UFC’s Middleweight contender Gegard Mousasi said it best after UFC 204.

Gegard Mousasi: “McGregor is good for the sport, but uhh. But what is it?” Mousasi says about the reason for his popularity. “You had Muhammad Ali, who was a hero, great boxer. He did a lot, did big things. But now you have Mayweather and Conor McGregor “I have money! I have money!” and everybody loves it! I don’t know. That sells. People are stupid, what can I say?”
