1. LeBron James, 2016 (2009 > 2013 > 2012)You can argue many different seasons as LeBron’s peak and the overall goat peak. I have gone back forth between 2009, 2013, and 2016. In 2009 he is a force of nature and in just about every game the Cavs played he would come out of the gate in the first quarter and physically impose his will on the game on both sides of the ball. +15 on court with THAT roster is absurd. Had the greatest box score run in playoffs history. I think had Ben Wallace not gotten injured, 2009 would be remembered differently. In 2013 he plays a different role and without an injured Wade in the playoffs posts an absurd +30 rORtg. But 2016 does it for me. He posts an absurd +13.5 or +14 rORtg on court (depending on various methods of calculation) while shouldering massive defensive responsibilities, a +20 on/off, lifts a defense by more than +7 per 100 possessions (the territory of ATG defensive bigs) and then defeats a 73 win team posting a nearly +30 on/off in the finals.
One of the things that gives me pause of not voting 2009 LeBron as his peak other than just the sheer force of nature impact in
2009 was how inelastic his impact was despite who and who wasn’t on court. The supporting cast should not have been able to get this team to 66 wins and an 8+ SRS. One of the things that hurt was the injury to Big Ben who came back in the playoffs a shell of himself and was soon out of the league.

I’m pretty confident in James’s peak being the highest peak given the outlier nature of how many different seasons he has led in PI RAPM in whstever intervals of looking at surrounding years. Obviously, this doesn’t have to be the case, but I highly doubt that it’s not.

To say this ludicrous is an understatement. In the databall era, i.e., 1997-current, there have only been a handful of players who have led a season in RAPM multiple years and the longest span of years between leading in RAPM other than LeBron’s 14 is KG’s 4. LeBron was in 99th percentile in every season between 2007 and 2021 save 2019.

If you look at being in the 99th percentile rather than outright leading, then you get some longer spans such as Dirk’s 10 and KD’s 10. KD is interesting since he appears in the 99th percentile in 2013 and 2014 and then again in 2022 and 2023.
https://xrapm.com/table_pages/xRAPM_hist.htmlThe breadth of longevity and peak impact is quite extraordinary.
Cheema’s 5 year RAPM, 1997-2021https://www.thespax.com/nba/quantifying-the-nbas-greatest-five-year-peaks-since-1997/LeBron has the Highest 5 year RAPM in the 25 year dataset, 2 of the top 3 five year intervals, 3 of the top 4, 11 of the top 33.
LeBron has
ELEVEN different 5 year intervals in which he had the highest RAPM.
KG has 4,
Duncan has 2,
Steph Curry has 2.
11 is an absurd amount and is a technical outlier.

He is so very clearly the most valuable player of the 21th century is not even fun, and did it going from the late deadball era all the way to the small ball shoting era to boot
Simply being in the 99 percentile in 2007 and then in the 99 percentile in 2021 let alone leading in both years in a completely different environment is really beyond anything. If you look at the entire data set, all of these players I mentioned are outliers, but amongst just these players, LeBron is an outlier amongst outliers.
To match this 14 year band, someone like Jokić would have to be leading RAPM in a season in 2036.
If Jordan lead in 1988 then he would have to lead in 2002 to match the same span.
Over the past few years, for obvious reasons, the term "longevity" has been sometimes switched out for the phrase "just played a really long time" and it does a disservice to those players that can be impactful for such a long period of time let alone be the most impactful player over such a long period of time. Because the game changes in micro evolves, either your skill set has to evolve and/or your skill set is so dominant that regardless of era and environment you're still that impactful, e.g., Kareem.
2. Duncan, 2003 (>2002)Who was on this team creating this type of team? Duncan’s plus offense and GOAT level defense lifted a team to immense heights. I cannot think of very many scenarios in which this player wouldn't have the same results—1960s, 1970s, 1980s, 1990s, 2000s (proven), 2010s (proven), space and pace era, etc. Immense lift on both sides of the ball especially the playoffs. great regular and post season in which he shouldered a heavy load and didn’t falter. Impact metrics look great, especially in the playoffs. Defense is replicable in many different eras while his offense was continuously resilient throughout the playoffs. If we’re doing a “Veil of Ignorance” type simulation, I feel very comfortable with this version of Duncan being capable of providing championship impact.
Playoffs:
+3.8 rORtg on, -14.2 rORtg off (offense strong enough with him on, absolutely nothing with him off)
2. -9.7 rDRtg on, +8.9 rDRtg off (defense incredibly strong with him on, garbage with him off)
3. KG,2004We saw what happens when he's on a roster that has talent, and unfortunately, his best years were wasted by an incompetent organization, but the levels that he reached by being a positive in every single area of the game and dominant and some lead to one of the highest impact seasons in NBA history. I cannot think of any error that you put this player you put this player in and he doesn't contribute in the same way
4. Curry, 2016>2017>2015Changed the way people look at the game. 2017 was the better playoffs, but had uniquely favorable circumstances which makes me favor 2016.
Shaq 2000 would have been #3 here for me but it’s 2001-2025.
