Well going even deeper Floyd changed the game by showing nikkas you can be your own promoter. The Paul's came into boxing with a big ass built fan base already having millions so they said fukk it lets create and corner a market
I can say UFC does a pretty good job of promoting and hyping fights between nikkas I could care less about
It's the boxing nikkas who should be ashamed. Outside of Deontay Wilder a few years ago boxing stopped having compelling stories and hype and let the non boxing nikkas take the game right from under them
That's why the likes of MacGregor, Cena, and Dewayne Johnson were dangerous in the eyes of their respective promoting bodies. The brand is supposed to supersede all and be a funnel to attract talent to use for financial gain. You get some pissants desperate for a big break, and you keep them reliant on your scraps while you get the lion's share.
Enter Cena and Johnson who started to become bigger than the brand and expanded into Hollywood. Now they can make their production companies, and start raking in money while using WWE as a parallel funnel for exposure. MacGregor was the same way. Most of the UFC cats had to beg for fight of the night bonus. MacGregor was able to sell tickets off of his Muhammed Ali inspired trash-talk. He was the face of the UFC for a while there. If he really wanted to, he could have probably had a bidding war between UFC and its competitors, if not started his own promotion. Imagine being both the carnival barker and the main show simultaneously. McMahon and White had to nix anyone else using their promotions as a launch pad.
Those boxers need a lesson in showmanship, cause nobody is going to give a fukk if there isn't a story to sell.
