Body types. I shouldn't have to explain that. Boxers are worse than wrestlers when it comes to cutting weight, remember P-Will at welter weight? He looked like Manute Bol. I've met Hopkins, he's a skinny fucker as well. Never met Silva, but I have seen in person, even from a distance the guy is huge. Brock Lesnar is only 2" taller, why not have him drop to to 185 and fight Silva?
