Back In The Saddle wroteSpeaking for NFHS rules:
While one may think of this as being a POI (i.e., the intentional foul was the interruption; OOB nearest the foul would be going back to the POI), the term POI has some pretty specific connotations and is specifically defined in the rules.
Yup, it's easier if you just forget about the POI completely. The POI has got absolutely nuthin' to do with the throw-in spot for an intentional foul. It's completely irrelevant.
A throw-in going to the POI is taken to where the ball was when the interruption occurred.
The designated spot for an intentional foul throw-in is the closest spot to where the foul actually occurred.
Those spots could be 50 feet apart.
Iow, just forget about the POI.
