I think he'll play, but I think he'll be having a lot of psychological issues that will prevent him from playing as he should. He's currently healthy to play, but seems to refuse solely because he can't play at the moment the way he wants to play (and in part because he doesn't trust himself with his knee just yet).
I keep thinking on when TA came back and the issues he had, and the mental problems he had to overcome trusting himself to jump for a dunk. I think Rose is going through that, but an exponential level to the point that he seems afraid to play.
