Concerns for Kareem: 1. postseason sample size in 1977. 2. How much did his regular season "coasting" enable his 1977 postseason success?
The argument against Kareem would be that his ridiculously efficient scoring in the 1977 postseason was a hot shooting streak (hot even for him), which wouldn't be sustainable in a larger postseason or if he didn't coast as much in the regular season.
Question: since Kareem played in a different era without the three point line, did he face more drives toward/near the rim? That might not change the fact that Kareem had a better rate of quality rotations / stops, but it might shrink his volume advantage go successful stops. Also: Did Kareem make fewer stops or quality rotations in the second half of the 70s vs the first half?
First of all, I wanted to mention that I appreciate your metrics based approach to player evaluation and the discussions and insights you bring to this board.
Thanks so much! I'm glad to hear
homecourtloss wrote: Secondly, this is the second time I’ve seen you refer to player “coasting” in the regular season enabling a playoff run. Do you have some objective evidence for saying Kareem coasted in 1977 or LeBron in 2016 (other time you mentioned it)? How is coasting measured? How does coasting help with limited playoff sample sizes? How do we know “coasting” helped the playoff run?
I don’t see the argument for either “coasting.” LeBron was the Cavs’ defensive anchor in 2016 on a team that had few plus defenders; everyone knows about his post season defense but his regular season defense was phenomenal as well. How does a player “coast” and manage to do that?
What do I mean by "coasting"? There's a pattern some all-time players show as they get older. They have their best regular seasons (statistically, defensively, in terms of defense, etc.) when they're younger. When they get older, they get slightly worse by these metrics in the regular season. Yet in the playoffs, they show greater improvements vs their regular season selves, and sometimes even improve over their younger playoff selves. There's evidence that this happened with older Kareem, older LeBron, older Jordan (though I don't think his 2nd threepeat playoff improvements are enough to take 98 Jordan over 91), Shaq (e.g. 2001), Kawhi, Curry (e.g. 2022), etc.
What causes this? There's a few possiblilities. For example,
1. Players have a higher motor when they're younger. This motor declines as they get older. This decline most often shows up in worse defensive performances (or less consistent defensive effort) relative to their younger selves, at least in the regular season. 2. Certainly as players get older, they gain experience and versatility which allows them to improve more. 3. Players may even intentionally decide not to go 100% in the regular season as they get older, to decrease injury risk, limit wear and tear, improve longevity, and save up their motor to reach that higher gear in the playoffs.
Evidence in support of coasting: Both Kareem and LeBron had media articles and stories about their declining defensive effort in the regular season as they got older. There's also statistical evidence...
Ai. 2016 LeBron (regular season -> playoffs): +1.6 in AuPM, +3.5 in Backpicks BPM, improvements in Basketball Reference's BPM, improvements in WS/48, and I believe improved in RAPM/PIPM. These are noticeable improvements in almost all metrics. 2016 LeBron's regular season was below his earlier regular season performances in most of these metrics (compared to 2009, 2012, 2013), but his 2016 playoffs >> 2016 regular season, and his 2016 playoffs may be > 2009/2012/2013 playoffs. Aii. 2016 Cavs (regular season -> playoffs):
+6.93 offensive rating improvement, 1.92 defensive rating improvement, and
+5.84 SRS improvement (5th all time) . So the improvements from the regular season to the playoffs by LeBron (and possibly others) does make a difference in team performance. (source: Sansterre's Top 100 Teams)
B. 1977 Kareem (regular season -> playoffs): significantly improved in Backpicks BPM, Basketball Reference's BPM, WS/48, etc. Again, 1977 Kareem's regular season was below some of his earlier regular seasons in these metrics, but his 1977 playoffs is clearly his best.
Why does this matter? Well, it becomes a question of each player's value, and what we value in our GOAT peaks. If 2016 LeBron and 1977 Kareem performed at their playoff level throughout the entire regular season (and if the metics showed this), I think we'd be almost universally taking those seasons as their peaks... and those peaks would have greater arguments against their peers. But they didn't... so instead we're debating 2016 vs 2009/2012/2013, and we're debating 1977 vs 1974/1971 (and vs 2000 Shaq).
That doesn't mean 2016 LeBron or 1977 Kareem had bad regular seasons. Like you say, Kareem still squeezed out 53 wins from a sub-optimal roster and 2016 LeBron was still his team's best defensive player. But they were worse relative to the heights they reached in the same playoffs, and in earlier regular seasons. Worse regular season performances do decrease value (even if you really don't value the regular season, a worse regular season performance -> likely a lower seed -> harder playoff route -> thus lower championship odds).
So,
Question 1 is: how much worse were these players in the regular season, and how much value does this take away from them? Question 2 is: does this regular season coasting enable their playoff improvements, and does that matter? There's an argument that much of the improvement comes from their improved experience. But you could also argue that, as these players get older and their motor wanes, they actually need to coast a bit to enable these higher-motor, higher-value, lofty playoff performances. If this is the case, then if these players were to try more in the regular season to limit their regular season disadvantage (e.g. if Lebron were to limit his 2016 regular season disadvantage vs 2009 or 2013, or if 77 Kareem were to limit his disadvantage vs 1974/1971 Kareem or 2000 Shaq), then they'd be losing the energy/motor to perform well in the playoffs and thus limit the advantage they have in the post season.
Thank you for your thoughtful answer. I wanted to concentrate on the two bolded portions and when I have time to Kareem’s section.
In the first Bolded, you mention about motor and younger players with a greater motor, and while someone like 2009 had an incredible motor, 2016 regular season LeBron had one of the most impressive regular season defensive synergy numbers by any player let alone a primary offense creator over the age of 30. If he were coasting, how would he generate these insane numbers?

This was LeBron at 31 and approaching 50,000 minutes. He was charged with being his team’s entire defensive system in addition to being the best scorer, creator, and often times, rim protector.

No data available for transition defense, defense on cuts, and defense on offensive rebound out backs.
In his thirteenth season playing on a team that's otherwise not that good defensively, James quietly out together a great, great defensive season because he had to since his team really had maybe three other plus defenders. Unlike Kawhi and Draymond who were subpar in some categories, James was at worst in the 73rd percentile.The argument, “well, LeBron didn’t match up against the opposition’s best scorers doesn’t really hold water because look at the overall FG% of Dray’s, Kawhi’s, and LeBron’s opposition.

In the second bolded, I see what you’re saying but how do we know a suppposed coasting led to over-performance in the playoffs. David Griffin talk to little bit about the 2016 team in mentioned how they were not able to play the way they could in the playoffs because they didn’t have the defensive personnel to play at full throttle every game. Now, it could be said that well LeBron is part of that now playing the full throttle but when you look at his synergy stats, they show that he was going hard. That team was built specifically for the playoffs as Griffin mentioned knowing that a day off between every game at least allows them to gear up for an all out effort each game. I find it very difficult to believe that that bump in the 2016 playoffs had anything to do with any supposed coasting.
