They wouldn't.
It would still be 8 playoff teams per conference.
You'll just be doing less of the same thing.
I know there are 8 playoff teams per conference, lol, and I know the name of the game is make as much money as possible, but as someone whose favorite sport is basketball, objectively speaking, the NBA regular season is simply too long breh, if you want to win the long game and have a better quality product then you should shorten the season so the games mean more, and the top 8 from the East and West make the playoffs and that's the end of it, no gimmicks
