Strikers shouldn't play the grappling game and grappler shouldn't play the striking game. It would have been different if she had good balance of striking and grappling but she doesn't. Effective striking isn't something that someone can learn in just a few years. She had her elbows out, no head movement , no body movement, and bad guards and that was before the punches landed. Rhonda has always had bad footwork for striking and her kicks are equally horrible.
I actually felt sorry for her because it's so clear that someone didn't train her properly. I had to go back can check here 2016 training just to make sure my ego wasn't getting out of hand. Unfortunately it looks like I'm pretty spot on with the analysis. You can see the elbows pointing out in her training, along with the bad footwork (aka standing in one spot).
She actually has the same problem that one of my students has. She punches without the awareness that her head is open when she punches. By this I means she is so intent on punching that she becomes totally unaware just how close her opponents hand are to her face. In the sparring video she's punching and you can see her opponents hands all over her head.
I would have had her focus on her footwork as top priority, the next would be to train her defense for jabs, crosses, and hooks. Based on what I saw in the match she was so afraid of being hit on the side of her head that she would put that guard up before the punch was even thrown. The last thing I would have worked on would have been 1 punch and 1 kick so that she can set her opponent up for a shoot or a clinch. Rhonda's strength is in her grappling and she should have played to that strength. She would have to train at least 6 years fighting against various types of strikers until she could feel comfortable with handling punches coming in. Only then would I even factor a game plan for her to use striking. Her trainers must really hate her. lol
