The coach knows, or should know, that the official book staysat the table until the final horn and the officials have left the visual confines of the court.

A coach should know that he cannot send a player who has been replaced back into the game until after the clock has been started properly following his replacement. But when he tries to do it, you don't give him a T, you just don't let the substitute enter. I feel sure that there are coaches that don't know this rule about the book.
