Luka Doncic's Achilles heel is catching up to Cooper Flagg, but he has plenty of time to turn this "weakness" into a strength.
No one can deny that Cooper Flagg is the best 18-year-old basketball player on the planet, but if he plans to get better, he has to better preserve his energy to stay on the court and make his reps count more. Conditioning was an important subject that led to Doncic being traded. Under most circumstances, it would be ridiculous to trade a multiple-time All-NBA player in his prime just because of his conditioning skill, but it still happened.
