Free throw fashions

[Rick Durkee]

An official at our intepretation meeting this morning offered this strange (and I admit, unlikely) scenario. End of the game, and a poor free throw shooter goes to the line. His shirt is untucked and he refuses to tuck it in. We are suppose to send him off, but that might give his team an advantage by being able to replace him with a better free throw shooter. How would we handle that? Do we have options?

This sounds like something that somebody on this board might have already thought up. If it is old news, I apologize, but I don't remember it.
