinson's prime, he'd almost definitely rate above Dirk. I put Dirk above Robinson though, as Robinson appears to trend the other way in playoff resilience/clutch performance to Dirk, and his longevity is quite a bit worse. Absolutely unreal player though.

I don't think I'd honestly place Isiah in the top 30, let alone top 20, and this is somebody that acknowledges that he's one of the best playoff PGs of all time.
Those Detroit teams were pretty stacked, man. The current +- footprint of the 80s (i.e. ElGee's WOWY work) actually portrays Thomas as the 3rd highest impact guy on that team behind Rodman and Laimbeer. And that's not factoring in that there were clearly other guys, e.g. Dumars, who contributed quite a bit to winning. CP3's teams have had a few big names (Griffin, Jordan) and these guys are definitely good players - but they also had an utter fart brain of a coach in Doc Rivers, some
horrible bench support and the team chemistry assassin known as Jamal Crawford plaguing their teams.
Even looking at the playoff results for Detroit, their most successful run was the 1988-1990 period, where they won 11 series (and 2 titles), Detroit were clearly not winning on the basis of their offence - in the 60 games they played these 3 years, their average relative playoff ORTG was +2.9. That is... not a bad offence, by any means, but it's probably one of the worse playoff offences that actually won any championships, let alone two. And it's not like Thomas was doing it with
zero offensive help at all - Dumars was a good offensive player in his own right, Rodman's offensive rebound is projected to have a reasonable offensive impact, Laimbeer spaced the floor very well as a big (allowing guards like Thomas to actually penetrate to the rim and occupy the paint more than a paint-orientated center would) etc.
Even if one prescribes to the belief that LAC provided CP3 better offensive support than Thomas (and I don't think that's unreasonable at all, although I don't think the gap is quite as large as people would make out thanks to the negative presence of guys like Jamal Crawford on the team), CP3 actually averaged an ORTG of +4.9 in series in which the Clippers were eliminated the past 6 years. If you ignore the Spurs series of 2012 (where CP3 played poorly, no sugarcoating there), that improves to +6.4. Using team success as a barometer doesn't seem entirely fair here, because the gap in offensive support isn't as large as the general gap in ORTG, IMO. And in terms of defence, I can't vouch for Thomas all that much since he's before my time (and defensive statistics are spotty at best back then), but I don't hear all that much about Thomas really being a needle-mover on that end of the court, whereas CP3 is one of the best defensive PGs of all time.
This seems to imply that one of the biggest reasons behind their disparity in success is more so that the Pistons were a well oiled, very talented unit, and that the Clippers had a heap of structural issues despite having some big names on the squad. Couple that in with injuries (partially attributed to CP3) and an
incredibly hard conference (CP3 has only once played a team with under 51 wins in the playoffs... ever), and using team success as the metric of choice just seems to omit far too much information to me. After all, you mentioned looking at context... but also use team success as a barometer to state that Thomas is better, when team success is quite arguably
the metric most void of context when taken in its most raw form.
This isn't to say that Isiah was a bad player at all - he was definitely a good player. But he's one of the key examples of a player whose mythos is drawn from championships/playoff success as opposed to his actual play.
Generally, players who are primary offensive pieces on elite defensive squads (and therefore upper tier squads by Win/Loss) are often overrated through MVP voting. Guys like Iverson/Rose were obviously good players, but after-the-fact analysis showcased that this type of player is the most prominent exhibition where dissonance between impact and perception takes place. Now, if Thomas, as the primary offensive creator on an elite team (that won through defence) still only finished 88th all time in MVP shares, despite fitting this profile rather well, I'd hazard a guess that his modern day reputation stems more from winners bias, rather than having a remarkable intangible impact that stats just don't explain.
