Why the hell does it even matter? Old man GGG can't knock out Canelo, Canelo's not knocking out old man GGG. How can it be anything else but another Canelo robbery?
I know you're new to boxing and have really applied yourself to learning about the sport so kudos for that, but know that fighting 1 lb above a weight class limit is a common practice sometimes used in non- title fights. Fighting one pound above the limit in a non title fight won't get you ranked in that division, and you still keep your ranking in your division. Golovkin himself has fought at 161 on more than one occasion against complete bums. Now 164, that is a SMW fight. At any rate, Canelo gunning for GGG in his first real MW fight was badass, you have to admit that.
Canelo still is the bigger name with more options, so if they fight again, it'll be at 168, or a catchweight above 160. I don't think Canelo cares to go back to 160.
The Red Headed Chicken STILL claims to be the World MIDDLEWEIGHT Champion. He needs to defend that bogus title or hand it back again like last time ROFL. He cannot make 160 legally & everyone knows it STRIP the fraud. But as we know Pollo has the NSAC looking after him. Thats why he practically gets away with murder I hope GGG tells him to stick his bogus titles where Oscar is reported to stick his kitchen utensils. He aint worth the bother
