If I shoot the ball directly into the goalpost, and one of my team mates X is "offside," then, it could either be called offside or not called offside, depending on the situation. Offside: if my team mate is in "active" play, such as blocking the view of the goalkeeper, or blocking the goal keeper, or blocking the opponents, then it is called offside even though he is not touching the ball. Not offside: if my team mate is not in "active" play, then even though he is "offside," it is not offside. However, if the ball I shoot hits the post and comes back, then X cannot touch the ball or else it is called offside.
