An opinion from an old basketball watcher: I believe that the game just changed significantly.
We used to play basketball with a sort-of "hands-off" policy. That is now completely gone.
The "Old Way" to play emphasized clever ways to mask physical contact (in the paint rebounding or taking charges which used to be obvious), and now the cleverness is still demanded, but in entirely different ways.
New basketball, at least in the NBA, is frankly more like the football I played in so-called "touch" football in college intramural. We allegedly were not allowed to do certain things, but that was a joke, right up to drawing blood. Blood drawing did not necessarily mean a foul. Back to basketball, the game now is just put your head down and blast in there, usually getting to the foul line ... or it's banging the body --- MAJOR Banging --- of any guy trying to more slowly back you down. Cleverness still counts, but it must be cleverness of a cruder kind --- a "younger dynamic, violent kind."
I believe that the game has just begun to sit the older guys on the bench, and into retirement, earlier. You MUST be a Driver-Banger and a semi-crazed Wolfpack attacker, and the age line when that begins to fade just came earlier. We've seen what wins games. And it's swarming semi-violence plus great distance shooting, but Werewolf defense. ... and you need to be able to put two bigs on the floor at all times (the second of whom "hides" behind the prime defender and swats the shot away --- OKC is the prime example of that.)
"Offensive players only" become a killer liability in the playoffs. See Doncic. See even Brunson ... or Towns. Only Jokic's incredible skills allow him to become a positive in this new ball. But you almost can't count him as one of your defensive bigs, and certainly not a swarmer. It's why him having Gordon is not enough.
Who's winning? YOUTH. Crazy full court effort at all minutes. Old Men: I've loved watching your polished amazing skills. That game has gone away with the physicality and body stressing and blasting. I'm not sure that I really like the change, .... but I've played another game for many decades.
