I'm not saying he couldn't carve out a role as a four in the NBA. The league is still getting shorter. But he is far, far away from having the skill to be an NBA three or four. He needs better handles, he needs to be a much better screener, a better passer, and be able to finish around the rim.
One thing that really excited me last night was a quick release on his second corner three with the defender closing out. If that is repeatable... My goodness!
