Conor McGregor is indisputably the biggest box office attraction in UFC history and is the first MMA star ever to make Forbes' highest-paid athletes list.
What the Notorious One wants, the Notorious One gets. UFC president Dana White wanted the Irishman to drop back down to featherweight so he could defend his title against Jose Aldo, but the 28-year-old wanted to try and win the UFC lightweight title instead.
Of course, McGregor's wishes superseded everything else and considering the company needed a big name for UFC 205 in New York, Mystic Mac was in a very powerful position.

McGregor will fight Eddie Alvarez for the UFC lightweight title at Madison Square Garden on November 12 and despite the UFC being happy with securing a huge name for the card, White doesn't believe he is the biggest name in the game.
In fact, he thinks Ronda Rousey is a far bigger star.
"By far. Not even close. By far the biggest star," White told New York hip-hop radio station Hot 97.
"Ronda Rousey is such a big star. When you go down to Brazil, they don’t care who you are. They want the Brazilian to whup your a**.
"When Ronda went down there, they cheered for Ronda over the Brazilian.
"(I’ve) Never seen that before in my life, and will probably never see it again. That’s how big Ronda Rousey is."
The numbers would suggest that White is somewhat blinded by his fondness for Rousey and there's more sentiment in his statement than logic.
Don't get us wrong, the world of mixed martial arts is huge in Brazil and the sport is almost sacred there, but is that the only gauge?
Who do you think is a bigger star: Rousey or McGregor?
