Yeah, Cyborg has the reach advantage and she would need to use that and basically keep the fight standing. The moment Ronda were to get a hold of Cyborg the fight is over. Also I think she maybe getting ready to work with Mike Dolce because she realizes 135 is the ONLY way to get into the UFC at the present.
I dunno man, Meisha Tate hung in their for what 3 (Toss > Armbar attempts?), I think someone like Cyborg and her BJJ would help her avoid such attempts on the ground. Side control is never a guarantee in MMA, I think Cyrbog is on another level than whoever Rousey has faced on the ground. I easily give the standup to Cyborg and I have the ground game about even, I really think that Rousey is no match for Cyborg, especially if Cyborg manages a good weight cut, she is bigger and stronger as well. (I would love to see Dana's tears before he goes "Tarec Saffadine" on the Belt and Division.)
