Marcus Smart cemented his status as one of the NBA's best defenders after a First Team All-Defense selection last season, but he's been exceptional on that end of the floor in each of his first five seasons with the Celtics.
We notice his sharp instincts, tenacity on and off the ball and the grittiness he shows when he guards players much taller than he is. But what probably goes most unnoticed are his fundamentals, and Celtics assistant coach Jay Larranaga detailed how fundamentally sound Smart is on the defensive end of the floor in Adam Himmelsbach's latest story on the team's heartbeat.
Marcus is a live example of the most fundamental defense you can teach. Every year you bring in new players and you’re trying to teach them NBA defense, you have an example of a defender that has been the most fundamentally sound defender I’ve ever been around. So you can say, ‘This is how guard a corner split: Watch Marcus. This is how you get into the ball and direct it with active hands: Watch Marcus.’ You always have a guy right there to tell other players, like, just watch what he’s doing and try to emulate it.
Since Smart entered the league, Brad Stevens has had a really hard time taking him out of games. He's been a starter or a key reserve in every season of his career and has been a staple in Boston's closing lineups as well.
Here's a look at how the Celtics have ranked in defensive rating since Smart's rookie year in 2014-15:
Without Al Horford, who was a part of the last three Celtics defenses and Aron Baynes, who was a part of the last two, Boston will have to overcome a glaring hole in the frontcourt on defense. While Smart has expressed his confidence in playing center in the past, Stevens will have to rely on ball pressure to ensure his team stays strong on defense.
And there's a good chance Smart is leading the charge in that department.
