So when do we start the "Olynyk is the next Dirk" talk again?
When he gains some quickness and coordination and his arms grow three inches. 
He looks pretty darn quick and coordinated in that video. He scored in a bunch of different ways, on the break, with moves near the basket, pulling up midrange, etc.
Not that he's Dirk, but his issues aren't in his mobility. For a sophomore big man his mobility is actually very good. What he needs is some swagger. I remember Stevens saying last year that he wished Olynyk would be more selfish on offense, and try to take over a game. If he can do that, he's going to be a very effective player for a long time.
