You think running it back with the same principles is going to bring any other result?
Brunson can still play relatively the same minutes, but breaking up the time in which he and KAT share the court is going to be beneficial to everyone. The ball moves more and that feeds into the synergy at the other end when Brunson isn't on the floor. Having KAT, Brunson, Mikal and OG on the floor at the same time for the majority of the game doesn't bring out the best versions of themselves. That doesn't mean that lineup should be abandoned, altogether, but staggering them, allowing each player to touch the ball and work themselves into the game is a better strategy.
It'll also help defensively because they can surround them with more defensive-minded pieces.
This is an insane solution. They got to trade KAT or Brunson and for all the non-basketball reasons KAT is the odd man out, plus his contract will bring more back.
Trading KAT or Brunson is the "insane solution". You won't get players better than them, because they're not on offer. You have to make it work with them. Y'all won't get a better core than you have now, so it's all about maximizing them and surrounding them with the appropriate pieces.
