2 shots or 1

[ChuckElias]

Well, my D1 buddy basically gave me the same answer I gave you: "I want to score the basket, but I don't know if that's really supported by rule." So I don't have any better information to share with you.

So, here's my best guess. In a HS game, I would wave off the shot, since (as it was pointed out by Mark) HS rules allow a period to end with the violation if the clock can't be stopped before the horn sounds.

In NCAA, I would award the basket and tell the irate coach that my whistle was definitely before the horn, so he's allowed to finish the throwing motion.

By the way, this is post 5,000 for me. Sorry it wasn't more helpful.
