Look it is what it is,Chavez jnr did it and so does Canelo,one has to give Canelo credit for being such a pro that he can make weight whenever he feels like it,you could say it's Canelos trump card as nobody else can do what he does and still perform,so he uses something to help him make weight,who cares,if it's within the rules then it's fair?
it's disgusting really. the man is a coward . he would greatly outweigh GGG too but not enough i suppose. unless he is weighing 25 or more than his opponent, he is not willing to do it.
