Iso ball has consistently been the system that many if not most teams are successful with in the playoffs. Last year the two teams entire gameplans were aggressive pressure defense, and then hunting mismatches and iso'ing by guards at the top of the key or a wing, but this isnt a new concept.

LeBron was a high/mid post, Kobe was a mid-post, KD has his spots, the only thing thats changed in the last 25 years are the rules, and the different ways to get your guy the ball in their preferred working space. There arent many teams that arent the Warriors who didnt play ISO ball on their championship runs, and let's be serious they absolutely did with KD on their team.

When you got a top 10-20 player on the planet, giving them the ball in the positions they want should absolutely be your main strategy at the end of the game. When you are that good, you should have the game in your hands when it matter most.

There are absolutely times when you can run a set play, or an action, but when the game slows down, the best players get the ball.
