#2 She left her fighting career open-ended
This was the lasting image that Ronda Rousey left of her once prolific mixed martial arts career: Being battered and on the receiving end of punches en route to a first-round TKO loss to Amanda Nunes in just 48 seconds of action. It all took place at UFC 207 in December 2016 in Las Vegas.
For both Rousey and her fans, this is an image that would not be ideal to leave as the final imprint of her legacy as a professional MMA fighter. The harsh reality is that fans tend to forget all of her accomplishments and instead latch onto this unfortunate image of a fighter who looked like a mere shell of the great persona she upheld just three years prior.
UFC president Dana White has repeatedly stated that he does not expect to see Rousey back in the Octagon. But this is combat sports, after all, where crazier things have happened, and it would not be a surprise if "Rowdy" Ronda suddenly made an MMA comeback.
