Floyd looked old because he fought a fight that he shouldn't have. He tried to brawl with a brawler, he won't fight the same vs. Porter. Porter is that dude but I think Floyd still beats him.
This is the problem I've had arguing about this fight. How does anyone truly know that Floyd chose to fight that way? Why can't it be that Chino forced him to fight his way out of trouble? From the first round, Chino was on his ass like white on rice.
I'm not one of those nuts that will say that Chino won. He didn't. But to deny that he controlled the fight just as much as Floyd would be cruel to the science.
