Nuggets coach George Karl isn't comfortable using either Carmelo Anthony or J.R. Smith at point guard.

Denver has been without starting point guard Chauncey Billups because of a groin injury lately and, at times, Anthony and Smith end up with the ball in their hands in a point situation.

"I'm definitively, totally against Melo and J.R. being our point guards. When it happens in the flow of the game, fantastic, but there's some games where I don't know who the heck the point guard is out there," Karl said.

"It's on me. I allow it, and I like freedom and creativity and versatility, but there's no question that Ty (Lawson) and Chauncey (Billups) should have the ball."
