C-Webb ripped him on Mike & Mike the other day:

I agree with a lot of what Webber is saying. Cauley-Stein will never be a solid starter on a team because he's a liability offensively, but he can have a Javale McGee type role where he brings energy off the bench but isn't on the floor long enough to cost you the game offensively.
