“We Broke the Mold”: Floyd Mayweather Claims Credit for Crossover Fight Craze

It’s been nearly eight years since Floyd Mayweather and Conor McGregor stepped into the ring for what felt like one of the most surreal moments in combat sports history. A boxing legend against the biggest name in MMA— one of those fights that didn’t seem real until the first bell rang. But it happened, and by the end of the night, Mayweather had done what most expected: he picked McGregor apart, took him into deep waters, and closed the show with a tenth-round TKO.
The fight itself was a spectacle, but its impact stretched far beyond that night in Las Vegas. It didn’t just break pay-per-view records and make an absurd amount of money— it changed the entire fight business. All these crossover fights we see today? The MMA stars jumping to boxing, the influencers putting on gloves, the endless debate about whether it’s good for the sport? Mayweather says it all traces back to that one night in 2017.

Even before the opening bell, it was clear this wasn’t just another boxing match. Conor McGregor was stepping into unknown territory, and referee Robert Byrd wasted no time setting the tone. "You're going to hear me say stop because I'm not going to wrestle with you, and I'm not going to grapple with you," he told McGregor, making sure the UFC star knew this was a boxing ring, not the octagon.
And for a few rounds, McGregor looked like he might make things interesting. He came out aggressive, landed a few shots, and gave the crowd a reason to believe. But Floyd Mayweather? He never looked concerned. He let McGregor work, let him burn energy, and once the fatigue set in, he turned it up. By Round 10, it was over— Mayweather closed the show in front of 14,623 fans, securing his 50-0 record and walking away with another nine-figure payday.

The numbers from that night were staggering. Showtime reported 4.3 million domestic pay-per-view buys and over $600 million in total revenue, making it one of the richest fights of all time. But for Mayweather, it wasn’t just about the money—it was about setting a new precedent. "Me and Canelo did record-breaking numbers, but I think the Conor McGregor fight was when we really broke the mold," he said in a recent interview.
That fight didn’t just open the door for crossover bouts— it blew the door off its hinges. Since then, we’ve seen former UFC heavyweight champion Francis Ngannou step into boxing, YouTuber-turned-fighter Jake Paul build a career taking on ex-MMA stars, and even UFC president Dana White entertain the idea of McGregor fighting in BKFC.

And Mayweather? He’s still making money off the trend he helped start, fighting exhibitions and proving that, even in retirement, he’s one of the biggest draws in combat sports.
Whether you love or hate the crossover fight era, there’s no denying where it all started. Mayweather saw the future before anyone else did— and he cashed in first.
