He doesn't understand that women don't fight like men, so he's using a predicated comparative analysis that will always leave him wanting.
Pena fought Pennington for the championship - they both look like shit compared to the male champs.
Valentina fought Grasso for the championship and lay n' prayed her for 5 rounds with no issue - terrible fight.
Rose fought Esparza for the title in the worst title fight of all-time.
These are the most skilled women fighters in the world and guess what? Most of them in a vacuum aren't elite at fighting when you compare them to men, they do the best they can based on the fact that women are far less athletic and have a less natural aptitude to pick ups a variety of complex fighting skills.
To him they are all terrible - Valentina, Nunes, Rose; those are some of the best female fighters of all-time. So either he just doesn't like WMMA, which is fine, or he has no understanding of how fighting works for women, which is also fine, but he should think before posting.
