Prior to his loss against Nate Diaz at UFC 196 in March 2016, Joseph Duffy was the last man to defeat UFC lightweight champion, Conor McGregor.
Unlike Conor McGregor, Joseph Duffy has a pedigree in professional boxing. The Donegal native was 7-0 in seven professional bouts prior to moving into MMA. While speaking recently with SevereMMA, Duffy discussed both McGregor and Mayweather Jr’s proposed boxing bout, and doesn’t feel too confident about his fellow Irishman’s chances:
“I just think Mayweather will win pretty convincingly. Whether he stops him or not, is another story. I definitely feel it’s a landslide to Mayweather.”
“I’m not sure (if Mayweather finishes McGregor). We’ve never seen Conor box. There’s definitely things to look at there. It’s hard to gauge. Obviously, Conor’s never fought someone of that level in a boxing match. I suppose until it happens, none of us has a clue how it’s going to go down.”
