From watching a lot of T-Wolves games this season, I would say he certainly deserves it.
He had some explosive scoring games, as well as showing development in just about all areas as the season progressed. He has no major flaws, and has the athletic ability to improve in all facets of the game. No, his production didn't result in many wins, but that team is not put together well, and is bereft of established talent.
Kid is going to be really, really, good.
I wish he were on the C's!
