I said that the idea that his peak of 1991 and the surrounding years is some type of outlier mythological monster isn’t supported by any of the data at all. Everything you just listed is very nice and good, but it’s type of data that other players have done similarly or in the case of someone like LeBron, even better since we have RAPM numbers.

But that chart is just taking the absolute best +/- periods for other players over relatively short timespans in a low-sample-size measure. Jordan’s best playoff on-off years aren’t all distributed next to each other. When you go to larger sample sizes—which is obviously an important and superior thing to do with playoff on/off data since it’s all low sample size in general and we want to look at as large a sample as we can—we see that in the data we have over 9 playoffs, Jordan has about a +16.0 on-off per 100 possessions overall. For reference, the best 9-playoff span LeBron has in playoff on-off is +13.9, and it was +10.4 in his prime years (defining 2009-2020 as his prime) and +10.2 for his career. Of course, we don’t have *all* the years for Jordan, so we can’t make a full comparison, but it certainly looks
very GOAT-like for Jordan when we actually properly look at all the data we have.[/quote]
Again, Jordan looks good but nothing outlier or anything that seems to show consensus GOAT peak. Also, not sure if you’re trying to apply BKREF’s pace estimates to eyeball estimates of a graph or not here. Pace probably does favor 1990 Jordan compared to 2017 Lebron for single, but we have surety of LeBron’s numbers while it’s fuzzy for Jordan’s. I’m assuming you’re using DraymondGold’s numbers, which uses some average which we discussed but since it’s being used:
Jordan's best 1-year average: +33.5 or 33.75 (1990; +24 in 1989)
Jordan's best 2-year average: +28.7 (1989-1990)
Jordan's best 3-year average: +23.4 (1989-1991)
Jordan's best 4-year average: +20.2 (1988-1991)
Jordan's best 5-year average: +18.5 (1989-1993)
Jordan's best 6-year average: +14.4 (1988-1993)
Then, he discounts 1995:
Jordan's best 7-year average:
+16.6 (1989-1997 discounting 1995 which has greater uncertainty;
it's +12.3 to +12.9 ish if we include 1995)
Jordan's best 8-year average:
+16.0 (1989-1998 discounting 1995 which has greater uncertainty;
it's +13.6 to +14.2 ish if we include 1995)
Jordan's best 9-year average:
+15.2 (1988-1998 discounting 1995 which has greater uncertainty;
it's +13.5 to +13.9 ish if we include 1995)I’m not sure whether he is counting 1995 in an existing range or instead of a border year on that range. I recall he said there is no 10-year number when literally speaking there should be one, so either he skipped the 7-year average or he skipped the 10 year average.
Lebron’s 2017 postseason on/off per 48 minutes is +33.4
Lebron’s 2016/17 postseason (2-year) on/off per 48 minutes is +24.9, and he also has a smaller sample stretch of +25.8 in 2007/08.
Lebron’s 2007-10 postseason (4-year) on/off per 48 minutes is +21
Lebron’s 2015-21 postseason (6-year) on/off per 48 minutes is +16, and his 2007-12 stretch is +15.4
Lebron’s 2014-21 postseason (7-year) on/off per 48 minutes is +14.9
Lebron’s 2012-20 postseason (8-year) on/off per 48 minutes is +13.1
Lebron’s 2012-21 postseason (9-year) on/off per 48 minutes is +14.4
Lebron’s 2007-21 postseason (14-year) on/off per 48 minutes is +13.8.
Lebron’s 9-average is better than Jordan’s best 6-year average, and his 14-year average is close to that 6-year average. Nothing stands out here really.
