He had a big gain in muscle mass in 6 weeks ,15-25pds of muscle, and this did not slow him down at the combine. This is plausable naturally, but not probable.
I agree with you that some people are more geneticallyblessed than others, but if he is genetically blessed than why did he lose the muscle mass so quickly? I have talked to people that know the human body(Biologists) and they emphatically say(in the their profesional opinion) a person cannot naturally achieve this muscle gain in such a short period of time.
'C.Biscuit97' I respect your opinion on this subject, but I have to disagree.
