I'm not sure he'll ever get there honestly, but I will disagree with you a bit on how he's used. I think he 'should' be putting the ball on the floor, that's what he's good at; he's a playmaker. our offense is structured around Clingan and right now the team is using him as a Clingan proxy on offense.
Similar to Scoot year 1, I think the team is trying to get him to simplify his game to the point where he's not the bloody vulnerable weak spot in the lineup that other teams attack repeatedly while he's in. They've recently gotten to the point where he can play 10m and not destroy the team. Now it's about adding in a a sprinkle of that playmaking without him being a turnover magnet, while keeping him out of foul trouble, and going from there.
