Mayweather was knocking guys out when he was fighting at 135 and below. One of the greatest puncher in the history of that weight class. Even as he moved up the bigger guys that he was fighting we very cognizant of his power, especially his signature jab to the body and never attacked him recklessly.KO Power/Power punch is a gift, you're born with it or not, guys like Jones, Colby and Floyd will never get that godlike power that guys like Usman, Francis, Black beast, Mark Hunt, Tyson are born with.
they can train for years and will always be a pillow hands.
