I've been trying to find some articles / analysis about DeYona's skills and type of forward she has been in high school, but not having a lot of luck. I don't think she has the same kind of build as Nneka Enemkpali or Joyner; she seems more slender and wiry, perhaps like Delisha Milton or Tiffany Jackson?
Found this article from 2016:
