I agree with jr_ . Olynyk is slow. I think this will change over the next few seasons, but, he has not yet become "natural" with his decisions/movements. He has been called for a boat load of traveling calls as, upon receiving a pass on the perimeter, he takes a "college step" before passing away or shooting. Just a rookie thing that hurts his play.
Another point. In summer league he demonstrated classic shooting form and FG%. I always joked that his form was so perfect he looked like that statue on the top of one of those AAU trophies. This year he has abandoned his shooting form the majority of the time and it has cost his outside shot. He has had a few games where he has "got it going", but, our team has not been able to effectively leverage it. Victim of the 10 man rotation.
Olynyk is a superb passer and has been more about "communicating the ball" this year than shooting. His open shot refusals have hurt the team and his game. I'm sure this will improve.
Olynyk suffers on defense against competent bigs (who doesn't?). Kelly Olynyk does not "play big" as his reach is limited and he's a rookie. I always saw him as a "really big winger" as he is not physically designed to succeed underneath.
I sincerely believe Kelly Olynyk is best coming off the bench as an "outside gunner". I'm not sure exactly what that is....but it sounds really cool.
