Probably Smart is overall right on average expectation for a #6 pick.
I do think he is underperforming my "hopes" for him.
By year 3 I was hoping for at or near all-defense level defense and something like 32 ppg, 14-16 ppg, 5 rpg, 4-6 apg (depending on his role and teammates, ie more assists if no IT to handle the ball), 1.5 stls, 0.5 blks, 2.5 TO (depending on assists) and up around 35% 3 point percentage, 44% overall, 75-80% FT percentage on around 10-11 attempts per game or so, so he is well short on offense.
