Close but i'd say duran maybe even by k.o.
I don't know if there will ever be another duran.....
There never will be, but it's safe to say there will never be another Chavez either. Both guys were some of the last old school fighters around. They both loved to fight and showcase their abilities for there fans. People bash both guys for having "padded records", but the bottomline is they just loved to stay busy and fight b and c-level opponents in between their big fights.
Roberto and Chavez at prime, would be THE WAR! They had the heart of lions, the strength of elephants and durability of wolfs. But Duran takes it by an inch.
