Fair enough point, but I do rate Ricardo Lopez higher. The reason is because his record, although undefeated, does him no justice. But in an opposite way. Whats on paper is only a part of it for me. Watching his fights you get the feeling you are watching a spectacular fighter. Its also in how he won. He usually dominated his opposition flawlessly. So truthfully, his opposition wasnt HOFers, but he destroyed worthy opponents. Calzaghe was a very good fighter, also undefeated, but struggled a lot against B level fighters. On paper, I guess you could argue they were to par with one another, but in the ring they werent imo. Being undefeated is an afterthought to me. Its all opinion I guess, its hard to rate a fighter based on anything other than that.
