So, instead of 4 teams, there are three?
That's how the NBA has always been because great players are such a larger part of the equation than any other sport. It was Lakers vs. Celtics throughout the 80's and the only slight dips in that was when the either team screwed up, got injured, or got old because it's possible future franchise player died of a cocaine overdose. It was the Bulls vs. Everybody Else once they beat the Pistons as nobody outside of NYC ever took the Knicks seriously and the West was always one team taking it's shot at the King and missing, only the challenger changed each year. Then, it was the Lakers vs a destroyed East, with the Pistons getting incredibly lucky one year with the Spurs & Kings causing problems.
The truth is, even if somehow Durant, Kyrie, and Draymond were all on seperate teams and are replaced with replacement level players on the Warriors and Cavs, that'd just mean the Cavs and Warriors might take 6 games to beat some teams in the earlier rounds than 4. Having the best player on the floor is such an insane advantage in basketball than unless spots #2-5 are better on the other team, the best player will prevail and sometimes, not even that helps until the Finals (see any Cavs run pre-Decision).
