UFC broadcaster Joe Rogan doesn’t give Floyd Mayweather (50-0 boxing) any chance at defeating Conor McGregor (21-3 MMA, 9-1 UFC) in the UFC – but thinks a fight against fellow MMA neophyte Phil “CM Punk” Brooks (0-1 MMA, 0-1 UFC) makes sense.

“Whatever the (expletive) odds Vegas puts on (a McGregor vs. Mayweather MMA fight), that’s cute,” Rogan said on today’s edition of “The Joe Rogan Experience MMA Show.” “If it’s 10-1, 100-1, I bet it’s going to be like 900-1. Something crazy. ‘Buster’ Douglas was only 42-1 (against Mike Tyson). If they’re smart, because Conor’s going to kick his legs out – he’s not even going to have a chance to come close enough. Conor’s going to kick his (expletive) legs out; he doesn’t have any chance. Then if he decides to shoot in and clinch, he’s going to clinch and he’s going to rag doll him.”

“Listen, if this fight takes place, Floyd doesn’t have a chance. (Against CM Punk), Floyd’s got a real chance.”

The idea of Mayweather competing in the UFC seems insane. After all, as incredible as the undefeated boxer was (and still is) in the squared circle, he doesn’t have any grappling experience on any level. He also turns 41 later this month.

Nevertheless, Mayweather is a master of promotion and has kept his name in the news with a few well-placed social media posts teasing his entrance to the UFC. Additionally, Floyd’s uncle, Jeff Mayweather, recently joked that Punk might make a suitable first opponent for Floyd rather than trying to go straight at McGregor.

Like most, Rogan admits the possibility is a bit ridiculous – but maybe just crazy enough to work.

“Unless CM Punk figures out a way – CM Punk is way bigger. Let’s be honest about that,” Rogan said. “CM Punk is a guy who was wrestling at like 190 pounds, cut weight to get to 170 to fight in the UFC. He’s not on anything. I’m pretty sure, at least according to everyone I’ve talked to everyone that knows anything about him, (he’ clean). That said, Floyd Mayweather is the greatest boxer, maybe of all-time – at least on paper he is. Unbelievable accomplishments; 50-0. I don’t care if the last fight was Conor McGregor. He’s still 50-0. That’s (expletive) insane. He’s on another level of everyone who is on another level.

“The question is: Can Floyd fight the same way he does with big gloves, with MMA gloves? I say this because Floyd’s broken his hands multiple times. He’s had some serious surgeries on his hands. Maybe they’ve cured it, and maybe they’re fine, but we’ve known for a long time he’s preferred puffier gloves when he’s fought. But he hasn’t had hand problems in a while. His hands looked (expletive) great against Conor.”

Is it going to happen? Who knows? The idea of Mayweather vs. McGregor in a boxing match seemed pretty crazy right up until it happened. And UFC President Dana White sure seems open to the possibility.

Mayweather vs. Punk might be surprisingly competitive. Mayweather vs. McGregor would likely be a one-sided beatdown, but fans – and haters – of both fighters would reach for their wallets if it was booked, and in the world of combat sports, if it makes dollars, it makes sense.

“I think (Mayweather) is going to make half a billion dollars (if he fights in MMA) – half a billion,” Rogan said. “It’s really possible. They really might rake it in with that fight. Floyd might be willing to do it. I think you could sell it. I think if Conor gave five, six months for a training camp. I can’t wait.”
