Furthermore Smart is a specialist who is a lock down defender and high energy player. No one is signing him for his offense.
Other than running the offense, Lonzo wasn't exactly picked for his offense either (at least when it comes to scoring).
No question that for him to fully develop and reach anything close to the hype that surrounded him, he is going to have to improve his shooting, especially free throw shooting.
But if, as you said earlier, his floor is Rondo (hopefully a less abrasive version lol) that's not too shabby, imo.
