Well, I did say against world class opponents in my original post which I'm pretty confident has never happened before or since I was just trying to make it a little easier If someone can find some examples of that I'd like to see them But I'd love to see one of a fighter achieving that against four world class opponents in world title fights
I'd say Teofimo Lopez has an even greater accomplishment in outboxing an "ATG" in his 1st real step up in competition.
