The ring mag did a review of the LW's in 1987 and they had Benny Leonard top with Duran second.
I dont think Alexis would have beaten Duran , Duran for me TKO's him late.
Sweetpea outpoints Duran UD .
Suger Shane outpoints him MD.
But these are all opinions , im happy for anyone to disagree as these are all fantastic fighters.
