She's somehow managed to build a lot of upper body strength within the 135 pound limit... the question is whether Cyborg could do the same. Then again, there's the question of whether Cyborg could even cut that much weight, considering how big she is... looking it up, she's 170 pounds before she cuts down for fights. Whereas Ronda is naturally at 135, already. - I doubt Ronda would ever concede to meeting Cyborg at 145, either. Might end up like Pacquiao... lose speed while bulking up... and lose some of that incredible quickness. - Seems like any fight between the two will be a mismatch, whatever weight they're at. And one camp or the other will always be carping about having to make that weight. - Be a shame if the two never meet. Without Cyborg, it's likely that yes, Ronda will retire before meeting a fighter that can beat her.
