I'm the goalkeeper for my indoor team and have never played indoors. Also, the last time I played outdoor was when I was 5!!! So i need some help. Ok, when do i have to KICK a ball that is in play? Is it just when my own team kicks it back to me? What if they head it back to me? Not a rule question, but...when should i come off the line? As soon as the opponent gets inside the box? When they are 5 ft. away? I can never figure out when to come off. Any answers will be greatly appreciated.
