CASL and CSA dominate NC soccer,like CESA does in SC, just look at last falls NC state cup results. CUFC is falling on hard times at the state/R3P level, with Lake Norman making strides at the state level.

You can also look at the Fort Mill results last year and and the Manchester Tournament results to get insight and a possible answer into your NC/SC question.

Outside of CESA, SC is a house divided, and we know that a house divided does not stand. The Fort Mill Varsity has Three players from CSA, 1 CESA, 3 CUFC, and the rest Carolina Select. All of these kids are premier players regardless of which team they play on or what league they play in. That is what I like about HS Soccer, it is the kids having fun, and the best kids getting a better shot at success than just club soccer.
