What is, or who is, the best actual example of a "PF Jokic" in the modern NBA era?
To me, there are three interesting case studies:
a) Sabonis in Indiana, where he played PF alongside Myles Turner.
b) Nikola Jokic + Mason Plumlee lineups from 2018-2020.
c) Alperen Sengun + Steven Adams lineups from 2024-2026.
A and B fall a little short of the moniker because, although both guys have been compared to Jokic for obvious reasons, neither can shoot it like him.
Jokic played 1,223 minutes with Plumlee from 2018 to 2020. Basketball Reference lists Mason as the PF, but I think it's clear that Nikola was the more dynamic offensive player and therefore more of a power forward of the two on offense.
That obviously raises some questions about how we define positions. Is it determined by the style of play on offense, defense, or both? Usage/primacy? Does it really matter? I don't think so. Wemby is a center, and he's far more of an offensive focal point, creator, and dynamic offensive option than any of San Antonio's forwards. True for a lot of the great centers and their teams, like Olajuwon, Ewing, Robinson, Kareem, O'Neal, Yao, Wilt, etc.
Plumlee was and still is largely a Hartenstein-type center on offense: rim-running, rebounding, with some floater range and passing chops. So, I think the salient point is that Jokic was playing with a guy who largely fits the mold of a center on offense. So, he's "PF Jokic" here, at least on offense.
Here's how their individual stats were affected:

You can see that Nikola's TS% goes down, as does his rim FG% and frequency. That's to be expected when playing with a center whose game is limited to the paint. Taking more threes and being slightly more assisted. I think most of his TS% drop is due to three-point shooting variance. Short mid-range FG% down a little, which could be variance or due to more congestion inside.
Either way, it appears to be a relatively successful PF + C combination per the +/-, especially when we look at the lineup data:
Raw RS+PS lineup numbers, all leverage:
Jokic ON Plumlee OFF (7310 minutes): 115.8 ORtg (+5.2), 111.5 DRtg (+0.9), +4.3 NRtg
Plumlee ON Jokic OFF (3429 minutes): 109.9 ORtg (-0.7), 112.1 DRtg (+1.5), -2.2 NRtg
Jokic ON Plumlee ON (1223 minutes): 115.2 ORtg (+5.0), 108.7 DRtg (-1.6), +6.5 NRtg
Plumlee OFF Jokic OFF (1118 minutes): 107.7 ORtg (-2.5), 110.0 DRtg (-0.2), -2.3 NRtg
Raw, with only med/high leverage:
Jokic ON Plumlee OFF (6909 minutes): 116.0 ORtg (+5.1), 111.5 DRtg (+0.6), +4.5 NRtg
Plumlee ON Jokic OFF (3091 minutes): 109.5 ORtg (-1.3), 112.6 DRtg (+1.7), -3.1 NRtg
Jokic ON Plumlee ON (1192 minutes): 115.6 ORtg (+5.1), 108.4 DRtg (-2.1), +7.2 NRtg
Plumlee OFF Jokic OFF (765 minutes): 109.1 ORtg (-1.2), 110.4 DRtg (+0.1), -1.3 NRtg
All leverage, and adjusted for 100% offensive and defensive 3PT shooting luck:
Jokic ON Plumlee OFF (7310 minutes): 115.2 ORtg (+4.6), 111.7 DRtg (+1.1), +3.5 NRtg
Plumlee ON Jokic OFF (3429 minutes): 109.5 ORtg (-1.1), 112.3 DRtg (+1.7), -2.8 NRtg
Jokic ON Plumlee ON (1223 minutes): 113.8 ORtg (+3.6), 107.5 DRtg (-2.7), +6.3 NRtg
Plumlee OFF Jokic OFF (1118 minutes): 110.3 ORtg (+0.1), 110.9 DRtg (+0.7), -0.6 NRtg
Only med/high leverage, and adjusted for 100% offensive and defensive 3PT shooting luck:
Jokic ON Plumlee OFF (6909 minutes): 115.4 ORtg (+4.5), 111.8 DRtg (+0.9), +3.7 NRtg
Plumlee ON Jokic OFF (3091 minutes): 109.4 ORtg (-1.5), 113.1 DRtg (+2.2), -3.7 NRtg
Jokic ON Plumlee ON (1192 minutes): 114.4 ORtg (+3.9), 107.3 DRtg (-3.2), +7.1 NRtg
Plumlee OFF Jokic OFF (765 minutes): 111.3 ORtg (+1.0), 112.2 DRtg (+1.9), -1.0 NRtg
Although a small sample, the Jokic-Plumlee combination looks good with 3PT% luck adjustments and in the medium & high leverage minutes. The major benefit is on defense, but the key is that Nikola can keep the offense elite despite playing with another center who can't score outside the paint.
Digging deeper into the numbers, you'll see that rebounding is driving a lot of the net value here. Jokic + Plumlee had a 31.6 ORB% (+5.4), up from 28.3 (+2.4) with just Nikola and 27.7 (+1.6) with only Mason. 76.2 DRB% (+2.5) for Jokic + Plumlee, 75.6 (+1.6) for Jokic only, and 72.5 (-1.5) for Plumlee only.
Offensive TS% only drops from .573 (+1.3) with Jokic to .568 (+1.1) with the dual-big lineup. A clear example of Nikola's malleable offense, being able to largely maintain elite offensive production despite playing with another center. Defensive TS% drops from .568 (+0.8) to .533 (-2.3) going from solo Jokic to Jokic-Plumlee. Huge improvement in lowering opponent shooting percentages.
This was the 2018-2020 version of Jokic that hadn't quite reached the superhuman MVP production that he began displaying in 2020-21. He averaged 19.5 ppg, 10.4 rpg, 6.8 apg, 1.2 spg, 0.7 bpg, 3.0 topg, on .513 FG% (14.4 FGA/G), .340 3PT% (3.5 3PA/G), .568 2PT% (10.9 2PA/G), .554 EFG%, .829 FT% (4.2 FTA/G), .599 TS% (107 TS+) in the RS over this three-season stretch.
Those are realistic numbers for Cameron. Looks like a Sengun or Sabonis stat line somewhat. You'd hope that he shoots a little better from three and draws more fouls. But if he can make it work while playing a significant majority of his minutes at the forward position while on the floor with a big defensive center, that's huge. In a similar fashion to Jokic + Plumlee, you'd hope he allows you to maintain a high-level offense while reaping the benefits of a big, physical lineup. The two-way rebounding impact will be immense.
Boozer + Edey? Scary. Sengun + Adams has a 42.6 ORB% (+13.2) and 76.6 DRB% (+6.0) over 555 med/high leverage minutes between 2024 and 2026. I could see similar performance from Cam and Zach, given health and availability.
