Depends on the weights and rehydration too I guess, 154-155 tops. Anything over that and it's a massacre IMO. Cameltoè hydrates to a light heavy and he ain't no skinny b1tch either.
I don't rate Brook's skills either, he went life and death with Porter, The Mecican would phuck his shyt up at 154.
I would have been fine with it at 155... Brook is not like Khan, he's not known for having a glass jaw and he does have power to keep Canelo honest.. Khan was a joke and everyone knew it..
Brook at 160 vs GGG though could be ugly..I don't think anyone will give him the slightest chance of winning which if he does, makes it even more of a great achievement...
