An algorithm can only use quantifiable evidence. It can’t take into account the eye test. I’m not sure how boxrec ranks its fighters, but even its rankings of current fighters is pretty bad. It also can’t account for off nights or losing to known cheaters. There are so many things that an algorithm can’t account for that it will never be a good list.

Although when we humans do it, we give completely different lists so maybe we are just as wrong.
