Can't speak to the exclusion of Edwards from the ProspectsNation Elite 150 2020, but PN hasn't tracked all commits that have happened this year. It's been a bit inconsistent really.
Unless there has been a secret de-commit, PN hasn't marked Kateri Poole [committed July 30] as an OhSU commit (which may be the case here because Poole has removed her announcement video from her twitter).
They also haven't noted Gabrielle Elliott [Committed October 23] as a Clemson commit.
Same with Rutgers most recent commit's Sakima Walker [Committed October 27] and Chyna Cornwell [Committed October 25].
Aaliyah Edwards officially committed October 24th, so her exclusion from the Verbals of 2020 isn't surprising considering the others listed.
