Rogan is not wrong here
Dustin Poirier net worth: $4 to $6 million
Conor McGregor net worth: $120 million
A clear case of talking>>> skills in making money
This is bullshit analysis.
Conor made all of that money because of his talk and backing it up. Up until the Khabib fight he was 9-1 in the UFC with 7 knockouts. His one loss was Nate, which he avenged. He was a double champ. He fought money fights (double title fight, the Nate fights, Aldo). He starched the GOAT of the FW division in mere seconds. Conor is worth $120,000,000 because he was extremely entertaining as a personality and as a fighter.
Dustin was not as accomplished as Conor up until 2016 when Conor had made all of this money. Then Conor parlayed that into the Mayweather money in 2017. Dustin had not shown that he was more skilled than Conor by this point and he had been finished by Conor.
It was in 2017 that this flipped with Conor losing to Khabib and Dustin going on a tear of good wins. Even so, Dustin isn't as entertaining as Conor was up until 2017 either in fighting or as an entertainer. Up until 2017, Dustin was 12-4 in the UFC with 8 finishes (5 KO's, 3 subs) and he certainly hadn't starched the GOAT of the division after claiming that in past centuries he would have ridden a horse into his country, conquered it, and enslaved his people.
Dustin doesn't have Conor money because he isn't Conor. Dustin is a more skilled fighter
now, but that's the recent history, not the totality of the situation.
All that being said, yeah talking > skills for money but you have to have a minimal skill level and Conor far exceeded that lol. He was the champion of 2 divisions. Even a Nate Diaz who is a journeyman far exceeds the minimal skillset necessary to make good money because of his marketing prowess.
