My guess is it's exactly what Chapin is going through this year, what Brookland-Cayce went through last year, and what Fort Mill, Greenwood, T.L. Hanna, Lexington, Summerville, West Ashley, and West Florence have experienced in recent years!
In high school soccer, save Bishop England, Irmo, Wando, and a few select others, it is impossible to maintain the top status when a team is faced with an abundance of underclassmen.
The real test becomes who can survive this downward trend for 1-2 years and rebound for another great run! It remains to be seen, but of those teams mentioned several are on the up again!
