Has he broken the ribs of someone his size? Is he absurdly powerful or something? I know he's good, but it appears he's just kinda tough for his size. Again, weight classes. He got slept by someone his size, so someone my size could sleep him to, hypothetically.
Has it occurred to you that the people who he has fought are people who have conditioned themselves for years?
Marquez isn't just someone. He is will go in the hall of fame and he would fukk you up too.
