I get that. And IFF was not called. Then chap said, "I did not say anything about when the IFR was called," - implying that it WAS called. Which, despite chap's insistence, CAN change the situation.

If the original scenario was presented on a test, but it said IFF was called... there would be nothing to discuss. The question would be easy. The DP would be obvious - and no coach with a quarter of a brain would complain.

IFF not called is the CRUX of this discussion. It brings into play the concern that the lack of call put someone at jeopardy - and if so, we must protect them. I do agree that if the runner is just wandering off base for no apparent reason (and not confused by the lack of IFF call, running, and then trying to return, or something like that), you probably still have a double play.
