He is a really good passer, which causes him to look for the pass instead of his own shot. What he needs to realize is other players are less likely to get open shots.
So I missed the last game and am waiting until the black out is lifted off league pass to watch it, but the advanced statistics indicate he has been playing better defense lately. On the season his defensive rating is 108 (good for third on the team), but his defensive rating has been 94 in two of the last three games. I think if he stops picking up ticky tack fouls and is able to stop opposing teams on offense, he will be less reticent to shoot.
