The politics run deep. Sometimes it's easy to figure out(coach's son and friends), other times it pans out during season. Certain teams use the club as a sort of town team, where kids from the same school district as the coach get favored. Also, the coach may be friends with some of the parents and may favor those kids. For what it's worth, out of the three teams my children have played on with a coach and son, only one was a bad experience. The other two teams you would never figure out who the sons were.
