I don't understand this. Why is it wrong for the UFC to want the fight at 135? They have spent considerable resources building that 135 division and if Ronda moves up in weight to fight Cyborg and loses all that money goes to waste. Ronda then stops being this unstoppable force that draws Hollywood A lister and becomes that girl who had a good run, but got stomped by a juicer. All that is left is Cyborg in a division that doesn't exist and they are back in a situation of a few years ago.
It is all very well to hate on the UFC, but hating on the UFC for making rational choices and deciding to make money off their investments, in a legitimate way, degrades the legitimacy of any warranted criticism they might garner. They have said from the very beginning they would make the fight, if Cyborg shows she can make weight, and it has been Cyborg who has said it would destroy her ability to have babies and even left the UFC to avoid the fight.
Do I think Ronda is clamouring to fight Cyborg, no, and perhaps she is a little intimidated by her, yes, but if the UFC put on that fight she would step up and fight her like anyone else. However, it isn't up to her, it up to the UFC and it doesn't make sense for the fight to happen at any weight other than 135 and that is on Cyborg. If she doesn't want to fight for the only title that matters in women's MMA she can keep fighting undersized women in Invicta for fraction of the amount of money she would make for the Ronda fight.
