You're not telling the true story.
1. Ronda and Cyborg were both asked at the same time to move down to 135 lbs by the UFC, who had just bought Strikeforce. They were contemplating trash canning the 145 lb division due to it being shallow and noncompetitive.
2. Ronda agreed to drop weight and Cyborg said she could but didn't do it.
3. Ronda said she would beat Miesha and after that move back up to fight Cyborg for a super fight between champions and a chance to become a 2 division champion.
4. Ronda beat Miesha and a fight was scheduled between Cyborg and Ronda for late June/early July of that same summer.
5. Cyborg tested positive for steroids, got suspended for a year, the fight between Ronda and Cyborg didn't happen, the UFC scrapped the 145 lb division and everyone moved the fuck on except Cyborg and Ronda haters.
