Meisha, Cat, Nunes, etc, etc.....I can all but guarantee you that any bantamweight on the roster would be willing to fight Cyborg at 45 with the exception of Ronda, so long as the pay day was greater than that of an average McDonald's employee. With Ronda, it is about wanting to gain every advantage possible so that she can increase the likelihood of victory as much as possible. Ronda's brand is solely built on her image as an untouchable, undefeated killer. These other competitors don't have the luxury of being a pop culture multi-millionaire celebrity and are just simply trying to put food on the table.
Even though all BW's would likely lose to Cyborg @ 45, they would atleast gain a nice payday. In the rare event they won, their stock would greatly increase by defeating the greatest female mixed martial artist of all time, not to mention the increase in admiration from the fans for simply taking a fight against such a daunting opponent (ala David vs Goliath or Dern vs Garcia). I for one, as well as the history books, respect the fighter that takes fight's when the odds are stacked against them, while the popular fad seems to be worshiping fighter(s) that only take fights when the odds are heavily stacked in their favor, almost to the point of a work.
