I think both Big Floyd & Roger took more chances than PBF. Roger defo had more pop than Lil' Floyd (Punching Power) & Floyd Sr. defo was a certified speed demon with great aggression. Both were good counter punchers & defensesive fighter's Sr. more so. it's a safe bet to say, Floyd Jr. is a mixture of both Mayweather's.. with maybe a tad bit of Jeff's footwork mixed in aswell. add also to that Jr.s great reflexes and better chin. a true rep of the entire Mayweather flavor.
Mayweather perfected his father's defensive style - shoulder roll, side to side parrying, and footwork. His uncle took many more chances and paid for most of them.
watch Floyd Sr.'s fight with Ray Leonard that is how you should kick the crap out of Mayweather Jr. No offence meant for Sr because i love him, but his son is a punk
