To me I think it's common sense really. Cyborg was never going to get a top three or even top five fighter on her debut bout, at a catchweight. Like many have said it only benefits Cyborg. If she wins in dominant fashion, and fights at 135 afterwards, then yeah I could see it, but right now there's not much of an upside in fighting Cyborg, other than this preconceived notion that you get bragging rights in beating her. I'd rather fight someone in my division and get the title back, not fuck around with someone who can't even get into the weightclass.
