All you people saying Kelly needs to lose fat or turn fat to muscle or whatever need to realize that he measured one of the lowest body fat percentages out of all the players at this years combine. What was it, like 6% body fat? He is not capable of losing any fat. Any weight he loses will be from muscle loss or hair loss.
He didn't measure "one of the lowest". He measured comfortably in the middle, but probably towards the lower end of big men, who typically carry more weight (and by extension, more fat) on their frame. So that's not bad.
It's worth noting, of course, that the record is from predraft camp. Sullinger was quite trim in predraft workouts too, and we all know how that worked out.
Also, he's not going to lose any weight by turning muscle into fat. That's not how it works (muscle is, in fact, heavier than fat). But regardless, he doesn't look good at this playing weight. One way or the other, his playing weight needs to be lower, since he's not going to outmuscle anyone, and he's not quick enough on his feet either.
