I think what a lot of people forget is that if you look at the CONTENT of Rhonda's training history, instead of just labels, she has 3 disciplines. Since they overlap, they take up 2 of the 3 dimensions in MMA. The third dimension being striking.
1. Self explanatory. But keep in mind that she trained with a lot of types of Judoka and has experience in a lot of styles of Judo.
2. Rhonda didn't wrestle on a team, but has been grappling (including stand up grappling) with wrestlers, even some high level wrestlers, for years. Including no gi grappling. And with Sambo guys too. Also there are some moves that cross over between judo and wrestling, judo even has singles.
3. Rhonda obviously gets her base for BJJ from her Judo background, and we all know that BJJ comes from Judo ground grappling. But she has trained with lots of BJJ guys, not only Diaz, and from a purely BJJ rules perspective has high level BJJ. Not the elite of women's sport BJJ, but very high level to be sure.
So Rhonda is 2 dimensional. If you can armbar everyone , you have good subs. If you can take everyone down, you are a good wrestler. Which is in theory worse than 3 dimensional. But some of the all time great of mma were (and even still are) 2D. And most of the women's division is 2 dimensional.
That said, I hope she loses. To anyone.
