26. Khabib Nurmagomedov
Nurmagomedov is arguably the greatest UFC lightweight ever. The Russian fighter had a dominant wrestling base that overwhelmed his opponents. He also had an intense rivalry with Conor McGregor. In 2018, he defeated the Irishman but the fight didn’t end at the bell.
The Eagle climbed over the fence and jumped on McGregor’s team. This instigated a massive and chaotic brawl that shamed the sport. Afterward, the Nevada Athletic Commission suspended him for nine months. They also fined him half a million dollars (via Global News). Several other brawls broke out in the arena because of the high tension.
