I don't speak for her but I've read things Tate and Holm's camp have said in the past and no one seems willing to fight Cyborg at anything other than 135 lbs, unless Dana compels them to do so. That makes me wonder why. I can only assume it's the size advantage she would have, which would be someone where around 15 lbs.Ronda doesn't need you to speak for her
Ronda: "I would fight Cyborg at 140 lbs if Dana asked me to do it".
Tate: "That's my job. I have to fight anyone they put in front of me and obviously I'm not scared of anyone. So yes, I would (fight her at catchweight). But I heard Cyborg is signed to fight at 135, so I would prefer to fight her in my weight class. If they had a 125, I'd like to go down, but they don't, so it's 135 for me."
Holm's coach Winklejohn: "“Cris ‘Cyborg’ is just incredible with her strength and with what she can so”, he said. “I don’t know if she can make the weight at 135 pounds yet. She’s got a lot of holes in her game, a lot of craziness. That girl is so strong, so we’d have to be worried about it. But Holly would fight her in a heartbeat.”
I don't see anybody saying they'll move up in weight unless Dana told them to do it. In fact, Tate would move down, probably to get away from Ronda's dominance over her and Holm's coach didn't even entertain the thought of the fight happening at any weight other than 135. I guess we are all left waiting for Cyborg, like always.
