He does, but I've noticed he also checks out mentally sometimes and I think that's because he goes for stretches on offense without touching the ball. I can remember the last game, there was a possession where they basically played keep away from him on offense.
I'd try giving him the ball and let Westbrook or Beal set a screen for him and see what happens off that. He either gets a clean lane to the hoop with both defenders trying to cover the pass or Beal/Westbrook get a nice look
