Indeed, I was going to touch base on the really awful way that she handled her losses blaming it on faulty mouth guards and cutting weight fatigue. That is just so lame because even if that was the case, and I don't think it is, I think she was just out-classed and had a bad strategy vs Holmes and Nunes.
There are tons of stories about how without Ronda, there might not be a women's division at all in UFC so yeah, she's pretty important. I think the enthusiasm towards the women's division is waning though, I still find Zhang and Shevchenko are exciting, but most of the others are pretty meh.
