ofcourse, but how small is the chance, if 49 BOXERS could not knock out him before. Maybe 1%? Mayweather is the best defensive boxer in the game right now, its almost impossible to knock out him..
I am not saying McGregor is bad, in UFC, he would kick Floyds ass. But this is boxing match, and if you watch McGregor vs Diaz, you will see, that he is not even that good at boxing
Oh I don't think he will win unless it is fixed. But he does stand a chance via KO. But I'd take an educated guess, if it isn't fixed it will be over very quick, and I doubt McGregor could give two fucks, either way he is walking away with a lot of money.
