I think your point about Porter is a fair one. Not sure how that stretches to Doncic though... you don’t think Real Madrid which is one of the richest sports clubs in the world has extensive resources for fitness and training?? Or that basketball hasn’t been Luka’s job for 3 years already??
I don't watch the Euro stuff outside of a few times a year but as a soccer fan and seeing how the US is overly focused on athletes to the detriment of skill players I tend to believe that we'll see some pretty significant changes to his body composition which might erase a lot of Doncic's perceived deficiencies.
