We are going on record, though. That's what 'greatness' is. I mean, I believe that a guy like Vitali would flatten Joe Louis, but I don't believe that Vitali is 'greater' than Joe Louis.
Because I watched him in real time as his career occurred. I have never seen a fighter like him before or since. He may have moved up to find other challenges, but, he was phenomenal at 160. I think guys like Monzon, SRR, and Hagler might take him, but, it is no sure thing. He was definitely better than Hopkins.
