Genaro Hernandez and Lehlo Ledwaba are comparable. Pacquiao over barrera is in the discussion of greatest wins of the last 50 year right along side Ali over Foreman, Bowe over Holyfield, Sanchez over Gomez etc
Pacquiao Barrera 1 is one of the greatest wins since boxing was televised. Do you know how rare it is for somebody to knockout a prime ATG the way Pacquiao did to Barrera? Pacquiao took his soul. It's up there with Haglers performance against Hearns. It was that special.
Sven Ottke, Joe Calzaghe, Rocky Marciano, Ricardo Lopez are the 4 best fighters of all time since they were undefeated. Being undefeated is the one and only thing that matters in boxing.
