This was a game in the short time period where Jordan was playing PG, and was before the Bulls used the triangle. And, while Pippen definitely wasn’t a primary ball-handler at that time, I note that Pippen went out very early in the game. The Bulls’ game plan here was very heliocentric, centered around getting the ball to Jordan and having him create.
So how much did Jordan create? Well, by my tally, in 86 offensive possessions, Jordan racked up 102 DTOs, and 60 EDTOs. Per 100 possessions that comes out to the following (my notes on this are in a spoiler at the bottom of this post):[/spoiler]
Great post and analysis. I also try to count his DTOs and EDTOs this game after seeing how much you got for him. And by my way of tracking like I did to every other player I do - I got MJ having 69DTOs and 34EDTOs - it really great.
First it's great to see more people get involved in tracking and checking film.
I will say, though, that is an unusually large disparity. Tsherkin had me checking his tracking possession by possession and we disagreed on one edto . When I looked over Lebronny's creations for a game from 2006 I counted 4 less edtos (39 vs 35). When we looked at a game from ewing in 90, i found 3 less. The biggest gap happened when Rubber dubber and elpollo tracked the same jordan game seeing a gap of 10.
But here we have a gap of 26. Might be worth checking the tape to see where the extra edtos are coming from. A possesion that stands out to me here is possession 2:2. Jordan drives and pulls 4 defenders and passes for what would be an open three, even with a 4v5 with Pippen injured. They win jump ball. Jordan draws two defenders and passes by two more defenders to give Grant a layup. 8 DTOs; 6 EDTOs.
I asked elpollo and he told me he got 6 dtos and 4 edtos. Looking at this closer...2. Jordan drives and pulls 4 defenders and passes for what would be an open three
Jordan does pull 4 defenders (and 3 extra ones). But does he take out all 4? Well one defender ends up guarding one of jordan's teammates. Is Jordan really the one taking him out here? I would say no as it would be wierd to just leave cartwright open. That said, on this matter elpollo ultimately sided with youelpollo wrote:When the drive in semi transition that have 4 defender around him right.
I counted it as 4 DTOs and 3 EDTOs
But I also could count as 2 EDTOs and 1 ADAs because it can be argue the that the 4th defender was on bill Cartwright at the post near Jordan drive
Where I think you lost both of us was this part.They win jump ball. Jordan draws two defenders and passes by two more defenders to give Grant a layup.
Laimbeer gives Grant space because he has to worry about Cartwright(and Jordan gets some credit for faking there) and still ends up challenging Grant's shot. That seems pretty weak for "renders a player unable to affect near or entirely single-handedly". Edwards is just rotating out to cover Jordan's teammate. And I think here we figure out where the gap comes from:elpollo wrote:I think our first possession before the jump ball are the same
But the difference is after jumpball
I think Jordan only pull 2 defender on him. 1 was in the paint 1 was defending Bill at Post and last one was rotating on number 54
The defender was already tight on Bill even before MJ move off to receive the pass.
I do think if you count players drawn by other attackers as "dtos" it would make sense you'd get higher counts there than most people doing it.
I think this all really goes to the high subjectivity of the exercise. I think my tally for this game was reasonable. At the same time, I think one could reasonably have a very different assessment using the same criteria (and I’m sure elpollo’s very different tally was reasonable too). You give some examples of differences. Those are plays that I think one could reasonably assess differently than I did. And the problem is that it comes down to an assessment of things like who a defender is being drawn to, whether a defender is really “out of the play,” etc. These are not even close to mechanical assessments, and in some cases even require knowledge we cannot possibly actually have (i.e. such as assessing who a defender is focused on—which, in plenty of cases, is something we’d need to literally be that person to really know for sure).
