This is very true, and it doesn't take away from Ronda's accomplishments like her white Knight supporters seem to think.
Look at Ronda's boxing in the cage, it's nothing special. She doesn't cut the cage off, there's no setup, or faints, or feeling out, just rush in swinging as girls either back themselves onto the cage, or rush in swinging for a KO and get clinched and tossed.
Slack mentions this a lot in his killing the Queen article on Rousey, but no one at BW has the skill or smarts to do it.
Something as simple as a teep when she rushes in, or a stepping elbow for her to run into when she goes for the clinch. But no, it's all swinging KO shots when they have almost no KO's.
