This post will not attempt to say that Smart is a good shooter. The stats don't back that up. His form is not consistent, and his shooting has not been consistent.
However, I want to put some stats out there that indicate he is not as inefficient of a shooter as many people think.
TS%: True Shooting Percentage - what a player's shooting percentage would be if we accounted for free throws and 3-pointers. True Shooting Percentage = Total points / [(FGA + (0.44 x FTA)]
In Smart's rookie season, Smart (49%) was the 59th point guard in the NBA. Which is terrible, but he wasn't the worst in the NBA.
Sessions, Mack, Walker, Cole, Rivers, Fredette, MCW, Exum, Payton, Burke, Price, Pressey, Rubio, Rondo, Robinsion, and Ish Smith were all worse than Smart, ranging from 43-49%.
There are several names on that list that are fringe NBA players, others who are elite prospects, others who are role players, others who are starters and potential all-stars. But that list at the very least indicates that Smart can contribute to a team offensively at his rookie efficiency.
What about this year?
Smart is 70th out of 73 point guards this year at an abysmal 45%. He struggled for a stretch after his injury, but it seems like he is starting to come into form now. I hope that by the end of the season he will be higher than this, or at least get back to his efficiency as a rookie.
The three below him are Grant, Cole, and Mudiay (who is on pace for historic inefficiency at 40%). If Smart can get back to his below average level from last season (49%), he would be ahead of Lawson, Rubio, Napier, Payton, Nelson, Vasquez, Ish Smith, Rose, and Huertas.
From 49-50% are players like Irving, Schoeder, Prigioni, Rondo, Udrih, Neto, Rivers, Russell, MCW, and Stuckey.
Conley, Wall, Knight, and Clarkson are all in the 51-52% range.
As far as efficiency goes, he is not in terrible company. If he can start making his layups (comon Smart!!!) and shoot 30-33% from three, he could easily get into the 50-55% range, which is good company.
Again, not saying that he is a good shooter. Just trying to bring some nuance to the conversation.
