Regarding the, "Complaining excessively gets you nowhere," and "When you argue too much, you don't get the calls," comments:
Have you ever watched LeBron play?
Russell Westbrook, Chris Paul, Tim Duncan, Cousins, Griffin, etc.
There's just as many guys who excessively complain, as there is those who don't. There's no correlation between them getting less FTs.
It's hard to say Smart is arguing too "aggressively" or "intensely" when we can't see what he's saying and we don't always see exactly what happened.
If he's arguing more than other players, it's much more reasonable to assume the refs are missing more of his calls, than it is to assume his complaints are excessive/unwarranted.
If he really is arguing too intensely, we're a lot more likely to see more techs than we are to see him get less calls (and he already only gets like 1 FTA per game).
I think instead of asking Smart to change himself and the way he's always played basketball, we should just wait until his time/effort in the league pays off and he starts getting calls.
