If playoff Ant showed up in the regular season this year he'd probably get an MVP. He just hasn't put it together in the regular season. That's the only thing that is separating him from the best of the best.
I think there's like 6 guys that are on a similar level, (Ant being among them), after the top 3 of Jokic, Luka, and Giannis. Embiid, SGA, and Tatum are at the top of those players, but I can't separate Embiid from that pack because I don't trust him to stay healthy over the course of a regular season and long playoff run. SGA is the most likely to separate himself, but he just hasn't had the playoff success yet.
