It's a win for both fighters from a money standpoint, but everything else is a lose/lose.
If Floyd beats Conor's ass, especially early, people will be pissed. If Conor wins by knockout, or if the fight is an even decision, people will scream the fight was fixed.
Thats why this fight will be a one off. It was always about the money from the beginning, and I wouldn't trust anything that happens during it.
