It looks like Conor McGregor is fucked to be honest. If Mayweather digs the body for a couple of rounds + some accurate jabs McGregor isn't going to be able to keep up and he may even get KO'd by Mayweather.
McGregor must KO him in the first 4 rounds or else he may get hurt.
I also saw that interview that Shane gave. I think we can't question him because he went toe to toe with Floyd specially in the later rounds and we saw what Mayweather did to him after he hit Mayweather in the face and almost got a KD.
Mayweather will really put a display on this fight, defensively and offensively. I think his punches has been underrated by his opponents but I honestly thinks he hit as hard as anyone from 147-154 lbs specially his overhand right and his vicious left hooks. If any of this two hits Conor square up, he will either go down or Floyd will score a KD.

Imagine if Floyd hits Conor with that.
