Dallas Mavericks star Luka Doncic says his defense is going to be better next season thanks to his weight loss. The Mavs' floor general reportedly lost as much as 20 pounds this summer.

Doncic says he's faster now and will be able to move laterally quicker moving forward.

MAVS.COM: Millions of us saw that photo of you on social media where you posed with a flat stomach while holding your dog, Molly. How much weight did you lose, because I heard you lost as much as 20 pounds?

LUKA: Yeah, but I didn’t check it. I just lost it, so I don’t have to worry about it, so that’s the key.

MAVS.COM: What has been the immediate results of the weight loss? And do you believe that’s going to help you going forward, especially on the defensive end of the floor.

LUKA: I would say I’m faster now. So (my defense is) going to get better, for sure.

Luka Doncic averaged 21.2 points, 7.8 rebounds and 6.0 assists as a rookie last season, winning the Rookie of the Year award. He recorded 24 double-doubles, eight triple-doubles, led all rookies in points per game and was second in assists per game.

For the Mavs to compete in the rugged Western Conference next season, they will need Doncic and Kristaps Porzingis to play like All-Stars on both ends of the floor. Both Doncic and Porzingis can average 20.0 points in their sleep, but they have to show they can defend at a high-level as well since every team in the West can score the ball effortlessly.
