Try this one. Team B up 1, 3 seconds left, Team A inbounding. Being the good ref you are, you maintain your own count at this point in the game.

Time expires and horn goes off with shot in air, shot misses, all players save one under the boards are turning away (Team B is celebrating, Team A dejected). A1 taps rebound in and is also dejected, knowing hte game is over. With tap falling through basket, you blow whistle ending game by your count. Is the basket good?
