People win fights, people lose fights. Most of the top stars in MMA have imperfect records. Her mistake is forgetting that this is actually an entertainment franchise. People want to chill out and watch good fights. Look at Conor McGregor - he's a comedian and he makes it all entertaining. He lost but you got the sense that it wasn't going to ruin his life. There seems like a sense of fun even when he's arguing with people. Ronda Rousey is just a stressed out drama queen. It actually stresses me out to watch her. Who wants to watch that, seriously? Her mistake is ultimately losing all sense of perspective and becoming completely unrelatable on any level. It is that, and not losing fights, which will ultimately have destroyed her star power.
