— -- Each week, ESPN.com writer and MMA Live Extra analyst Brett Okamoto provides his take on the hottest topics in the world of mixed martial arts.
This week, Okamoto squares off with ESPN.com senior boxing writer Dan Rafael to discuss the wild premise of a fight between retired boxing superstar Floyd Mayweather and UFC featherweight champion Conor McGregor.
The worlds of combat sports collide in this special edition of "Five Rounds."
1. Could a fight (under any rule set) between Mayweather and McGregor actually happen?
Okamoto: No! A fight between these two could only "actually happen" in the same way getting struck by lightning twice on the same day as you win the lottery could "actually happen." I'm going to get on a soapbox for one second (and one second only, I promise). It's saddening to me that all it takes for millions of people to start talking about this fight is Mayweather uttering the word "possible" and McGregor tweeting a photoshopped picture of the two looking at each other. The UFC isn't going to let McGregor box, and Mayweather is definitely not stepping into an MMA fight. If this one ever happens, it's in a professional wrestling ring where the outcome is written in a script. These two seem to be having fun with it though, and why not? If that's all they have to do to make national headlines, they'd be fools not to. If they're willing to have fun with it, then I guess Rafael and I can have fun with it. But know that to even address this nonsense pains me a little.
Rafael: No! How could it happen when they are both (well, at least one) retired? Seriously, this is such a joke but, hey, the bosses said my man Brett and I should discuss it because there are so many people interested in this nonsense that we might as well get the clicks, too. I like talking about real fights, not fantasy silliness that has less chance of happening than Cain-Abel II or even Muhammad Ali-Joe Frazier IV. But fine, I'll play along, briefly. Let's just say for a moment that is to be taken seriously (which it is not!). In which discipline do they fight -- boxing or MMA? That's a deal-breaker, right? I don't know McGregor, but I do know Mayweather and there is no way he gets in the cage. None. They could spend a week locked in a room and not come to an agreement on that pretty important element. Besides, does anyone really think UFC is going to let McGregor out of his contract to do this? I'll let the rest of the world do mental cartwheels over this nonsense while I stick to real fights. Are we done yet?
