Probably over Vasquez for the WBA 154 title, everything that happened after that win didn't matter. That solidified him as one of the greatest boxers in history..
Vs. Azumah "the distinguished Professor" Nelson. Azumah was completely on top of the world, a long reigning two division champion and stepped up a division and got Sweet Pee'd
Azumah Nelson Buddy McGirt Jorge Paez Julio Cesar Vazquez Greg Haugen Jose Luis Ramirez Roger Mayweather Disobelys Hurtado
Azumah Nelson Julio Cesar Vazquez Buddy McGirt Juan Nazario Greg Haugen Freddie Pendleton Jose Luis Ramirez
It's between Nelson, McGirt and Vazquez for me. I did always think he beat De La Hoya, Ramirez and Chavez, though.
