i am not 100% sure, but i think sinjin is almost right. there is one exception if i remember correctly. if the ball has already moved across the line by another player, and they decide to give it to another player that hasnt and that player jumps in the backcourt, but catches the ball in the front court, but has not established his/her position in the front court. it is over and back. once again i am not 100% sure, but i believe that is how it is. maybe coach t can give us an official rule from a TSSAA rule book.
