I can already foresee some interesting cognitive dissonance from his fanboys regardless of if Conor wins or loses.
Conor wins: "This cements his legacy as true GOAT! He dethroned the former GOAT by moving up to his greatest weight yet!" [The people who say this will be the same ones talking about how embarrassing Izzy's performance was against Anderson because he was old and shopworn and thus useless as a win.]
Conor loses: "Of course he lost! Anderson is four times his size, on PEDs, and the greatest middleweight ever! But look at how well he did before he lost and the balls he had to take the fight!"
