5. Conor McGregor
McGregor is the most famous MMA fighter on the planet. But he’s a polarizing figure because of his dubious life choices. He has more driving citations than title defenses and has been involved in unsavory incidents. The N.A.C. suspended him for his role in the Khabib Nurmagomedov brawl in 2018.
Furthermore, he had problems with the law because of sexual assault allegations. McGregor paid off multiple lawsuits because of his alleged behavior. He constantly becomes involved in unnecessary situations that cost him thousands of dollars. In 2021, he even attempted to assault Machine Gun Kelly (via G.Q.)
