I said this in another thread. My eye test tells me that Smart's problems are not with skill, ability, or athleticism. His problems are with rhythm and confidence.
Whether its because of injuries, or CBS not force-feeding him, or forcing him to play off ball mostly the first few years, or endurance, or fan support, or not drawing fouls, or something else, Smart has not been able to get into a consistent rhythm for his game.
He's never going to be a 20 point a game guy. He's not the modern day version of a scoring point guard. He doesn't fit conventional molds. But he could be a 16, 7, 6, and 2 guy on 40, 34, 80 shooting.
He can create shots for his teammates and make unselfish plays. He can run the pick-and-roll. He can hit big shots. He can lead us to a win with 27 and 7 in a playoff game. He can get key rebounds to seal wins. He can get key steals to seal wins. He can defend the opposing team's all-star 7'3'' center (Kristaps), 6'7'' power forward (Milsap), 6'8'' small forward (James), 6'7'' shooting guard (DeRozan), or 6'2'' point guard (Kyrie).
Never let anyone define you by what you can't do.
