In 2010, Joe Duffy took on a young and raw Conor McGregor at a Cage Wars event in Ireland, and Duffy tapped McGregor out in 38 seconds.

Obviously, a lot has happened since then, with McGregor rocketing to the top of the UFC’s featherweight division and dethrone the great Jose Aldo in 13 seconds.

Duffy, meanwhile, has gone 2-0 in the Octagon, and fights Dustin Poirier in the Fight Pass prelims of UFC 195 tomorrow night. The notion that McGregor and Duffy would eventually meet again is a tantalizing one – so of course ace scribe Jeremy Botter of Bleacher Report has devoted some ink to the subject of Duffy.

That was in 2010. Nearly five years have passed since Duffy beat McGregor on that night in Cork City. At the time, it was just one up-and-coming fighter beating another. It happens in cities across the world nearly every day of the week. Sometimes, the fighters involved never make something of themselves. Sometimes they do.

McGregor clearly falls in the latter category. The loss drove him back to SBG, and he began a winning streak that continues to this day. He also transformed himself from a mostly quiet and humble kid into the best talker in the sport, which in turn made him rich beyond measure.

To the casual observer, the switch in McGregor was flipped overnight. But Duffy doesn’t believe that’s the case.

“I think it was always there with him. He was always that personality down inside. It’s just that obviously the bigger he got, the more it grew,” he says. “But money is a huge part of this sport. It’s still a business. Whatever your opinion of him, you pay money to sit down and watch this and to watch him fight.”
