Re: duran v leonard greatness comparison.
Duran was a street fighter with brute power who could be easily beat by pure boxers. Jumping weight was a result of him eating like a pig. More than than half of his LW opponents were nobody's.
SRL did the equivalent of a Tim Bradley moving up and beating Chavez Jr in his career.
Both great but SRL has the better skill, amateur and and pro pedigree to slightly edge him in greatness imo.
