I won't even try to be a scout or basketball analyst because I am not, and neither is anyone on this board, as far as I know.
There are those who will harp on how terrible he is no matter how good he is and that will never change. It's like that for most players. No one can please everyone.
Again, I will say I believe he will wind up starter PF on a contending team. This is my own personal prediction. Why? I see that he really has no ceiling. Not yet, anyway. It's way too soon to tell, and just stating that you don't agree because other players you have known have reached their ceiling earlier, is ridiculous to me. As long as he stays motivated he will keep getting better. I don't have any reason to doubt that. His lack of length is made up for by his quick feet, quick reflexes and ability to overcome his limitations to the extent that he continues to improve, in spite of them.
