AAU? I'll move them off the scorer's table for the throwin, too.

This whole situation has never been precisely clear to me. It seems that there is a difference between the imposition of an imaginary line by the administering official and a physical restraining line painted on the court.

In the first case, the case book play clearly says that the inbounds space between the imaginary line and the OOB line can be legally used. In the second case the 1-2-2 along with reference to 7-6-4 make the case that this area is off limits until the ball has crossed over the restraining line.

So my question is should the two cases really be treated differently in practice?
