Go back and reread NFHS situation 1. It is telling you where to take the ball OOB, it has nothing to do with the designated spot. It says that based on where the foul happened that you take it to the endline in cases b & d, in a & c you take it to the sideline.

Kelvin,
Yeah, I read it many times and I see that implication.
But, not once have I questioned the "designated spot" and it's prohibitions.
I question the variances between Designated spot and the running throw-in. All the differences are noted, but not the presumed variable for the foot over the spot.

I do not see where an end line thrower may go back to the wall, but a designated spot thrower does, by rule, have no depth limitation. Since it is specific to one, is it automatically specific to the other?
If the depth limitation applies to both, then why does the foot over the throw-in boundary not apply to both?
