The two biggest stars of mixed martial arts, Ronda Rousey and Conor McGregor, love to take shots at the biggest star of boxing.

To MMA fighters, braggadocios boxers like Floyd Mayweather sound crazy for boasting about their comparatively one-dimensional talents. To certain boxers, MMA fighters sound crazy comparing the two sports, especially when top-tiered boxers generate vastly larger sums of revenue.

Ronda Rousey has been most vocal across the party lines, calling Mayweather out last year for pretending to not know who she was. This year, when she beat him for the Fighter of the Year award at the Espy’s, she dropped her now-famous domestic violence reference and diss, “I wonder how Floyd feels being beat by a woman for once.”

Floyd fired back on Sportscenter, avoiding the commonly held belief that Ronda could actually beat him in an MMA match, and pointed at the money again.

“I’ve yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes,” Mayweather said. “When she can do that, then call me.”

On Monday, MMA’s second biggest star, Conor McGregor, jumped in to the mix in an interview with The Gaurdian. McGregor conceded that he would be bested by Floyd if they fought a traditional boxing match, but that’s as far as it goes.

“In a real fight I would dismantle him in seconds. Ronda would dismantle him in seconds—100%. When you don’t know how to grapple you don’t stand a chance,” he said. “For us, it’s like playing with a baby. People who don’t understand the sport cannot understand how vulnerable they are. There are always clinches and Ronda is a judo Olympian. She would throw Floyd on his head in a second. Me? I would knock him out. Cold.

“Mayweather might love money but he’s too smart to go down the MMA route. […] But if you’re talking about a fight that could generate half a billion—it’s this one. There’s never going to be another boxing fight like this. Only a cross-style match between Mayweather and me could generate that kind of interest and revenue. So maybe it could happen. I would certainly be up for it. I am capitalizing on every single opportunity. It’s a strong word, one of my favorite words: capitalize. I’m ready to capitalize on everything.”
