For me I like the Claudia possibility, submission +1045 on 5D.
So in fight one between her and Joanna she got knocked down and rocked at the end of round 1. That wasn't the end of her beating as she would endure more, but endure she did. However in the second and third round she repeatedly and succesfully took Joanna down, wasn't able to finish her but proved that she could be grounded.
The bad: When Joanna fought Esparza she pretty much stuffed every TD attempted.
The good: It might be tougher getting her down this time but submission is still probably the greatest threat to her, and with Claudia's skillset not impossible.
Edit:
Claudia by ITD +620
Claudia by KO/TKO +1290
Be shocked if she knocked her out would be absurd, but ITD looks pretty solid.
