Joe Duffy is in an interesting position when it comes to the noise surrounding the rumored mega-fight between Conor McGregor and boxing great Floyd Mayweather Jr.
Not only does Duffy stand as one of just three men to ever defeat McGregor inside the cage, but he also is one of few MMA fighters with legitimate professional boxing experience, having racked up an undefeated 7-0 record inside the ring. So when he looks at what McGregor could be up against in Mayweather, Duffy can’t help but think his Irish countryman is setting himself up for defeat.
