till the final minute, any team is still in the game
a 17 point deficit can become an 11 point deficit on two possessions.
I've seen Duke WIN a game in which at the 1 minute mark they were down by 10.
Plus, one minute of action won't teach anyone anything. Nor will it send a message to those coming off the floor.
The best lesson is letting those who laid the turd, endure the full stench of the turd.
