In this case not a stereotype. I think she had tremendous raw intelligence but she was a fulltime mom with kids and was caregiving for her aging parents at the same time and a husband on the road a lot. This just didn't leave her much time to deep dive on anything. If I were in her shoes I'd probably been fired for not keeping up. So she likely had the potential of being the most technically deep person on the team but her life didn't really give her much time to develop that. In the end it didn't matter for the team as a whole: she made things better because she simply was a better and more preceptive person than most people.
