He often guards opposing players taller than he is, using his physicality to make them uncomfortable and often causing turnovers or missed shots.[87] Over his years in the league, Smart's three-point shooting has improved.[88] His former teammate,Kemba Walker, describes the energy Smart brings to the game: "It's exciting. It's energizing. He just gets everybody going. Gets us going, gets the crowd going. Like I said, we just kinda feed off him. He just does so many great things. And propels our defense each and every night."[89]
