The dirty secret always was that all of the universally praised NXT women's matches were endlessly practiced and walked through beforehand, which is great but wasn't preparing them for life on the main roster at all. Which is the reason why they pretty much all struggled at first since all that alleged state of the art training ended up meaning approximately jack shit at that point.
I think that's probably why all the women praise Nattie, I have a suspicion she was either told or took it upon herself to be like "OK I know what you learned down there, but here's what you really need to know now you're up here" and guided them through the maze of surviving on the main roster.
