Wrong. He shot fine with it in college.It is s**t though, no player who flings the ball from one side of his face like Ball does is ever going to have a respectable jumpshot.
He's a no defense playing version of Rondo.
The problem with his jumper is that it prohibits him from creating a variety of shots off the dribble.
That doesn't mean he'll be a bad shooter though. He could easily be fine in the NBA at catch and shoot shots, stepbacks and jumpers when the defence sags off him.
