There is only one way to resolve the spacing problems that come with Nerlens Noel and Jahlil Okafor being on the court at the same time: turn Okafor into a three-point bombing stretch-four in the mold of Ryan Anderson.
It has to be Okafor. Noel is a lost cause when it comes to scoring from the perimeter. He is the owner of one of the most borked releases in the league and I doubt there is a shooting coach that can fix it at this point. Okafor, alternatively, has shown more offensive touch in a few months than Noel has over his entire life, and can already pretty much shoot threes. He was an errant toe away from canning one last game, and he looked totally natural doing it.
Embiid, though, might just have to trade him before he even sets foot on the court.
