30- and 60-second time-outs

[Rich]

On the way out last night, the visiting coach (who was a very pleasant lady, even after getting beat by 45 points) asked me a question about 30-second time-outs.

She said something like: I know the players have to stay on the floor, but can the other players come off the bench and get in a circle on the court.

The only restriction I know of in NFHS ball is that there should be no on-court entertainment during the 30-second time-out. Is there anything else that was put forward nationally?

I know other officials say things like "no chairs," "players must stay on the floor," but I get the feeling all of this is hooey, myths that then become part of the rules. I told her that there was no restriction that I was aware of in high school basketball other than the warning horn is at 15 seconds and the team should be getting ready to play at the warning horn, ready to go on the second horn.

Thanks for any manual, casebook, or rulebook citations you may have.
