She improved, but she is still bad. If WWE actually cared about good female wrestling she would no longer be employed. Carmella looked like a 5 star wrestler next to her.
She's not bad. She's just not good. There is space between those. If she's improved as much as she has in just a few months, and she's in the designated show to learn and improve, I think she'll be fine. NXT is still developmental. People are there to learn. You can't hold it against them when they're learning and trying to improve. If she hasn't improved at all in 6 months, then get on her case.
None of the other women in NXT started out being that good, either. Not Charlotte, not Sasha, not Becky, not Paige, not Emma, not Bayley. Eva has shown a pretty good aptitude for learning and improving, I can't imagine she's just going to stay at the level she's at. People had the same reactions to Carmella when she showed up, but she got on their good side by actually improving and putting in work.
Isn't that the match where she forgot to kick out of a pin?
No. That happened in the main event, with Becky and Charlotte.
