Olynyk, I think, would be a surprise. He dominated one year in college as a very polished 4th year player with size and skill, but even that was a surprise. He's never been looked at as a potential star.
I don't know, if only because Olynyk seems more capable of putting up bigger scoring numbers than Smart, and the ASG tends to be biased in that direction.
The biggest issue with Olynyk making the All-Star game based on scoring is that he'd need to play at least 32+ minutes a game to reach the scoring totals he'd need to contend for that spot. I rather doubt we'll ever see Kelly carve out such a large place in the rotation, if only because he'd need to avoid fouling so often and have the confidence and fitness to take a lot of shots despite drawing defensive attention.
Anyway, I was mainly trying to highlight that there's a divide between expectations based on a player's pedigree and expectations based on a player's game.
On the one hand, some guys, like Smart, might not "surprise" if they blossom into an All-Star simply because they were a star in college and got drafted in the top 10, even though they don't show a lot of evidence of having that kind of game early on.
On the other hand, some guys might not surprise when they make an All-Star team because they were always the sort of player that showed "flashes," i.e. they made exciting plays occasionally and generally had tantalizing measurables and athleticism. Giannis is the first guy who comes to mind.
