Chapo was very, very good but Duran just had too much of everything for him. Defense and chin are the differences. I agree with Mod-Mania. Thank you Double M
The way to beat Rosario was aggression, and to smother his offensive attempts by getting in his chest and pushing him back. That was Duran's raison d'etre. He crushes Rosario around the fifth or sixth.
I don’t think there are many people at 135 who can beat Duran.. Maybe Whitaker but I’m not even sure. Edwin Rosario was very tough.. Good punch. Lots of guts. But I can’t see anyone out brawling Roberto at that weight. Duran by stoppage after a good effort by Rosario in a crowd pleasing fight.
