Is this common in your neck of the woods?

[Back In The Saddle]

Spot or running baseline throw-in v. time remaining on the shot clock is apples and oranges. Spot/running is not obvious. If you are the thrower and you have a brain fart and don't recall why you're throwing the ball in, there is nowhere you can look for that information. The shot clock, OTOH, is prominently displayed. Not only can the player look at any time to remind himself of the remaining time, he is coached to do so...every time the ball becomes live.

By reminding the players of the remaining time, you are doing for them what they rightly should be doing for themselves.
