The video is a perfect representation of why the discussion is so stupid.
The only area of basketball that modern players are unarguably better/greater at than previous eras is shooting, and even then it's much favored by the rules that enable offensive shooters with so much space (no illegal defense), freedom of moving/dribbling, hesi-moves to generate separation, etc etc etc.
A game of teams across eras would be entirely defined by the ruleset applied. Sure, Curry can out-shoot the Jordan Bulls or the Bird Celtics... But what is he gonna do if he's called for dribbling and traveling violations on every single play? It would be impossible to adjust on the fly, you'd need extensive time training under the "old rules" to naturally play that way during a compe ive game.
Having said that, the hypothetical scenarios are fun to muse around. Would love to see Shaq with 4 shooters spacing him out tbh.
