Very important point. But I think we must be aware that this makes us enter philosophical terrain. Because what you're saying, in essence, is that it is Smart's offensive ability (being a capable PG) that allows his team to have an oversized and switch-heavy built in the first place. That makes him the nucleus of that team's defense. I think that's fair to consider.
However, is that really fundamentally different from looking at other players' offensive games and assess defensive value based on that? An offensive star player may play in such a way that minimizes turnover risk and maximizes offensive efficiency of the team, which in turn has positive effects on the defensive side. Another offensive star player may allow for a team construction or line-ups that are defensive-oriented without losing (too) much on offense.
The former I've heard in debates about Dirk Nowitzki. The latter is something that is at times brought up with Curry (allowing GSW to play with two defense-first players that do not space the floor, like Looney, Green and to some extent GPII) but could also be brought up for heliocentric approaches like Luka this year, or Harden and LeBron in the past, where one offensive engine allows the team to be built around offensively limited players that can fully exert themselves on defense.
I assume most of us would feel uncomfortable having any of the aforementioned players (besides prime LeBron) anywhere near a DPOY discussion, even if we can acknowledge their impact on roster construction and the defensive focus of role players that allowed them to have some really good defenses at some point in time.
So the question then becomes: how does the Smart situation fit into this debate, which is very different but – at the same time – similarly looks at the offensive qualities of the player in question to assess defensive impact at the team level? Or does the fact that Smart's own defensive ability is still key in this context render this a situation that is per se not comparable to the others?
But that would feel mostly like a philosophical choice around the spirit of the award, because the impact is there for the other players as well – and we'll have to decide how to deal with that. This seems rather unproblematic for POY debates where impact can be analyzed holistically, but I find it to be much more problematic when it has to be broken down to defensive and offensive splits.
i would look at it from a different angle
when a player does somethingh in offense that allows his team to be better in defense, like low turnovers, that is part of his defensive impact
when a player does somethingh in offense that allows his team to play more defensive lineups without losing much on offense, that is his -offensive- impact in the way of versatility
putting actual examples
smart doesnt do anythingh in offense than the average point guard wouldnt do as far as helping the defense, he is not out there with a historically great turnover profile (chris paul) or somethingh like that, is not what he does in offense that helps celtics defense
what he does, is being more switchable than other point guards AND being a much better defender than the average point guard
an argument for smart as dpoy would argue that he "takes away" more points off the opposite offense over the average point guard, than even the best centers "take away" over the average center
someone like curry is the opposite, is not that he makes warriors defense better, is that his offense is versatile enough he can play with non shooters like dray and looney and still have his impact so warriors can play defensive lineups with a couple non shooters and know curry will still be impactful
So, you're getting at something really important:
The fact that a guy's "on-court offensive impact" can be influenced by his defensive capacity and vice versa.
I find it tricky to have a definitive answer to how to reckon with this discrepancy, and it's why I always emphasize above all to focus on a player's overall numbers as the north star rather than offense or defense, because if you do the opposite, you have a tendency to bias your overall assessment.
The example I've seen a fair amount this season is the idea that Steph Curry is an offensive star so we should dismiss the fact that he has the best on-court DRtg in the league among all big minute players as noise, and express disappointment that the team's ORtg isn't better with him on the court, completely ignoring the fact that his overall numbers have generally been well ahead of any teammates.
So yeah, if you want to "re-allocate" apparent defensive impact to the offensive side of the court in such cases, that makes sense to me, or if you want to take the DRtg literally that makes sense to me too, but whatever approach you use, you have to make sure you're not taking half the data as real and the other half as noise or else you'll end up with a biased result.
