The problem is he hasn't been shooting well. He has been getting a lot of open shots, but hasn't taken advantage of them. Same situation with close shots to the basket
I also noticed he dribbles the ball a lot. It's not that he ball hogs, but there has been a very plays in which he held the ball instead of passing it around.
Of course, he is way better than our other backup point guards like Childs,Vaughn etc.
