Your knowledge of soccer is much less important than your desire to lead a team. You can have assistance from other coaches or from an assistant coach in learning and teaching the key components of the game. If you want to learn more about soccer you can do so by attending coaching clinics, working with other coaches, and soccer videos. The focus of River Forest AYSO soccer is to expose kids to the game and have fun rather than foster competition. Coaching is too time consuming.
Coaches can arrange their own practice schedule.
Typically teams have two 1 to 1.5 hour practices a week and a single game on the weekend. That is a total of about 4 hours a week. Perhaps, if two practices are too much for you, you can split the practice schedule with an assistant coach, leaving only one practice and game a week. If you cannot justify the time to be fully responsible for a team, please consider volunteering to be an assistant coach. Usually this involves one practice a week, and attendance at games as is possible.
