IFF mechanics

[jmkupka]

Understood Steve, and I wouldn't hesitate to call the IF (after the fact) if it turned out that the runners had been put in jeopardy.
FWIW, if I was PU, I probably would have signaled it.

Not making excuses :/

Thanks for the information about NCAA. I thought the "after the fact" aspect was an interpretation all rule formats (not a black and white rule in some and not NCAA).
Not doubting your call at all, but can you steer me to where 11.17 says there is a time when it's too late to call it (besides Note #2)?
