I have one question? I was holding an entry level class and a student asked about the following. One cannot be offside if they receive a ball directly from a goal kick,even if they are about 25 yards from the opponents goal, but one can be offside if there was a DFK from the 19 yard line and the opponents tried for an offside trap. A person was asking for the rationale behind it. I could only reply that the law provided for one but not the other, but not a reason why. Can you help me?USSF answer (March 7, 2007):
There is no known documentation regarding the reason for this exemption of the goal kick (or of the throw-in or corner kick). These exemptions were installed in the Laws in the 1880s. One possibility is that these exemptions have in common a method of putting the ball into play after it has passed beyond the boundary lines. In other words, a technical procedure. Another possibility is that it was an early attempt to increase goalscoring possibilities. Yet a third possibility is that it would be extremely rare for a goal to be scored directly from a goal kick, although that possibility now exists with the changes in the Laws of 1997.
