Good grief, Cyborg started at 135, Rousey started at 145, now Cyborg is at 145 and Rousey is at 135. Fighters change weight divisions as they find their optimal weight. Is that really that hard to understand?
And if the only fighter at 145 with name recognition ignores the 145 division, how in the world is it supposed to get any publicity. The one thing Rousey did well, and worked her butt off on, was hyping her fights. Cyborg doesn't get that, she just wants to show up and fight. Ideally that's the way sport should work, but its never been that way in prize fighting. If Cyborg spent a tenth the time talking about other 145 pound fighters as she does about Rousey (who gets way too much press as it is) then some of those 145 pound fighters would have some name recognition, and then Cyborg could make enough fighting them that she didn't have to do the lame route of calling out smaller fighters.
Look, I don't think Rousey would do well against Cyborg (or in a rematch against Holm for what its worth); I already stated in this thread that I think Cyborg is the WMMA GOAT. And Rousey is annoying beyond belief (and Cyborg isn't the worst of it, she said GSP had bad MMA at the time he was the dominant WW champ, she said she could beat Cain - if its a question of grief with Rousey, Cyborg should get in line, GSP and Cain should have their shots first - and I suspect a lot of people would have paid to see either GSP or Cain shut her up). However, the principle of the thing is pretty clear - you can't duck someone not in your weight division, and Rousey is now a 135 pound fighter, Cyborg is a 145 pound fighter, and anyone who thinks either is ducking is talking nonsense. The fact the difference is only 5 pounds is irrelevant, its different weight divisions, and the issue is much bigger than Rousey-Cyborg. Was GSP ducking Anderson? Was Anderson ducking Jones? Was Jones ducking Cain? Was Barao ducking Aldo? Is everyone who isn't fighting at HW ducking guys who do fight at HW? Why bother with weight divisions at all if you're expected to fight across them. Its been this way long before Rousey-Cyborg, and will be this way long after both are forgotten. You're not looking at the big picture.
And actually lots of fighters said they were better than Ali - in fact, anyone who wanted a million dollar plus purse for fighting him said it, whether they thought they had a chance or not. Calling out a famous fighter in hopes of getting big money is as old as boxing itself (typically done by people who no one ever heard of for the obvious reason - they wanted whatever press they can get). He just laughed at them, and rightly so. Who cares what Joe Journeyman says, or Larry Lightweight?
I agree Cyborg doesn't get the respect she deserves, but calling out smaller fighters isn't the way to respect, its the way to lose respect. Which is why heavier champs don't do it, other than Cyborg for reasons I just don't get. Moreover, didn't you watch Holm-Rousey? It wasn't even close - Holm absolutely humiliated Rousey from start to finish. Rousey's currently number 3 at 135, basically a no-one. And has been as quiet as a doormouse ever since. Cyborg calling out the #3 fighter in a lower weight division, one that was brutalized from start to finish in her last fight, and who hasn't disrespected her or anyone else since, is over the top silly. Who calls out someone who lost that badly and pretends its supposed to be a challenge? Watch the Holm-Rousey fight, it wasn't even remotely close. Rousey isn't the big player in 135 anymore.
It made sense for Cyborg to call out Rousey half a year ago, because Rousey was disrespecting Cyborg, and was the number one fighter at 135. It makes zero sense now, because Rousey has said zip about anything (being force fed humility does that), and is a long way from being the number one fighter at 135. People act like Rousey is still the fighter to beat at 135. She's not, and she's got a long road back, which she might never make. Both Holm and Tate are way above Rousey right now. And both are smaller than Cyborg as well.
