I have been a big Olynyk fan since day one, but I always get a little nervous when he has a promising stretch of play.
Hopefully, he has matured enough where he can get to the point where even if his shot's not dropping or he's not feeling the flow offensively, his defense and rebounding don't drop to levels where he's barely playable.
In regards to the dunks, it looks to me like in the last few games, Kelly has really started to learn to add good, useful off-the-ball cutting to his game. To me, that's a big evolution for him. If he's going to be a perimeter player offensively, it will help his game tremendously to pick up a few easy buckets a game by making timely cuts when the defenders lose focus on him.
