As an aside, the modern evolution of the big man has been amazing.
You can argue small ball expedited it, since the simple explanation for that play style was to mazimize spacing for your best player vs advanced defenses (i.e. LeBron) yet big men of that era weren't skilled enough shooters for defenses to honor.. hence the downsizing strategy with forwards (i.e. Battier) at the 4 and 5. This of course became a trade off with compromised rebounding and post-defense.
But once bigs started to level up (i.e. Brook Lopez, Marc Gasol, etc) all of a sudden the end goal of small ball could be accomplished without the compromise.
To your point, there was a concurrent evolution where heliocentric ball (i.e. Bron-ball, Harden-ball, CP3-ball, Luka-ball, etc)... having your best player apply constant pressure on defenses with scoring and facilitating... was typically perimeter oriented. Downside is this would often turn dexterous big men (i.e. Bosh, Love, Ayton, etc) into basic bytch spotup shooters or rim rollers. Not really maximizing any other abilities.
But once again big men have leveled up (i.e. Jokic, Giannis, Zion, etc) where they can assume the role of heliocentric ball as needed but can also switch back to off-ball and conventional play as well (PnR, post-ups, etc). Such bigs are more versatile bc they naturally have other skills for off ball, whereas guards struggle with what to do if they aren't dribbling air out the ball.
