So right now Mayweather is sitting around -2500 to beat Conor. Mayweathers last fight against Andre Berto he was around -3000. Berto is 31-4 and a former world champion. And he was a bigger underdog than Conor is... Mike Tyson was like -5000 against Buster Douglas. Again Douglas is miles better at boxing than Conor. Conor should be at around 100/1 underdog here. He is way worse than anyone Floyd has ever boxed and he isn't just boxing a run of the mill boxer. He is boxing the greatest boxer of this era who is 49-0. It's mind blowing.
