The once-undefeated UFC Champion's accolades itself should be enough to convince you of her greatness. Every fighter goes through a vulnerable phase and Joanna -- despite her predictions of ending her career without a loss, has seen a predictable downfall.
Nonetheless, the queen of sprawl-and-brawl is one of the most dominant champions in UFC history. She thoroughly outstruck all her opponents while putting together an iconic title reign and has been termed as the 'Female Chuck Liddell'. No disrespect to the Iceman but Joanna is far more technically adept in the striking department as she is a certified Muay Thai Champion.
She may be a shadow of her former self but her supremacy from 2015 to 2017 with the Strawweight title helped the UFC counteract the loss of another dominant champion in Ronda Rousey.
