The problem is, she's showing that physicality against mostly low level, one step above hobbyist fighters who probably aren't in as good shape as the more dedicated fighters at the top of the BW division. Even her best opponent Coenen isn't known as being physically strong and was also being overpowered by Carmouche.
You didn't say she was unbeatable but you said she would most likely crush Ronda and you'd fear for Holm and Tate against her so who do you think would have a decent chance of beating her? If no one around has much of a chance isn't she 'near unbeatable' against current competition as I wrote? Also that 'fearing for their career and safety' kind of comment is really exaggerated considering that Coenen fought her twice and is still fighting, Tweet is still fighting, Finney who was beaten worse than anyone is still fighting etc. so it's exactly the kind of unwarranted mythologizing of Cyborg I'm talking about.
