Conor McGregor made the jump to boxing, in order to take on Floyd Mayweather. After reports that UFC President Dana White wanted to explore having Mayweather reciprocate, by making the jump to the “Octagon,” Mayweather said he had no interest in doing so.

That unwillingness to repay the favor, brought forth a verbose and poetic Twitter taunt from McGregor. The two-division UFC Champion tweeted:

McGregor then followed-up the taunt with a tweet that reuired no words, only a picture of him and the two UFC belts that he owns:

According to Bleacher Report, “I never said I was going to fight in the UFC. I didn’t say that,” Mayweather said (h/t MMA Weekly). “I said if I wanted to and what I could do. I’m not going to do it though.”

Mayweather made those comments after reports emerged that UFC President Dana White’s promotion company was actively pursuing an MMA fight for Mayweather.

The boxing match between Mayweather and McGregor, drew 4.3 million PPV buys. The second highest earning pay-per-view in history, behind only the Mayweather-Pacquaio fight. While an MMA bout between McGregor and Mayweather would no doubt be a huge draw, it’s difficult to see it reaching those types of numbers.

Simply put, Mayweather has no chance against McGregor in a real fight. Real, in this case, meaning any kind of fight where the opponents aren’t restricted to only one form of striking. If McGregor is allowed to use kicks, knees, elbows, wrestling, BJJ; in short, all the techniques that he has practiced and mastered for more than a decade, the fight will not last one 5-minute round.

For all of Mayweather’s wizardry inside the boxing ring, and his greatness there cannot be denied, he has never in his life had to worry about a strike coming from anywhere other than someone’s fists. Mayweather facing the likes of McGregor, in a cage, would put the boxing legend at an even greater disadvantage than McGregor was in when he stepped into the ring.

A far greater disadvantage.

Still, all that being said, very few thought the Mayweather-McGregor fight would be competitive, yet millions still bought it. At the end of the day whether Mayweather ever steps into the octagon with McGregor comes down to one very simple question: Does Mayweather value money, more than his undefeated record?

Because if he steps into the cage with McGregor, he will leave with one of those things.
