He's playing limited minutes, and the rest of the guys are doing so well he's ok with watching them score.
He's been taking a lot of 3pt shots because it's easier and less risky than driving the lane. He's always taken a beating when he does.
I'm not making excuses for him. In most games he shows he's clear got it still. Before the slump, his numbers were fine, and he was scoring 25 points in 30 minutes.
