What Does This Really Good Series Mean?

Jimmy butler seemed to be much better in the post season than he was in the regular season. Kevin durrant is the best example of this for something like the top ten vineo, where you have two completely polar opposite series that happened back to back. And do i think there was a huge difference in keven Durrant as the player in when was that? Like, july of 20 21 and may of 20 22? I don't see a lot of evidence that there was.
