Hard to say that Riverside or Wando have dropped off. Both have been in the top 4 all year long.
Mauldin seems to have a lost half a step. The 2-0 loss to TL Hanna is a changing of the guard in that rivalry. It may be TL Hanna's first win in school history over the Mauldin girls, but I don't have stats from the 90s to verify.
Wren is as good as they've ever been. Top 10 in AAAA, and on pace to tie or set their win total as a AAAA school. Burriss has his team playing as well now as at any point in the past decade.
