I generally sneak a peek at the shot clock, ever since I watched a playoff game a few years ago where an offical friend, working his first playoff game, called a 10-second violation with the 35-second shot clock at 27. (Insert musing comments by coach here.) At half time his partner said the shot clock had started properly, and just rolled to 28 when he hit his whistle, but the clock operator was so surprised it took over a second to stop the clock. I decided I never wanted adrenaline to cause me to have a 7-second 10-second count.
What's a 3-second violation?
