Sensibaugh doesnt chuck... He just sucks at passing/making reads.
I'm convinced that he would be a more effective player if he was actually selfish and shot it every time instead of trying to make a play for others. He just becomes a turnover machine when he makes decisions.
It's cool to give him opportunities to try to develop that part of his game, especially in summer league, but his real future role in the NBA is as an efficient gunner.