You often say that normal box stats like assists also are subjective, but there’s just way more guardrails cabining in whatever subjectivity is present there. There’s pretty clear criteria for what an assist is. You must make the pass before a shot is made. On its face, that is a clear bright line rule that is determinative in the vast majority of cases. So usually, absolutely everyone would come to the same conclusion about a given play. The only subjectivity is in the grey area where a pass is made and the receiver of the pass does a lot before scoring. People can differ in their tally in those marginal cases, but it’s still a pretty two-dimensional assessment. For most people, it’s basically just going to come down to how many dribbles the guy took before scoring. So there’s usually effectively zero subjectivity at all, and sometimes there’s basically a two-dimensional assessment that is pretty easy to be consistent with. The assessment of DTO/EDTOs is way more multi-faceted than that could ever be, and involves way more subjectivity and way more scope for inconsistency. It requires assessments of everyone’s positioning on the floor, a judgment of who defenders are paying attention to, an analysis of whether someone is “out of the play” or not, etc. It’s just a way more holistic exercise involving way more factors and way more judgment calls, which inherently makes it way more subjective. This is just definitely a way bigger problem here than it is for normal counting stats.
None of this of course refutes your main point here: that dtos/edtos(and adas) can scale up the more chances you are given to create. However, marking this as flaw for dtos/edtos as a "creation proxy" doesn't really follow. If a player is creating more in a role where they are set up to create more, you should still report that they are creating more, and thus far you haven't really offered a meaningful distinction between "was in a situation to dto/edto more" and "was in a situation to create more."
I think you’re not quite getting what my point is. There is a definite distinction between how much a player is creating in raw individual terms and what effect they’re having on how much their team is creating. The latter is what we should care about, but the former is what this analysis is geared towards.
If a player’s role is set up for them to create more, the flip side of that is that their teammates’ roles are set up to create less. A player in a more egalitarian system will create less but their teammates will be put in positions to create more. And the opposite is true in a more heliocentric system. What should matter most here is what effect a player is having in the context of the system/role they’re in. It will probably often be the case that the guy with more impact in this regard doesn’t actually have higher raw numbers.
For instance, to use a simplistic stylized example, let’s say Player A plays in a very heliocentric system, and Player B plays in a very egalitarian system. Player A gets 20 DTOs, and Player B gets 10 DTOs. Player A is the better creator, right? Well, not necessarily. What if the more heliocentric system means that Player A’s teammates can only be expected to get 5 DTOs, while the system on Player B’s team means that his teammates can be expected to get 16 DTOs? Suddenly, we’d expect Player A’s team to only have 25 DTOs and Player B’s team to have 26 DTOs. Player B’s team is better off (assuming DTOs are actually a good proxy in the first place, which is itself quite debatable, for reasons I’ve mentioned several posts above this). In that scenario, it’s likely that Player B is having better impact on creation, despite the lower number of individual DTOs (though it’s also possible that Player B’s team just has a system that creates more in general—which is another blind spot I’ve noted with your DTO/EDTO analysis). Or at least, Player B is able to raise their team to higher levels of creation within the teams’ chosen systems—which is the most important thing in a sport where the goal is to be the very best team. It may still be the case that if you took Player A and Player B off their teams, Player A’s team would have their creation fall off more—in fact, we may well expect that from taking away a player that the system is more focused on, since way more adjustment would be needed from the team when playing a system that was set up for a now-absent guy to create almost everything. But if Player B working within a more egalitarian system will get better overall team results than Player A working in a more heliocentric system, then their individual DTO/EDTO numbers aren’t really relevant. Player B is raising the ceiling of their team more, at least in this particular regard.
To be fair, this is an issue with assist stats too. But, as I mentioned in my earlier post, having done some of this analysis, I think the effect of system is bigger in terms of DTO/EDTOs than it is on assists. This is probably largely because of the outsized effect of plays with multiple DTOs/EDTOs, as well as the effect of counting stuff where someone decides not to even shoot (which both result in a scope for pretty exponential levels of tallies for the guy asked to do all the creation, even for single possessions, in a way that is outsized compared to the impact on those possessions). A guy asked to create everything while his teammates provide more static spacing will naturally just churn out numbers from that stuff to a larger degree than they’d churn out assists (and I think to an outsized degree compared to the actual impact they’re having—I wrote some about this several posts above as well). You have seen this yourself and have concluded that this must mean that assists are actually underestimating creation for heliocentric guys. But I think it’s really just that DTO/EDTO analysis is unduly biased in favor of heliocentrism—in other words, it is overcounting creation for those guys.
