I think superstars who excel at creating for others as well as themselves will always have a leg up on great individual scorers like Tatum. Next after that would be guys who are elite scorers and also change the game defensively, e.g. Embiid or Kawhi.
For young(ish) playmakers I would list Doncic, Giannis, Jokic, to name a few.
But Tatum has clearly shown he can be in that top tier or on the verge of it. If you have the right team around him and you get a lucky playoff draw, team gets hot, etc, that could be enough for a title run.
