WATCH: Why Marcus Smart is the Boston Celtics’ secret weapon

The Boston Celtics have a secret weapon in Marcus Smart, who — while known for his defense — has become a consistent 3-point shooter and crafty distributor.

The Boston Celtics have a secret weapon in veteran guard Marcus Smart, whose elite defense have made him an invaluable component of the Celtics rotation.

He’s not only one of the most dogged backcourt defenders in the NBA, he’s also not afraid to switch onto pretty much anyone — and has demonstrated he can defend even the stoutest of bigs for key possessions.

But it is not just his defensive acumen that makes him so valuable of a player; after a rough start to his career as an offensive option — at one point he was the worst 3-point shot with significant attempts in league history — the Flower Mound native has become a reliable threat from beyond the arc, connecting 34.8 % of the time.

And as we have noted recently, he’s also a quite capable floor general, able to sling dimes with pinpoint accuracy.

Taken together, his current $12.5 million deal is one of the best values in the league; for a more detailed analysis, watch the video embedded above to hear all the ways the Texan whirlwind contributes to winning games for the Celtics.
