The mistake Ariel makes is the same reason he priced himself out of ESPN.
He tries to validate his own projected weight far too much. He's like the Forrest Griffin of MMA media. He made it far beyond his natural abilities should allow because he's a hard worker and made it big partly because talent was low and partly because of good fortune. And that's not a shot at Ariel or Griffin. Ariel worked his way to the face of independent MMA journalism since the beginning, which is huge, but 'independent MMA' is about his limit. Showtime and ESPN dumped him as soon as they could, and even if it was primarily Dana, it doesn't matter. He's back to his Youtube platform and that's good enough.
But this 10th 'final rebuttal' against his enemies in Schaub and Rogan is so self-destructive it's got to be ironic at this point. He spends 20 minutes every week talking about how fake and irrelevant Shaub is compared to him and that he needs to fire back. If Schaub is that irrelevant (and for the most part he is) then stop going on these tirades because he is only drawing attention to Schaub's criticisms when most people weren't even looking. He just spent half an episode retaliating in a rant so deep you would think Schaub fucked his wife or something.
I think pricing himself out of the ESPN deal has made him jaded. Attacking everyone and defending himself isn't going to work, because the people who listen to him don't really give a shit anyway, and the only thing you are doing is inviting people who don't know to go listen to Schaub to see what the beef is about.
