People can say duck all they want, fact is NOBODY in the top 5 should even be fighting Cyborg right now.
It's a catchweight fight, in Cyborg's debut, and probably on the prelims. Why would any fighter going for the belt do that? Let Cyborg win a fight or two, then the hype machine will be in full swing. Wasting a top five on this fight right now would be stupid IMHO. Let Cyborg win her debut, gain some fans, get some eyes on her, then the big fights come to her.
On top of that she also has known issues with making weight in the first place. Let her prove at least 140 first before even making any big contender fights.
