I don't really think that Nia intentionally goes out to hurt people. I think that she was poorly trained, told to basically go out with a basic set and play the monster. That's fine, but because she's so badly trained, she makes the mistake of rushing things and she has lousy technique. WWE absolutely has to take a lions share of the blame, but a lot of this is also on Nia
I don't think she takes the wrestling side of the business as seriously as she should. When you watch her, her cardio is awful, she blows up in a hurry, and that's leading to her sloppy technique. As well for a monster, her strength is terrible, just watch her on any lift or power move, she outright struggles with lifting a 100 pound opponent. Also on the charisma and selling of the business side of things her delivery on the mic is awful and isn't improving at all.
At this point would sending her back to the performance center help her? Not really unless they practice tough love and really push her and tell her that her job is at risk if she doesn't start working on her improvements. The wrestlers really have to take a big part in this too. Sane needs to go to the higher ups and outright refuse to work with her. If a group of woman go to management and say, she's too dangerous we're not comfortable with what she does, maybe things would turn around.
When I was watching Raw last night, and I watched her come out to the ring and jump on the apron, she was already blown up, her punch at Asuka from the apron was so pathetic and crappy that I laughed.
As for Alexa, I'm a big fan of hers, I think she works really hard, and she has a great story, a great presence and you can see that she's continually adding on to her set, I have no doubt that she loves what she does. However she's a big fan of Trish, and there's nothing wrong with that except like Trish, she doesn't protect herself all that well. I cringe when she takes moves and falls wide open, and I hope that she breaks that habit. Also she's so tiny that she gets overwhelmed and really rag dolled by the bigger stronger girls. Oh and as much as I've enjoyed the Cross and Bliss team, and its been fun, its time for her to go back to being what she's best at and that's a heel. Though I think there's a swerve coming there as well.
