You are right, her boxing technique is not the greatest. But technique isn't everything. For example Wanderlei is one of the GOAT and you wouldn't say his boxing is textbook either. Fighting qualities like toughness, heart and aggression count for a lot. Baszler cracked her with a hard knee in the second round and Pena just came forward like a mad man. Any fighter like that is a difficult opponent.
Raquel tends to not throw with combos, but rather single shots. She looked good against Jessamyn, but check out her fight against Smith. Smith was able to take her punches and keep firing, overwhelming Raquel. Julianna might be able to do something similar.
Jessica is still a novice at the wrestling game. If Julianna could take down Baszler I don't see why she couldn't do the same against Jessica. And Julianna's gound and pound looks extremely nasty.
Moras could probably get her down, but Julianna's already shown against Baszler that she is really hard to control and doesn't stop fighting. Baszler may of won the wrestling in the first round, but she had to constantly work hard every moment, with Julianna able to get up a oouple of times and get on top a couple of times as well. Considering that fight I don't see why are so confident Moras could beat her.
