At what point to you stop the game playing and what do you tell them?

Clark,
I confess to not remembering the precise posts over the past few years that Nevadaref referred to in his post. My rule is simple.

I will allow the defensive team to make the final decision. If the offensive team wishes to move, then I will allow the defense to counter. If the defense switches that will end it.
