An argument can be made KO is actually better than Porzingis on ou team and in spots. Porzingis would be missing shots KO makes and want the ball more.
Still interesting though. As far as talent and a balanced team. IT, Bradley, jaylen, porzingis, Horford, rozier, smart ko etc is definately balanced.
If it were done it would be straight up. We keep Rozier, KO etc.. KO would then supplant Porzingis at times when he is on the bench. They are so similar though. Porzingis plays slower and blocks more shots.
