She achieved a lot, but she surely goes down in history as more of a pioneer than an actual great fighter.
Much like 90s Royce Gracie (who either submitted you or got wasted because he could only do one thing) or early 00s Tito Ortiz (who either won via TD's & top control or got wasted because he could only do one thing), Ronda (won via judo throws or got wasted) was successful at a particular point in time, but never evolved past that.
You surely can't be considered a great fighter or an all-time great if:
A - you are so one-dimensional that once people work out how to disengage from the clinch and pop you with strikes from range, your career is effectively over because you are incapable of doing anything else at all
B - you are totally unable to come back from a loss and win another fight, because you have a heart the size of a pea and were left so devastated by that one loss, ie: having a one-dimensional mentality to match a one-dimensional skillset
For me, Ronda is the female Royce. A pioneer, but not a great fighter. Joanna Champion and Nunes and Cyborg and maybe others like Shevchenko and Waterson, this is where we should look for great female fighters with more modern and evolved MMA games.
