Players who were about as good as Nikola Jokic at about the same age (within a year) or younger, according to BPM:
LeBron: +9.3, ~10 months younger
Magic: +9.2, ~6 months younger
Paul: +9.2, ~9 months older
LeBron: +8.3, ~22 months younger
Magic: +8.3, ~6 months older
Jordan: +8.2, same age
Barkley: +7.9, ~12 months older
Antetokounmpo: +7.6, ~2 months older
LeBron: +7.4, ~2 months older
Davis: +7.1, ~1 month younger
BPM taken by itself can be dodgy, of course, but other mainstream stats also support the idea that he's a future MVP. He ranked 4th in the RAPM posted by shadow a few days ago, 9th in WS/48, 6th in RPM, and 6th in BPM. The only other players who rank in the top 10 across these stats are Curry, Paul, and Leonard (LeBron and Durant are near misses, ranking 11th in WS/48 and 11th in RPM respectively). These, of course, are all elite players currently in their primes, while Jokic just recently turned 22.
Davis, Antetokounmpo, and Towns, in contrast, occasionally appear in the top 10 of boxscore-only stats, but rank just 17th/18th/51st in RPM (which includes some +/- information) and 35th/72nd/149th in RAPM (+/- information only). Davis of course is a couple years older than the rest of these guys to boot.
I would argue that the main reason he's not talked about more is that he doesn't "look" like an MVP to a lot of people. Personally, I fell for this trap a few years ago with Curry. He wasn't an above-the-rim finisher, and he was a mediocre passer for his position, both of which I took to be huge red flags that put a ceiling on his potential. In retrospect of course this is silly, and a look at the list of MVP winners shows why: MVPs are all amazingly different from one another! Almost every new MVP is a breed of his own, completely unlike any previous MVP. With that in mind, I see no reason to hedge on Jokic; he has as good a shot as anyone at being MVP in 2020.
