I don't know that I could comfortably pick anyone to beat a prime Duran at 135.. Pernell Whitaker might be the exception but still not something I'd bet money on.. Hector was an awesome lightweight but I'd still have to favor the hands of stone..
I can't imagine that Macho does as well as he did against Chapo, who had him on the brink of disaster and gave him a very close fight.
Two different classes of fighter. You're talking about a very good lightweight vs the GOAT lightweight. Duran by dominant decision.
Duran easily. Rosario had Macho running scared with his power and Durans ferocity would have him skating in no time. Immensely talented but not in this.
