#3 Holly Holm
When Holly Holm knocked out Ronda Rousey at UFC 193, everyone assumed that Holm was going to be a dominant champion just like Rousey. Holm’s 10-0 professional record which had seven stoppage finishes backed this assumption.
For one reason or the other, it wasn’t the case. Holm suffered a defeat in her first title defence when she was submitted by Miesha Tate.

Holm never managed to bounce back properly from this defeat. She got two title shots in close intervals after this loss to Tate but failed to capitalize on both the occasions.
Although she got wins against Megan Anderson and Bethe Correia afterwards, Holm is yet to prove her worth in the UFC as a champion.
This, however, doesn’t take away anything from the fact that she was a celebrated champion in the boxing world.
