Why do you think those shooters had good games? It's literally in Lebron's game to primarily be a playmaker. Durant can't touch Lebron in terms of passing, he is primarily a scorer.
Durant had 30/6/2 on 548/394/839 shooting while Lebron had 28/10/7
I suggest you look at the playoff resume's of James, Leonard and Durant. Other than casual fan stats like ppg Durant is distinctly behind James and Leonard in terms of playoff impact historically across the various advanced stats.
1. James
2. Leonard
3. Durant
That's the order if you're ranking their postseason numbers + advanced stats+ability to turn it up compared to regular season. James and Leonard are in a class separate to that of Durant when it comes to this stuff. If you actually knew the numbers then you'd know that prior to joining GS, Durant continuously experienced Harden-esque playoff failures.
Which year did OKC choke besides 2016?
2011: They make it to the WCF before getting Swept by a determined and incredible Mavs team. KD puts up 28.5/8/3 on solid shooting with Harden being a Nothing player at the time and Westbrook being a fringe all star level guy
2012 they were the under dog with Bron+Wade > KD+Westbrook
Durant had a amazing playoffs with him average 28.5/7/4 on 52% shooting. Harden and Westbrook play terrible in the finals and the Thunder fall to a deeper Heat team led by Lebron
2013: Westbrook gets injured early on and KD with little support falls in 5 to the Grizzlies. Perhaps he could have shot better but still playing as the primary option against a great defensive team in the Grizzlies he still poured points in. Jusy had little support. Similar to 2005-2010 Lebron where he put great numbers but had poor shooting and unclutch moments. Puts 31/9/6 on 45.5% from the field
2014: KD wins reg season MVP. Goes out and plays crazy good to get the Thunder to ECF. They miss Ibaka first two games and end up falling in 6. He loses to the spurs in 6 while Lebron ends up going home in 5 in the finals. He got criticized for missing a clutch game tying 3 I believe this year. Averages 30/9/4 on 46% from the field which is insane performance overall
2015: KDs legacy is impacted by injuries like this post year. The Weat was weak and the Warriors were beatable this year with the Cavs and the east being really soft. He misses the entire playoffs and 55 games in reg season with major foot injury. Loses his best chance at a ring with the Thunder
2016: Final year there. This year he no doubt choked vs the Warriors as despite great statline getting 28/7/3 he shot terrible overall at 43% which was mostly due to disappearing in game 6 and 7.
His 2013, 2014 and 2016 performances are very similar to Lebrons 2008 and 2010, 2011 performances with both players failing to step up and deliver in clutch moments
Kawhi is an elite player but Playoff wise he is behind KD. KD has lost 2 years (2015, 2020) in which he would have been a final 4 team at the minimum if he had been healthy.
Lebron started winning once he got players to support him. Wade for the first two years was a top 7 player and the last two still a top 20 who could deliver in clutch moments. He had Bosha top 10 PF), Allen, Battier, Miller as great supporting shooters who helped make sure he couldnt he closed down and prevented from scoring with efficiency like we saw from 2008-2011.
KD saw the exact same happen to him when he joined the Warriors.
2017-2019 Curry was a consistent top 5 player
2017-2019 Klay was a consistent top 7 SG
KD did have another supporting star player but Draymond was mostly there for defense and leadership rather than offensive and spacing contributions.
KD has never been dominated in a final series by Lebron. If they meet this year in the finals we will see who is better with both having elite teams though the Nets being idiots and getting an offensive hog in Harden hurts their chances of winning
