I predict that this statistical anomaly will not last. Kelly Olynyk is not single-handedly limiting opposing teams' offense by 18 points per 100 (from 100 to 82 if I am understanding the quoted stats correctly). I know I am going way out on a limb with that take.
Olynyk is a nice player though. His range, court awareness and length allow him to prevail in a number of match-ups.
