haymon is not in control. he's the dude that has the muscle in the boxing world to get things done for floyd. He makes the deals happen for floyd and is paid handsomely for that. I'm sure he's the brains behind the operation but its all in cooperation with what floyd wants to accomplish.
I'm sure he wants too but lets not ignore the politics in Boxing right now. theres 2 factions, GPB & TR. and they control every fighter not named floyd that matters. you got GB fighters fighting only GB fighters and the same with TR. So yeah, floyd can start a real promo company but who does he have that the public is familiar with? he's trying to introduce fighters from his gym on his undercards and nobody is popping off yet.
its not as simple as just putting up the money and doing the work, you have to have fighters and opponents that the public cares about and right now arum and oscar own all of them. Its remored that since Schaefer left GB that he's working with floyd on a company but truthfully winning in boxing promo if your not GB or TR is like winning in politics if your not repub or dem
