I voted yes. Smart's natural position is PG, as his best offensive skill is passing. He has the vision, timing and accuracy to be the guy that initiates the offense. He won't be a ball-dominant PG who breaks down the defense, but he can be the guy who runs the initial action and makes a simple pass to put a teammate in a good position.
What he isn't is a guy who should be running off screens or spotting up for 3-- that is, a shooting guard. That type of action leads to contested 3's, wild drives into the teeth of the defense, all the things that Smart has proven to be bad at.
