There is a double standard where women are judged more harshly in MMA than me. You're going on about Joanna's lack of defense because she was rocked once in a long hard fight against a worthy opponent. Her defense is great, but let's assume for a minute you're right and her defense is lacking. Almost every top fighter in the UFC has some flaws.
- Dominick Cruz has almost no power relative to his peers
- Conor has almost no BJJ game
- Jose Aldo gets wild in his striking and fades in later rounds
- Bisping's chin isn't the best, and he's criticized for having little power
- Khabib has no striking game
- Woodley gases and doesn't have high enough volume in his fights
- etc...
All of these male fighters have flaws, and they're still amazing fighters. The fact is that no fighter is perfect, but people shit all over female fighters for every little flaw and act like they're garbage. It's a stupid double standard. Fortunately, few people are like this outside of Sherdog, numbers for WMMA are great, and hence the UFC is adding another division.
