Of course, Moore mentions Olynyk's T-Rex arms:
2013 NBA Mock Draft: Matt Moore
Kelly Olynyk, PF, Gonzaga: Incredibly short arms, but a solid frame and a good amount of offensive moves. Working with Doc might be perfect.
It's looking more and more that the Celtics' will either pick a wing man that Danny is in love with (although he really hasn't shown his cards yet in terms of a SG or SF) or the best available big man in either Olynyk, Plumlee, Dieng, Saric, Gobert, or Adams.
