2018-19 NBA Preview: Areas of improvement for each Celtics youngster

#3 Marcus Smart - Decision-making

Cleveland Cavaliers v Boston Celtics - Game Five

For all the great things that Marcus Smart does on the floor which do not show up on the box score, there is one glaring weakness in his game that even the most one-eyed Boston fan will admit. Smart has been just a terrible volume 3-point shooter through 4 years in Boston, and while he should shoot 3s when left open because it's the best play for the team, there has to come a time in his career when he consistently starts making them.

The rest of Smart's game is about as good as it gets. He's a really good half-court set playmaker, particularly in pick-and-roll actions. He's pretty solid at driving to the basket. He's the best perimeter defender in the league not named Kawhi Leonard. He can legitimately guard 4, sometimes up to 5 positions on the court on switches.

But till the time that he begins to stroke 3-pointers at a consistent rate, he will never be more than a complimentary role player on any team. A great role player, make no mistake, but nothing better than that.
