Jack Johnson is a famous example of a fighter who turned great defense into great offence, throwing a punch with the same hand he would use for a block. What other fighters were really good at turning defence into offence?
I'd say Bernard Hopkins and Jersey Joe Walcott could do it with footwork, taking a defencive stance or retreat and turning it into a beautiful attacking opportunity. Floyd Mayweather can do it. He can pot shot from a heavy lean and turn a dip into a shooting opportunity. Duran?
Duràn did it pretty much,he can parry punches inside with one hand and beat the snot out of you with the same hand too.
This. Peekaboo was meant to make aggressive, evasive maneuvers to put the practitioner in a perfect position to unload.
Also, Joe Frazier's bob and weave, and Jose Napoles working on third gear. Mantequilla was otherworldly.
