I think Young missed a few defensive rotations, but they weren't that serious, and it was our impressive overall team defense that those mistakes didn't go as badly.
I think people need to stop doubting Young, and at least give him a chance to prove himself.
He hasn't ever really gotten over 20 minutes, so we haven't yet to see how well he's done. Give him a few minutes, and increase it, if he does indeed flourish.
