He was salty about losing a fight, so he gets an immediate rematch...as the main event on the most prestigious MMA card of all time...with a fight that makes zero sense...in a weight class with no relevance....getting paid arguably the biggest purse in MMA history....
...and he retires randomly without saying why?
Man, we can do without this guy with this sort of sporadic decision making. McGregor is the one who looks the most pathetic here if his retirement hissy-fit is over pay. I don't believe it had anything to do with a media obligations as the guy loves being in front of the camera and he's never had a problem with promo stuff before.
If his retirement was over something substantial with his UFC negotiating, you'd think he - of all people - would be vocal about it. He's either so inflated with his own sense of wealth that he is basically holding the UFC for ransom to get a ridiculous pay day, or he's taken the defeat harder than we thought and is too mentally broken to risk another loss.
Either way, it's disappointing, but being at the pinnacle of the sport isn't for everyone. Look what it did to GSP - the guy was getting so stressed out about his high-profile fights that he swore he was talking to aliens.
