The modern boxing fan is wrong

It seems in the last 30 years that unless you win titles even if it’s not against the top guys in multiple divisions, then you have some p4p great resume. It seems that the modern boxing fan can’t appreciate a long reigning champion that cleans out their division in the modern era a guy like Hopkins. He’s only appreciated after he retires the same could be said about Golovkin. So why is it that a fighter hast to fight in multiple divisions or all of a sudden he doesn’t have a great resume. Does Tyson fury have to drop down to cruiserweight and win a belt to have a good resume? Was Hagler a fighter with a bad resume because he only won the undisputed Middleweight? Is Bivol suddenly a bum because he has only proven himself an elite fighter at 175? If Spence becomes undisputed, is he diminished because he only did it welterweight? The modern fan is wrong
