The showdown between two-weight world champion Conor McGregor and five-weight boxing champion Floyd Mayweather in 2017 was an iconic moment. The fight was almost not important, due to the pure fact that the showdown was happening in the first place. The best in the world in boxing was meeting the best in the world in the UFC, for a $100-million-dollar dance inside of the ring.

However, since the bout happened, it feels like it's rarely been brought up. Mainly as a result of the bout not really having any consequences, there has been a lot about the rivalry between "Money" and "The Notorious" that has been lost to history.

10 The Fight Had Been Teased For Years

During Conor McGregor's rise, it felt like it was only a matter of time until he was one of the biggest athletes on the planet. As early as 2015, McGregor had teased a potential bout with Mayweather, saying that he could kill Mayweather in 30 seconds in a real fight.

That early little bit of trash talk by McGregor planted a seed for a fight that went on to become one of the biggest fights of all time.

9 Dana White Completely Dismissed The Idea At First

Dana White is not exactly the understanding type when it comes to his fighters stepping into the boxing ring. White has notably shot down the vast majority of fighters when they've attempted to crossover, and this fight was no different.

Dana White was asked of the bout in January 2017 of the bout's likelihood of happening, to which White responded that he has a better chance of backing up quarterback Tom Brady in the NFL. The fight was made a few months later, in the end, Dana didn't make an NFL roster though.

8 The Wild Press Tour

When the fight was first announced, a four-stop press tour was announced alongside it. To put it lightly, the press tour was wild.

Each stop had a different feel as they went to Los Angeles, Toronto, Brooklyn, and London. McGregor was at his absolute best, notably pulling out a 15-minute promo in the Toronto press conference that saw him go off on Showtime, the Mayweathers, and seemingly everyone.

7 Conor Had Special Clauses In His Contract

Floyd Mayweather's team really wanted to make sure that nothing crazy broke out as a result.

According to McGregor in an interview the month following the fight, he said that he would've been fined $10 million dollars had he been disqualified. Additionally, the contract had specific rules for if McGregor did something like feint a leg kick, for McGregor to be deducted points automatically rather than be warned.

6 There Was A Belt Made For The Bout

Boxing is notorious for its insane amount of belts. Most divisions have three to four champions at a time, and man fights will have a sanctioning body have a title put on the line for seemingly no reason, that was the case here.

A little-known fact is that the McGregor/Mayweather bout had a special WBC "money belt" put on the line for the fight. The bout was made of hundreds of diamonds, sapphires, and emeralds.

5 The Fight Had Closer Odds Than You'd Expect

Mayweather initially opened up as a massive betting favorite against McGregor, however as money poured in the odds switched. By the time the fight actually happened, the fight had absolutely insane odds.

Mayweather was still a -350 favorite for the fight against McGregor. However, when looking at his career, the fight had prosperous odds. Just for a quick comparison, Mayweather's previous bout against former champion Andre Berto saw Mayweather as a -3000 favorite.

4 The Fight Had The Most Bets In History

The main reason why the odds went so haywire after the betting line was first released was due to a lot of money coming in on McGregor. It wasn't just a lot for a fight either, it was a historic amount of money that came in on the Irishman.

Betting experts have since projected that the fight had the most bets ever placed on a single fight. Estimates ranged up to $85 million placed on the fight, with the majority coming in on the underdog McGregor.

3 The Fight Lived Up To The Hype

Most big boxing matches have a tendency to disappoint, especially Mayweather who was notorious for having multiple high-profile bouts that didn't live up to the hype. However, fans got the best-case scenario when McGregor and Mayweather stepped into the ring in 2017.

McGregor came out firing early, with most having him taking the first three rounds. However, after that round, Mayweather changed his game plan from his normal defensive-oriented style to walk McGregor down, which led to more fireworks. In the end, Mayweather won via a tenth-round referee stoppage.

2 The Stoppage Was Controversial

While some fans were happy to not see "The Notorious" splattered on the canvas, some didn't think he got a fair shake. Even McGregor himself was unhappy with the stoppage immediately post-fight.

McGregor was stopped in the tenth round with a standing TKO for Mayweather, it seemed that McGregor was mostly tired rather than hurt. McGregor was also never knocked down, nor got a standing-eight count, which didn't sit well with fans.

1 It Was The Second Biggest PPV Ever

While many fans knew that the fight between McGregor and Mayweather was going to be huge, however, it ended up being historically big. Despite the fight being a bit of a freakshow bout, it captured the public's imagination and it showed.

The fight wound up being the second-highest selling PPV of all time, selling 4.3 million. The fight came second only to Mayweather's bout with Manny Pacquaio, which sold 4.6 million PPV buys.
