Conor boxing Floyd under boxing rules is like Conor grappling Dillon Danis under jiu jitsu rules. You're not going to defeat an expert at their mastered discipline.
Conor needs to fight the winner of Khabib and Tony.
Then why wouldn't Floyd take the easy $25 mil?
Let's be real, as good as Floyd is, he's a blowhard. Yeah he would be Connor in a boxing match, but he's still not gonna take the chance of losing.
That's the difference between him and Connor. Connor doesn't give a fuck.
25 mil is a fortune for any regular person.
It's an insulting figure for Mayweather, though.
