I think he will have some big games, but overall, I would say 6.5 points and 3 rebounds per game. I think the game is going to be a little too physical for him to stay on the floor much.

Even though the nba will be a little physical for him in year one, at least he will try and not shy away from contact. This is the reason why he will stay on the floor. Olynyk can't "sky" but his ability to up quickly for 2nd/3rd tries is excellent. Sullinger, Varejao excellent
Mchale on Olynyk
“I like him,” said the Celts legend and current Rockets coach. “I like him a lot.
“I tell you what, he does some interesting stuff. I was telling our guys that it’s been a long time since I’ve seen a guy get an offensive rebound and just quick lay it over the rim like he did out there. No one else reacted. You play by yourself when you do that, because people aren’t reacting like you are.
I don't want to speak for Chris, but I would suspect that the concerns about physicality are more in terms of defense and rebounding. Olynyk was overpowered physically at times in college (and also in summer league, though you won't see that on highlight videos) - playing against guys who are not even close to the level of the typical NBA center or power forward.
You can see some of this starting at around 7::30 of this video:

But I think in his rookie year, the idea that he will be overpowered against PFs is plausible. Think about it, he will be covering guys like KG, Duncan, Stoudemire, Bosh, Horford, Griffin, West, Boozer, Milsap, Randolph etc...even the typical backup PF is going to be on another level compared to guys Olynyk faced in summer league and college.
If you go back to Al Jefferson's rookie year, he was in a similar situation. He clearly was ready offensively, but on the other end he was tough to keep on the floor. In Al's case it was maybe more about being young and not understanding the game - he had from day 1 physical gifts and rebounding ability that Olynyk lacks.
Jefferson ended up averaging 6.7/4.4.
