Without the rule, offensive players could hover near their opponents' goal even when the play is on the other side of the field, with the hope of a long pass and an easy goal. The offside rule applies at the moment the ball is touched or passed, not when the ball is received.
A player is in an offside position if he is closer to the goal line than both the ball and the second-to-last defender, but only if he is in the opposition half of the field. Be in the opposition half. Be in front of the ball. Have fewer than two opposition players between himself and the goal line when the ball is played to him by a teammate.
