For one, 3A East region finalist River Hill moved down to the 2A classification along with Glenelg, Wilde Lake and Hammond. They’ll join Marriotts Ridge, which has made the 2A West final the last two seasons, and Oakland Mills in 2A South, Section I. As for the other five county teams — Reservoir, Atholton, Mt. Hebron, Centennial and Long Reach — they’ll compete in Section I of the 3A East region after being scattered across both sections a year ago. Howard will remain in 4A North, where it won a region title in 2017.
