This is just semantics. He can't really play point guard because he could never cover the other point guard. You can put him out there and let the offense go though him as a point forward if you want to call it that, kind of like what Evan Turner does. If that is what you mean, then that may not be a bad thing but I am not sure it is necessary or would necessarily accelerate his development.
I ask people to think back on Avery Bradley's rookie season. He was not emotionally ready for the NBA. He was freaked-out, overwhelmed, just like Young was last season. But Bradley matured albeit slower than most NBA players and found himself a role in the NBA. It is hard to say what we have in Young, this is a big season for him. He will need to show solid improvement on the varsity team. If he can't play himself out of the D-League this season, his chances of ever doing it will diminish in my mind. He is a very young man still so he still has time to show us something.
