He has to stop commenting Olynyk will be a great player in the league. It isn't fair to fans nor Kelly. Guys at the local YMCA have high bball IQ as well. Think great careers in the NBA require a bit more than that (i.e., not being a stiff, physically incompetent defender at his position).
KO is taking some time to get the swing of things in the NBA, but he's not a 'stiff'--whatever that means other than "bad, tall, white player without athleticism". He gets up and down the floor with the best of them and actually did quite well on things such as agility skills at the draft. He's already one of the better players in his draft class. And I think you're out to lunch impugning his BBIQ.
Tommy knows basketball at the NBA level, including the talent and skills that can't be taught, as well as the physical improvements that come with age and training.
Among qualified rookies, KO is
-8th in points
-7th in rebounds per 48
-5th in FG%
-5th in FT%
-11th in Assts and 13th in Assts/48--as a center!
-9th in blocks/48
-16th (below his draft position) in TOs/48
-2nd in fls/48 (such is a rook's freshman campaign: Bennett's the only non-big man among the top 7, at least KO's getting his induction out of the way this year

)
KO also has a decent 105 defensive rating for a rookie big man. In the first half of his rookie year, his per 36 stats are 13.1 points, 8.5 boards and 3.0 assists; but anyone who has followed his career knows that he can play better--and should expect that he will.
7-footers famously take longer to mature physically, to adjust to the NBA competition, and in terms of their game than smaller players. KO is a rare 7-footer in that he has a complete game that he is conscientiously trying to execute while taking in all there is to learn about playing at the NBA level. He also, of course, was late moving to the frontcourt positions, so he's still adapting his game there as well.
Jeesh!
