I didn't have too many problems with Smart's shot selection last year when he was hitting >30% of his outside shots. I felt like it was important for him to work on his jumper. Given his lack speed and explosion, it's important that he has the threat of a jumpshot to create driving opportunities. My patience was predicated on the belief that with time and in-game reps his shot would gradually creep upward and become more consistent, even if he'd never be deadly from outside.
You can blame injuries in large part for why that hasn't come to fruition this year. Additionally, it seems like his inconsistent and flawed shooting mechanics contribute a great deal to his streakiness. This year he's been cold far more than he's been hot. I'm starting to wonder if he's just a poor shooter who had some good luck last year and maybe got left wide open a lot of the time. This year, teams are actually defending him.
All of which is to say that I have less patience for Smart's shot selection this year. He hasn't shown that he is willing and able to put the ball on the floor and attack the basket when the outside shots aren't falling. The only shot he seems willing to regularly take other than the three pointer is a one dribble pull-up from mid-range. That's a nice tool to have, but only as a complement to threes and layups.
Smart impresses every once in a while with a really astounding, acrobat finish inside. That's really cool -- I remember seeing such highlights before he was drafted, inspiring comparisons to Dwyane Wade. The problem is, to actually score frequently and efficiently, Smart needs to be able to get to the rim and score without having to complete an extremely difficult, low-percentage shot. Can he do that? I don't know. He might not be quick enough for it.
This is why Brad's been posting him up a lot lately, I think -- to try and get him going with shots near the rim. Problem: if you're 6'2'' and the only way you can consistently generate looks inside is by getting entry passes on deep post-ups, that's not a sustainable long term strategy (unless you're Andre Miller and your old-man-at-the-Y game is epic).
