Who? Holm? Why do people think she would even have a slim chance beating Rousey. She's been fed stand up fighters in the minor leagues and there is nothing she has shown that would make me think she could keep off the ground and keep away from Rousey's armbar.
Cyborg has to make 135 before we start talking about that fight. Dana isnt doing a superfight for Cyborg and she has to prove she can make the weight. Once she does that then they will have no excuse but to make that fight as long as Cyborg doesnt price herself out of it.
One other issue is Zingano has had a bad run (Knee injury and husbands death). She is a real contender but still isnt ready to fight.
