He Rousey'd himself. When you act like Connor McGregor, there is only one place to end up... Completely humbled and looking like a loser when somebody better inevitably comes along and kicks your ass.

Thats where the line is between the greats and the flash in the pans like McGregor who come in, make a shit load of money, big note themselves, deliver for a while then get beaten like a bitch and fade into obscurity. The greats take losses and go on to conquer bigger mountains, they grow and improve. They don't really tend to win a few fights then disappear for a few years, not bothering to fight and showing up periodically to go all WWE, walk like a noodle, talk about how great they are while spouting moronic one liners then disappearing again.

McGregor went full Rousey.
