Playing a sport is a full year commitment with many kids playing 11 months out of 12. You don't see multiple sport athletes so much anymore. They just can't afford to do it. Among all the sports, soccer dominates in sheer volume of numbers. The Cedarburg Soccer Club begins at age five.
Many kids ultimately play for both club and school teams.
If not from coaches, then their peers. The pressure to perform comes from all directions. Kids look around and see everyone moving in a fast paced environment. The values of our society are reflected in our kids. To help kids sort out the pressure, school districts encourage their coaches to assist the student player in setting personal goals.
