I think Nunes could take McGregor out.
Doubt it.
She'd probably back out the day of the fight.
Connor would wind up fighting, and beating, someone else on the card.
That said Mayweather will win tonight because of his style. He will jab and run his way to a points decision, as he always does. Floyd is not stupid. He's not going to stand in there and give Connor any chance, at all, to land any big left hands.
It will be a tremendous let down of a fight, as all Mayweather fights have been for years, because they're all boring.
I'm at work so I don't get to see it but, boring or not, I'd be watching it tonight with my friends for the off chance that McGregor gets the chance to land some nasty lefts and shocks the world.
It would make my night if he KO'd "Money" and ended his perfect career.
