We don't know. These types of Frankie Randall, Vince Phillips, Ricardo Mayorga, Holly Holms type of fighters just pop up out of nowhere and shock us.
As a fan of Boxing this shouldn't shock you that much. This was a classic bull vs matador performance, Rousey did not have the boxing skills to compete with Holly. Who's a solid female boxer.
I don't watch MMA but why don't they hype The guy that beat Silva twice. I think his name is Chris Weidman. The All American
Rousey after taking that left just stood there and got her head kicked off. NO awareness, no recovery nothing. MMA fighters usually shoot for a takedown after getting rocked or boxers try to tie up but she just stood there with her back almost to holm entirely defenseless. Is this the first time she got hit with a proper punch? Laughable. Her striking skills are non existent, she's just a glorified grappler. Not a MMA figher.
It depends on what you mean by real deal, if you're talking about someone who's at the ward, pacquiao, klitschko caliber then no one. Anyone that isn't just a hater knows GGG is very skilled, and is definitely one of the best in the sport today. But to be considered with the real "real deals" he would have to dominate that division for like 10 years like Wlad unless we see guys like Andrade, J Rock etc and other good prospects move up. 160 is such a weak division, Wlad couldn't move up, but I'm sure if he was a smaller guy he would have moved up if his division was weak. Most boxers striving for greatness MOVE UP if their division is complete dog****.
