1. 2017 KawhiThis is an excellent regular season with a monster playoffs where he showed that his playoff resilience didn't even care about facing the greatest roster ever, only to be taken out on one of the more famous cheap shots in recent memory. A full WCF would make people like this season more and I can't blame him for a cheap shot injury. 2017 Kawhi wins on lots of teams that had guys who will be listed above him here:
Kawhi's 31.5 PER is 13th all time based on 100 MP and 8th all time for multi-series playoffs. His WS/48 of .314 is 9th all time based on 100 MP and 6th all time for multi-series playoffs. And that's with 1954 mikan included above him. Even with very generous 100 MP and 20 PPG limits, his TS% of 67.2% is 24th all-time. For 200 MP and 24 PPG, it jumps to 6th, and one of the people ahead of him is himself.
If this was a one year phenomenom, I might understand the hesitancy. But "Kawhi puts up huge playoff performance" is not a one year phenomenom. If we are truly talking about peaks, there aren't many higher than 2017 playoffs Kawhi.
2. 1983 Moses MaloneFo' Fo' Fo'. Led the league in regular season PER and WS48 while putting up 24.5 ppg and 15.3 rpg and winning MVP. Then led the playoffs in PER (25.7) and WS48 (0.260) while putting up 26 ppg and 15.8 rpg on 58.7 TS%. In the Finals, he demolished (35 year old) Kareem with 25.8 ppg and 18.0 rpg in a sweep. I was actually just looking at this season to see where I might put it and then convinced myself when I looked at the rest of the Sixers in the playoffs. After Moses at 25.7 PER and 0.260 WS48, the next highest was Maurice Cheeks at 17.3 PER and Bobby Jones at 0.164 WS48 (Dr J really fell off in the playoffs). That puts Moses as far and away the best player in arguably the most dominant playoff run ever. One that he called before it happened just to make it more impressive. This isn't Shaq with Kobe or KD/Steph all having each other's backs in dominant 1-loss runs. Here are 6 dominant title runs I could think of off the top of my head and the separation between the #1 and #2 player on those teams, sorted by WS48 differential:

We can see that for the 2001 Lakers, 2017 Warriors, and 1999 Spurs, the #1 and #2 were practically identical. Except for BPM, Moses ends up there with MJ as being easily the best player on his team. And for what it's worth, BPM had Moses as the 4th best Sixer in the regular season, almost 3 behind the team leader, so that shows how much more it liked him in the postseason that he led the team. This may have been a guy who joined a stacked team, but it ended up a one man wrecking crew.
Moses gets disrespected enough on all-time lists, a 3-time MVP with a side hustle of smacking Kareem around in the playoffs shouldn't get the same on peak lists.
3. 2006 Dwyane Wade (alternate 2009 Wade)
I'm a floor raising kind of guy I guess, which doesn't seem typical on this board. People who have everything put on them and come up big in the biggest moments with little to no margin of error impress me more than ceiling raisers putting the finishing touches on an already great team. It just seems like a more common problem to solve throughout NBA history than what to do with all this extra talent. Wade had a very good 27/7/6 regular season as a 3rd year player but obviously this is about the playoffs. On one of the jankiest looking title rosters you'll ever see, on a team where Antoine Walker played the 2nd most playoff minutes and White Chocolate played the 4th most, and Shaq was often getting outplayed by Zo, Wade saved his best moments for the biggest series.
Shot 61.7% in the ECF (68.4 TS%!!) against a still very good Detroit team that had just held Lebron to 81 ppg in the previous series. 26.7/5.5/5.2 looks even better when you realize the pace was 83.8. And then of course there are the Finals. Did he shoot 2 to 3 to 40 more free throws than he should have? Sure, but free throw totals were pretty elevated that year so his totals are only sort of absurd. Put up 34.7 ppg, 7.8 rpg, and 2.7 spg on 57.2 TS% while maybe leading the best overall Finals comeback ever. Weirdly, the only team that has probably come closer to losing the Finals before winning is also a team with Wade in the 2013 Finals (with 3rd probably also including Wade in the 2011 Finals). The Heat were down 2-0 and down 13 in the 4th quarter of Game 3. That's dangerously close to "1, 2, 3 Cancun!" time and instead Wade just went crazy and put up 42, 36, 43, and 36 in the next 4 games. In a series with a pace of 90! With 3 of the games decided by 1, 2, and 3. In other words, turn those 42/43 games into just 39 point games and the Mavs are celebrating. Efficiency may not be crazy but on that volume with such a weird, offensively limited roster around him against a very solid defense, this is perhaps the best Finals performance ever by anybody not named Lebron or Jordan. It's a title snatched out of thin air that very few players can say they would have been able to pull off. This is a peaks project and it's hard to peak much higher.
Questions about 2021 GiannisSince 2021 Giannis seems likely to be big in this thread. Are people really convinced this was much better than 2019 or 2020? It seems like the only difference is that Giannis injured Kyrie to get past the Nets, similar to Zaza with Kawhi, otherwise Bud was going to be fired and it would be another summer of questions for Giannis. I didn't expect him to beat the full power Nets, that's not fair, but after Harden got hurt, I don't think it would be crazy to expect that Bucks team to be better than the Nets. Plenty of people thought it would be a good series before Harden got hurt and given that the Nets were 33-8 with Harden and 19-17 without, it's not unreasonable for Giannis to be expected to win. And yet they looked awful in games 1 and 2 and then game 4 was close when Kyrie was taken out. And even then, a hobbled Harden came back and was enough to win game 5, even guarding Giannis on the biggest possession, and then the Bucks needed every last bit of game 7 to beat a very injured Nets team. Before moving on to a weak Hawks team and a Suns team that only faced injured opponents in all 3 rounds. If anything, it feels like 2022 Giannis was the most unstoppable version of him. The Celtics had to build a crazy amount of walls to stop Giannis, even with no Middleton around and who know what happens in game 7 if his teammates aren't historically awful from 3.
Questions about 1976 Dr JIs there any reason to be so high on Dr J compared to Moses? Moses won 3 NBA MVP's. Maybe voting was worse than it is today, but 3 bad votes? 2 in a row in a league with Bird, Magic, Kareem, and Dr J? Getting a 40 win team to the Finals? Taking over Dr J's own team and getting him his title? Feels like people are discounting Moses too much. I would get if 1977 Dr J dominated the NBA right away, but he fell off quite a bit, though he did recover in 1980-82.
