She did very well at Paul VI. If I recall correctly, she was the leading scorer and that team included highly rated '18 post Amira Collins, Honesty Scott-Grayson, and Ashley Owusu. I think she was also the league MVP (in the highly competitive Washington Catholic Athletic Conference).
But the ranking services don't really respond to high school play that much. They are mostly based on AAU.
Just from the clips I've seen, it seems like she may need a little refinement (also noted by CoachBill and Bret McCormick) but I do think she will be very good with time.
