Why have so many boxing federations? What’s wrong with having just one federation as a whole? one champ for each weight class and one belt?
That's why you got the recognition of the lineal champion in each weight class. You don't need a belt
That's been a problem in the boxing industry for many years. They cannot unify. The players within the industry are not willing to give up their power. It's about dollars and it makes the sport unwatchable.
