No one, thats why he he is destroying everybody in multiple weights, he fought on equal terms with GGG twice.
Do I wanna see a third war? Yes! Does it make sense for Canelo? No not really, it's lose lose for him. If he wins GGG was washed, if he loses he loses to a "washed" GGG Does it make sense for GGG? Maybe? He's taking a double risk, Canelo COULD win and also seriously damage him. He is coming off of punching a guys bicep off, and breaking a guys face.
The narrative has been that Canelo improved his boxing after Mayweather and adapted some of his technics. I think since GGG, Canelo has focused more on his power.
You learn more from a loss than you do a win and Clenelo knows he lost both those fights. In fact, he knows he got his ass paddled so badly in the first one he had to go and jack himself full of PEDs to try and gain even more advantages over the old man because he knew that even with the judges in his pocket to bail him out, and that even with his weight advantage and huge advantage in youth he still would not be able to beat the old man fair and square. But even if you want to be extremely generous to Clenelo and find a way to score the rematch in his favour after GGG turned slickster and jabbed his face off all night it's still a terrible look for him because he could only eke out a razor-close highly controversial win against an even older and more declined (and noticeably so too) GGG after jacking himself with PEDs. And this is just be speaking pure FACTs here. In fact, I don't even think I can take the credit for doing so because I believe I'm just a vessel who has put here by the Lord to channel his scared truth to my fellow mortal man on Earth.
Definitely. 24 rds with someone as good and as experiencd as GGG will certainly improve you if you come out intact on the other side.
