The complete lack of anything resembling the slightest of muscle definition across the shoulders and his getting pushed around tells me he's not even fat with some decent muscle underneath, like you'd see with an NFL defensive tackle. Even Big Baby has a decent muscular build below is flab. There's nothing resembling the v-shape in this guy through the torso.
Sim, just fat. Doesn't care enough to quit eating at all you can eat buffets. I have zero interest in this guy. Would make a decent story being the first Indian guy to make it in the NBA but that's really all he has going for him. If he was pale and grew up in Idaho and there was no story attached to him, would anyone care?
As someone who used to work in the fitness/nutrition industry I can tell you point blank, for a guy of his weight and body fat %, which likely is around 40%, losing weight is easier than it is for a smaller guy. Cuz dropping weight and cutting up was tougher. The lower your body fat %, the more your body fights to retain the fat. It's also far easier to create a caloric deficit when you're that overweight. Put this guy on a healthy, high protein/healthy fat 4K calorie diet per day(yes, more than any of us likely eat), on top of an NBA training program and he'd cut up quickly. Just has no dedication to his craft.
