#4. Ronda Rousey
Ronda Rousey's fall from grace was a particularly sad one, what with the hype that she had and how abruptly it screeched to a hault. While many are quick to criticize her two losses, they came from elite fighters in Holly Holm and Amanda Nunes.

There's absolutely nothing to be ashamed of losing to these two. Furthermore, a rebound fight against Nunes showed the UFC doing 'Rowdy' no favors. She earned stardom and a fanbase through an electrifying career. From the Olympics to a 12-0 MMA career that never needed judges, Rousey put women's MMA on the map and was the star that the MMA world needed.
These accolades speak for themselves in terms of her talent. Although Rousey hasn't fought since 2016, it's not farfetched to believe that she's still actively in the gym training. As she turned her attention to other things outside of MMA following her two consecutive losses, Rousey could still be amongst the top players on the UFC roster.
#3. Paul Felder
'The Irish Dragon' is beyond a top fighter, but he's also one of the most exciting fighters to compete in the promotion. War after war, fans can't blame Felder for stepping away and taking his seat at the commentator's booth.
The 36-year-old has been on the wrong end of many controversial split-decision losses, which perhaps exacerbated his desire to compete as a professional fighter. His most recent loss was one of the few decisive ones, but a short notice bout against Rafael Dos Anjos has been proven to be a very difficult task.
While Felder also touched on personal issues playing a role in his decision to call it a career, he still has a place in the organization should he get the itch to compete again. Furthermore, he has the confidence of being the last to defeat the current lightweight champion, Charles Oliveira.
