Bilbos exactly right. The Ring magazine's writers invented the mythical title of P4P #1 for Sugar Ray Robinson based on professional opinion not formulae. It was in their professional opinion that in a hypothetical bout where both fighters would come in at the same weight class SRR's current skill and style would defeat his contemporaries. SRR's current dominance of his own weight class was also a major deciding factor because it was also in their professional opinion that you would have to look outside the Welterweight division for fighters that could defeat him. This factor seems to have been forgotten in present day arguments and is instead overlooked by which fighter has beaten fighters from outside their own weight class. Though this is impressive I think more attention should also be placed on fighters who dominate in their own weightclass than those who choose to fight opponents at dubious "catchweights" whilst seemingly avoiding perfectly suitable candidates, contenders and champions who are right in front of them.
