The NBA has absolutely changed. Namely, the PG position has been completely redefined. They used to be pass first guys who were great leaders and had great handles and great vision in traffic. Now they are guys like James Harden and Russell Westbrook. I mean c'mon. Those guys aren't PGs. Chris Paul, Ben Simmons, and Rondo might be the only true PGs left. (And I can't stand Rondo).The league has changed in very significant ways since the days of Magic, Isiah, Billups or even Nash. Historical facts such as these have little relevance to today's game IMO.
However I do disagree with you that the facts aren't still relevant to today's game (small sample size that it is). Chris Paul has been The Man at PG for over a decade. And what has he gotten for being an ALL WORLD defender, great facilitator, and excellent scorer? Absolutely nothing. He wins you regular season games and solidifies an offense. What he can't get you is playoff championships. And that's in THIS era.
I'll predict a bit and suggest that Ben Simmons won't win anything barring someone on his team becoming a superstar. Like Paul, he'll win you regular season games, but he almost offers nothing in the postseason (and will somebody PLEASE teach that man to shoot!!!) He'll be plagued with early playoff exits his entire career. (That all goes out the window if Lebron shows up on his doorstep).
Rondo, the absolute mess that he was, used to ALSO win you regular season games and stabilize an Offense. But he couldn't win you post season championships (And no one should dare bring up Boston's championships. That dude road 3 HOF's coat tails all the way to victory. Elliot Perry could have won with those 3).
My point is that history isn't kind in it's projections for Trae Young and championships. He'll have to be next to some amazing players who can take over a game in the playoffs. He will HAVE to be next to a SG who can defend. And he'll have to more than likely be the 2nd or even 3rd best player on his team. If Chris Paul couldn't do it with one or two "stars", Trae Young sure as heck can't.
