mick wroteSECTION 11 SCORER’S DUTIES
Since the table crew is considered part of the officiating crew, I took care of the rest and highlighted my answer. 🙂
Maybe many officials still operate under the assumption it is their duty to inform the coaches, and perhaps many coaches still operate under the assumption that the officials have to give them this information. If it is widely done that way in your area, then, of course, you do not want to be the maverick that does it differently.
But, as Mark pointed out, having the official inform the coach is only required under NCAA rules; it is part of the scorer's duties under NFHS rules. It seems as though this falls under the same category as counting players before putting the ball in play. If a team has too many players on the court, we might be able to prevent it if we have the chance, but it is not our fault if it needs to be penalized. The same way it not our fault if a player fouls out and we didn't tell the coach that player had 4 fouls before then...
