In short, I dont' believe anything I read at bb.com. I dont believe most things people say in General. King Kamali said he gained 60lbs over a single summer because of his superior genetics. Point being, people love to "exaggerate".
EDIT: To give hiim the benifit of the doubt, I'll say the pics look pretty convincing. 50lbs is ALOT of weight in 10 months though, especially if it's all lean.
