Its really not even development. I think Sim has NBA skills right now, today. But...BUT....
Sim, QUIT EATING. Seriously. I am not that guy. In general I think skinnies think too highly of their skinniness, and in particular think its a great thing for all people all the time. Not in a big man. Big men need bulk to battle and snap the skinnies in two. But Sim, you don't have bulk. You have fat. And 100% not one doubt in my mind, you lose that fat, you have an NBA career. You have skills, you have immense size. I'm not saying you will be Shaq. But you have a spot in the league if, IF, you. Quit. Eating. Stop it. Whatever it is you're doing, cut back. Its the only thing holding you back. Hire a chef. Ask Vivek to hire one for you, whatever. Put a picture of Yao Ming on the wall of your workout room, and then set a goal of dropping 50lbs by camp. Work work work and you might be a real NBAer next year. Not many get that chance. Don't blow it.
