Please step up and volunteer! There is no such thing as a "dad" territory when it comes to sports. Plus there are never enough volunteers out there (and believe me I know, I am the age group coordinator for softball and we are always short on coaches). If you are comfortable with being a coach and you can relate well with the kids you will be a great coach. You don't even need to know the sport that great, at this age you are teaching the kids sportsmanship and a few basic skills.
