Read this criteria DIRECTLY from "The Rings" website and tell me how the hell Canelo is #2 RATINGS POLICY Results. This is the most objective criterion and takes precedence over all others. Performance. How a fighter performs in a victory or defeat can be a factor to determine his place in the ratings. Track record: A fighterÂ’s accomplishments in the recent past can be a factor to determine his place in the ratings. That includes quality of opposition. It's sad when you can't even get something as simple as rankings correct.
Ring is owned by GB and the rankings are done by a single person. There's no credibility there what so ever.
It's not "simple." Everybody has different opinions regarding every fighter, thus the relevance of every single fight on a fighters' resume will be completely subjective.
