lol how many games as he played let alone started at PG?
This is what 'development' is all about. He's a smart, tough kid and he'll work it out.
Brad Stevens coaching style is about slow development. He's restricting the shots he wants Smart to take- limiting his drives to the hole for now.
Eventually once Smart understands the offense and the fundamentals of this half-motion offense, he'll be able to manipulate it and add his own flair of offense when he sees fit ala Tony Parker (attack when you see an opening, keep the ball moving until you find an opening, and when a double team comes find your shooters).
We've barely seen him attempt to get to the hole which is a huge strength of his and this will come at a later point.
Rookie season 101:
-Learn offense
-improve 3 point shot
-improve passing
Forget about everything else for now.
Stay patient my fellow green fiends.
