I don't know what's going on specific to the CESA U-18 girls team but I can tell you, having had four daughters play competitive club soccer, their commitment level varies tremendously. One of them quit club soccer after U-15, two others played on competitive teams in Charlotte, but then scaled it back and played local for their U-18 season. My youngest seems to want to play at the highest level possible all the way through U-18.
Analyze the kids.......not just the club. To play R3PL or ECNL at U-18 you have to be very committed.....and if you are a player from out of the area, the commitment is even greater.
