In the NBA if you can't shoot the 3 you're not playing much, even as a 7 footer, unless you're absolutely excellent on defense and rebounding. The NBA is looking for the next Joel Embiid and Kristaps Porzingis for their posts.
Jahlil Okafor is a prime example, he's a 17-8 guy if a team gives him minutes in the post and allows him to shoot from the block but he doesn't defend well or shoot 3 pointers so he barely sees the floor most nights.
Clint Capela is a dominant rebounder and great defender so he gets to play. Andre Drummond is a great rebounder but not a great defender and he can't hit 3s, so two different teams gave up on him the last two years. On the Lakers he won't need to do very much but you can't build a team around him.
If you're 7 feet tall and can play outside you're probably the #1 pick in most drafts. So it's going to be harder for us to attract elite 5s if we don't allow them to play outside.
