Smith casts shadows on Luka Doncic's transformation with concerns about defensive effortsStephen A. Smith is not convinced that Luka Doncic's physical transformation is enough to elevate the Lakers star to another level. On the July 29th episode of "First Take", the ESPN analyst doubted Doncic's ability to maintain his transformed body and utilize it in defensive plays."The brother is phenomenal. He's an offensive talent, there's no doubt about this. But there's a difference between getting in shape in the offseason and staying in shape during the season," Smith said."The conditioning is obviously imperative but does that mean you're gonna move without the ball instead of standing around and recieving? Does it mean that you are gonna up your efforts continously on the defensive side of the ball?"Later, Smith said that he was happy to see Doncic work on his conditioning, as it has been his Achilles heel throughout his career. However, he also remarked that the Lakers star's efforts in the offseason will truly show their value when he starts to play more defense during games.
