Depends what Duran shoes up at 147. If we're talking Montreal Duran then Floyd's in for a whole lotta hurt.
once in a lifetime performance... i actually think thats prob the best one off performance in history.
1979 Duran -- the version which beat Leonard in Montreal -- would build a time machine, travel forward to 2007 and get into the ring after Mayweather-Hatton to challenge Mayweather to fight him. Mayweather would promptly retire the next day.
Duran pulled a Rigo vs Sugar Leonard and got KTFO by Tom Hearns. And don't even get me started on what Bill Joppy did to him.
