It would be easier to understand what Jeebs was getting at if it was elaborated at all. Like which advanced stats does he not like, or which people are only looking at advanced stats without applying any context to them? It's not like we are seeing people just picking a pool of guys and said the one who leads X stat should be the winner simply because of that stat. And it's not like every advanced stat gives zero indication of on court performance just because someone feels differently about how much they should be used.. I mean the top 3 candidates in pretty much everyone's eyes are Joker, Embiid, Giannis in some order. The top 3 players in PER this year as an example are also Joker, Embiid, Giannis for this season. Those stats do, almost always, correlate to what the eye test shows as well. Very rarely do you have players who performed at a high level not rank out highly with advanced metrics and very rarely do you have players rank out highly in advanced metrics who didn't perform at a high level.
Do the analytics provide an avenue for people to make weird opinions on things, sure, just like watching games and just picking the player who takes/makes the most amount of difficult shots or highlight plays also clouds the eye test for some people too. But I would say most people who actually reference those numbers wouldn't waste their time doing so if they weren't also investing time in watching games as well. I know Ben from Thinking Basketball is pretty heavy in analytics himself but ties every stat he speaks on back to in-game action and shows how it happens in real time as well.
Even ignoring all advanced stats any of the 3 have a strong argument. Just in raw numbers I think Joker became the first player ever to drop a 2k/1k/500+ season. He put up 27/14/8 on the best efficiency of the 3. He has better on/off splits this season, and though both of the others finished 3 games ahead of Denver 6 of Denver's losses were without Joker, as far as that side of it goes when Joker is on the floor I think Denver ranks higher offensively and defensively than the Bucks or Philly either one (maybe not the Bucks offensively), nearly league last in both without him.
Plus had either Philly or the Bucks went on to win 60+ games I think we'd see almost nobody giving votes to Joker. But none of the top 3 played on some highly successful team this year. The whole "best player best team" thing has real merit, but the only guy that really applies to this season is basically a distant 4th to these 3. Like stated before it's only a 3 game difference. If you were to rank all teams by wins both Philly and Milwaukee are tied with Boston for 6th and Denver would be tied for 8th. It's not like we are comparing teams in 2nd to a team that wouldn't be top 10.
