She's exactly like Wanderlei, and, with the state of WMMA being 15 years behind - that's a really good thing.
She also has a better chin than Wanderlei, and will not have too many big hitters to ever face, so she even gets away with her mistakes better than him. He was a strong, conditioned machine with a solid ground game that, combined with the S&C made him devoid of real weaknesses (aside from getting wrestled to a dec) except for that chin - which Cyborg doesn't have to worry about.
Cyborg is not the best anywhere, except perhaps physical strength, but she is strong everywhere. There is no simple way to beat her. Rousey's armbar might be the only thing, but Cyborg's not gonna get taken down easily or give the arm away easily due to Jujitsu technique and strength.
Now - paste clips of Carano taking her down...... good job. Well done....... Cyborg will not try to engage in takedowns with Rousey. People like Cyborg (and Holm) don't have to avoid the ground at all costs against lesser fighters, and sometimes end up there. Simple tactics.
