The problem is that this isn’t really true.
- Ben Taylor’s playoff on/off data has Jordan at around a +23 playoff on/off per 48 minutes from 1988 to 1990. Which is obviously enormous. In the first-three-peat years, that goes down to about a +7.5 on/off (because the team does better with Jordan off the court than before). What do those numbers look like combined? Well, if we do weighted averages of the figures in those time periods, using the actual number of minutes on and off in each period and eyeballing the values in the charts in Ben’s video (for 1988-1990, I used -20 off and +3 on, while for 1991-1993 I used +1.5 off and +9 on), we get an overall average of about +6.41 on and -6.84 off, in the playoffs from 1988-1993. That’s a +13.25 on/off. Which looks great, but that’s also in per 48 minutes terms, not per 100 possessions. The weighted average of the Bulls’ pace in those playoffs is 90.06.
Which means that, using the Thinking Basketball on-off numbers, in the 6-year span from 1988-1993, Michael Jordan had a playoff on/off per 100 possessions of about +14.71! That certainly looks pretty GOAT-like!
- And then, Ben Taylor also provides similar data for the 1996 playoffs, with Jordan having about a +16 on/off per 48 minutes, which would translate to about +18.4 on/off per 100 possessions. And we know it was +23.6 in the 1997 playoffs and +13.1 in the 1998 playoffs. So, you’re right in the sense that the on-off numbers from 1988-1993 are not more impressive than those from 1996-1998, but it’s *all* super impressive.
If we combine those 1998-1993 numbers with the 1996-1998 numbers, we get a playoff on/off per 100 possessions of about +16.0! Which is enormous and obviously GOAT-like. Obviously, that’s missing some shorter playoff runs (i.e. his first three years and 1995), where we don’t have this data, but we have the most important years and they look incredibly good.
- I genuinely don’t understand the idea that Squared’s RAPM data suggests anything but great things about Jordan. Squared has RAPM for four different seasons for Jordan: 1984-1985, 1987-1988, 1990-1991, and 1995-1996. Jordan is ranked 1st in the NBA in 1987-1988, 1990-1991, and 1995-1996, and no one is even particularly close to him in any of those years. Meanwhile, 1984-1985 was Jordan’s rookie season, and he’s still ranked 6th in the NBA (and only behind three actual star players). While Squared’s data is obviously just a snippet, this is clearly quite supportive of Jordan as having been a dominant impact guy.
I didn’t say that Jordan’s impact data looks anything but great and is in the discussion for possible GOATdom.
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.

Also, it’s interesting to me because a while back, you were mentioning that the on/off numbers for someone like LeBron look so good because other players don’t touch the ball and then they don’t know what to do or are cold and haven’t felt the ball or something similar, but now you are using Jordan’s on/off numbers to show how good he was (which he was) but that wasn’t the argument about LeBron’s on/off numbers. Anyway:

Also, the partial RAPM looks very good for Jordan, but does not approach anything close to an outlier mythological peak that is above everyone else’s, which is what I was arguing. In fact, Magic Johnson looks every bit as good and maybe even peaks higher. Additionally, those who have been saying that Jordan’s defense in his younger/peak years was overrated have some data that possibly corroborates that:
DRAPM1985 Magic, +2.01; 1985 Jordan, -.13
1988 Magic, -.16: 1988 Jordan, -.05
1991 Magic, +.43: 1991 Jordan, +.61
Overall RAPM1985 Magic, +8.92; 1985 Jordan, +5.03
1988 Magic, +6.62; 1988 Jordan, +7.47
1991 Magic, +4.00; 1991 Jordan, +6.40
lessthanjake wrote:- The Moonbeam stuff is interesting, but it has some unsolvable problems with distinguishing impact when multiple good players didn’t miss many games. Given that Jordan, Pippen, and Grant missed very few games for many years, the model has virtually no way of distinguishing who had what impact between those guys in those years. And it has some pretty obvious issues with overestimating certain players (the BJ Armstrong Problem is one we’ve talked about in that thread, where his impact on the Bulls was clearly overestimated due to the minutes cutoff, which suppressed others’ impact; and there are plenty of other examples). In any event, until Jordan retired the first time (at which point the model quickly recognizes Jordan as super elite), it has basically no data to distinguish Jordan/Pippen/Grant’s impact, except for the 1986 Jordan injury season in some of those very early data points for Jordan. And, of course, even that injury-season signal is pretty iffy when we realize that Jordan had a steadily increasing minutes restriction and the Bulls got destroyed in the games where Jordan played but had super low minutes and those games end up counting against him for purposes of that signal. If the model even just only counted specific games where Jordan played the minutes cutoff (i.e. 18+ minutes), that signal would look way better, and Jordan would end up looking substantially higher in those early years (since that’s really the only signal for him that the model has and it’s clearly distorted). I should also note that a version of Moonbeam’s analysis (Lasso) has Jordan pretty immediately vaulting to the top range once that year is out of the system and staying there for a long time. Meanwhile, the aggregate of multiple WOWYR ratings—which is a version of the same sort of analysis as Moonbeam’s—has Jordan ranked above every single other serious GOAT candidate. Overall, I think it’d really flimsy analysis to decide that Jordan’s impact is not GOAT-like on the basis specifically of Moonbeam’s Ridge model—which is one piece of data amidst a sea of data going the other way, and it pretty clearly has inherent limitations that make it not all that suited to accurately measure Jordan’s impact in his peak years. And, frankly, I don’t even think Moonbeam would disagree with me.
Again, Jordan looks very good in Moonbeam’s set BUT his supposed peak (1991) does not match the mythological outlier status that’s so many have given it. Again, when the data about 1997 and 1998 and 1996 afterwords became available, people wondered what peak Jordan was like. We still don’t know completely impact wise, but the data suggests that he didn’t have the type of impact in these years as he did in his later years. Also, something tells me you would look at Moonbeam’s data much differently had the results been different, i.e., had Jordan coming out looking like the impact king.
Other players players look better than Jordan does. Russell for sure, though, as you have mentioned, there are fewer players in the league; Magic Johnson, which there really is no rebuttal to, even if you want to talk about the later years after he retires, but the years and in segments in which he played all the years look incredible; LeBron, especially in the LASSO data though this doesn’t matter much since we have confidence level RAPM data; curry looks comparable. If we had lineup data, maybe all of this would be sorted out differently but we don’t, but we DO have does not in any way suggest that Jordan’s suggested peak matches the narratives. It’s a great peak, but it doesn’t look like the unassailable, unquestioned GOAT peak at all.
Moonbeam’s RWOWY for Jordan (Jordan in the Ridge set, Jordan in the LASSO set)This was a cursory count, and others can do their own, but I took out every player who only played one year in the data segments, and I also took out every player who didn’t at least play solid rotational minutes for two of the years in the data segments. If it was close, I didn’t count the player; if somebody wants to go through and find players who played rotational minutes in every one of the years in the five year segments they can, but even if you did, Jordan would not look better than magic Johnson does, nor would he look better than Bill Russell does.
