because p4p justify's why an prime joe louis would beat an wladimir klitschko, when it is obvious than in real it wouldnt be so. (I hate wlad!) because a lot of fighters realy just win based on weighing more or being the stronger man. wounder how marquez would have done vs mayweather, had he been as tall as him, with the same reach weighed exact the same...?
It's really taken too seriously. The phrase started out a long, long time ago, and then Ray Robinson helped popularize it, but it's gotten way too "important" recently. I guess with a gazillion titles out there, there has to be some title that has more meaning, even if unofficial.
