Mavs fan out there, did you watch the recent interview with Kristap Porzingis?
Look at his built. I've noticed that his body becomes more bulk up. Damn, what did he do while out on NBA (aside from involving into a brawl lol)? Like he isn't came from an injury.
Maybe others will see it as a disadvantage since he might become slow but for me, he will be like an athletic version of Dirk Nowitzki.
I am more worried about his shooting percentage rather than him getting slower.
When you are changing your body figure you may also destroy the way you shoot or how strong and mild a shot should be.
It needs to be trained while he is gaining more weight.
KD is one example of it. He doesnt go way far of making his body bulky to avoid losing his assassin shots.
But with the right method it might work.
Although it is true that gaining more muscle makes you gain more scale weight than fats.
