Conor McGregor

Conor McGregor generated over $100 million in pay-per-view revenue in 2021 alone, yet his career is defined by shocking acts that transcend sports. Throwing a dolly through a bus window in 2018 injured two fellow fighters and resulted in a $50,000 fine, while a 2022 assault on an elderly pub owner in Dublin drew global condemnation—and was only settled out of court for an undisclosed sum. Compared to #1 Armstrong's organized doping, McGregor's controversies are chaotic and impulsive: he has faced three allegations of sexual assault without conviction, yet his fighting skills—a 22-second knockout of José Aldo in 2015—kept him the UFC's biggest draw. His 13-fight UFC win streak remains a record, but his legal troubles have cost him sponsorships worth millions, making him the most polarizing figure in combat sports today.
