I like Okafor playing along side one of the others, but it is pretty obvious either Noel or Embiid get traded and likely soon.
You can't risk hurting their growth by not giving them minutes and there is just no way you can play all three at the same time obviously.
I liked Porzingas and Mudiay more than Okafor and I have been consistent about my lack of interest in Okafor since January. I think he will be solid, but the guy is going to give you zero on the defensive side and isn't considered a good defensive rebounder either.
