In the 4th qtr, when a time out is being used, either my partner or I will check on time-outs remaining at the table and inform each other and after the 2nd horn and before the ball is put in play, we will advise the coaches. We don't do this for EVERY time out in the 4th qtr...usually just once.
If we go into OT, I have my partner inform the coaches they have one additional TO, because it wasn't MY fault.
