And, again, I know that legal guarding position has nothing to do with setting a legal screen. Help. Please.

We have debated this play more than once. Most recently, I think, on the NFHS Forum. The only time I see that a screen set next to a boundary line would be utilized effectively is on a throw-in after a made basket. In this case it is legal for the offensive player to be out of bounds. So how can it be illegal for him to have one foot out of bounds in the process of setting a screen? Some say it is, as I recall.
