It doesn't matter who Conor McGregor fights. According to Chael Sonnen, he's the only athlete in combat sports who can truly make that claim. In this breakdown, Chael explains why McGregor's star power goes beyond opponents, rankings, and even weight classes. Drawing comparisons to legends like Mike Tyson, Oscar De La Hoya, and Floyd Mayweather Jr., Chael argues that Conor belongs in the rare category of athletes who can sell out arenas simply by showing up. But this comeback isn't just about popularity—it's about attempting something that has never been done. Chael lays out the three enormous obstacles facing McGregor. He must return from a devastating leg injury that fighters like Chris Weidman and Anderson Silva never fully overcame. He has to compete outside of his natural weight class against an elite opponent. And he must return after nearly six years away from active competition and immediately defeat a current top contender. No one has successfully done all of those things.
