#4 Money
Just in terms of what the fighters will earn, possibly augmented by the insane PPV sales, sponsorships and TV viewership rights, this fight is a mini bank in itself.
With the completion of this fight, Floyd 'Money' Mayweather will chalk his career earnings above the mind-boggling $1 billion mark.
Let that sink in.
And although Conor McGregor's net earnings aren't even in the same ballpark as Floyd, the crisp paycheck he will make off this fight, north of $100 million, will still be his biggest single payday.
A lot of people have accused this fight of being nothing more than a money-spinner. And perhaps that's true. But why on earth should that mean that it isn't going to be an intriguing content anyway?
