I’ve been near enough to each of these guys to speak with them on more than one occasion. MJ is naturally the largest man of the group, and while he looked very muscular in photos he was actually quite wiry. He is quite thin now.
Mo is small man and proportionally put more mass on his frame than MJ, IMO.
Andre is really little. I mean tiny. He may have put more muscle on his frame than either of the other two, but started from nothing. He was wired though and really tightly wrapped. His reaction to getting his ass whopped in Madden Football something to behold
