THIS. Strawweight used to be a young woman's division, but it aged out along with it's fighters. Weili, Esparza, Pennington, Hill, Jandiroba, Xiaonan Lemos, Rodriguez... All of them in the second half of their 30s. There's not a single contender in their late twenties. These hoes are aging, and not a single up and comer has been able to break through the old guard. Tatiana is the only one below 35 worth anything for the title picture. Fffs sake Jessica Andrade is younger than all of these hoes, and she's the woman with the most fights in UFC history.
The younger women are at Flyweight, and even there only Blanchfield and Barber are near title contention. The rest of them are in their thirties too.
