Agreed, and there are many here who are talking about Johnson "missing" this opportunity with JOJ and failing to "coach him up" into the player he should be. JOJ seems like a good guy, and he is pretty good initiating offense with the ball in his hands. He also has a 46 inch vertical.
However, the more you saw him play, the more you could see how he struggled to be a part of a working offense, passing and moving without the ball. He struggled to make the right pass and to be in the right spot at the right time. And for a guy with the kind of athleticism he has, his rebounding was really poor.
He also struggled defensively in many ways. The fact is that some players have better instincts on how to play on a team than others do. He simply did not make the team better most of the time. And you can bet that coaches worked with him on these details.
I hope JOJ finds a spot that works for him. And I respect Johnson's decision to leave him on the bench after giving him multiple opportunities. If you're not doing the things that the team needs you to do, then you don't play. That's not a "miss."
That's trying to make your team better.
