Because the heavyweights are essentially the best fighters the sport has to offer. Consider this; Floyd "The Best Ever" Mayweather wouldn't be able to beat a single one of Wladimir Klitschko's opponents, whilst Klitschko would walk through all of Mayweather's opponents in a single night.
Because the heavyweight champion is the champion of boxing. The lightweight champion is the best boxer who happens to weigh 135 pounds for five minutes the day before a fight. The heavyweight champion is the best boxer period.
You need to get that overhyped protected weight bullies nuts out of your mouth. Usyk vs Fury is far more of a technical/and interesting fight than Spence Crawford and they're a good 60-100+lbs heavier
I would like to know how crawford is a weight bully at WW, his 3rd division. No problem, anyway, I dont care.
