Marcus Smart is the most interesting man in the world.

Well, at least that's how he's viewed in Boston.

Known as one of the most proactive players in the NBA, as it is evident in the video above, the 24-year-old Smart has served as the Boston Celtics’ best hustle guy since being drafted with the No. 6 pick in the 2014 NBA Draft.

The defensive hound has averaged 8.3 points, 2.9 rebounds, 4.1 assists, and 1.7 steals in 58 games this season.

The 37-22 Celtics are currently occupying the fifth spot in the Eastern Conference, and most likely played themselves out of a chance at the top seed in the playoffs, following a crushing 98-97 loss to the Milwaukee Bucks on Thursday.

The Celtics defense, led by Marcus Smart, were able to hold Giannis Antetokounpo “The Greek Freak” to one of his more stunted performances than most are accustomed to seeing.

Celtics head coach Brad Stevens told Gary Washburn of The Boston Globe that he hopes the team can hit its stride in the second half of the year, despite the loss.

“In a lot of ways that started in Philly for us, that mindset that we’re going to see what we’re made of with this long stretch,” Celtics coach Brad Stevens said. “This is a great opportunity over the next however many weeks to see if we can get better. That’s ultimately the goal. Our goal is to play the best that we could be playing in the middle of April when the playoffs start. Tests like this and moments like these, you can learn a lot about yourself.”

The Celtics will look to embark on that desired run on Saturday against the Chicago Bulls.
