A small maybe is the ufc did hold some money until his next octogon appearance which everyone including Conor and Dana were pretty confident it was going to be before the end of last year.
They were always going to have trouble getting him to fight for 10mill after the Floyd fight and are definitely smart enough to put that in his contract.
Also l think the Floyd fight was a 3 way co- promotion.
I'm not sure what the promotion arrangement actually was.....Mayweather Promotions and Showtime are two definites, but the 3rd is unclear. Originally Zuffa said they were going to help promote from behind the scenes....then they applied and were granted a license to be a promoter for the event....because as Bob Bennett explained, Mayweather promotions couldn't pay the opponent under nsac rules, so Zuffa had to be involved....
But when you watch the actual fight, Zuffa isn't mentioned anywhere as an official promoter in the introductions, it's just Mayweather, Showtime and MGM resorts lol
