B Conference during sub for A1's fifth foul
 

I think I know the answer to this but am seeking confirmation. A1 commits his fifth foul; table buzzes the horn and notifies the officials it is his fifth foul; officials notify A coach. As soon as he understands it is A1's fifth foul, B coach calls his players to the front of his bench hoping to get a few seconds of conference. But A coach immediately sends in a substitute and doesn't want to take any of the allowed time to make this substitution. Officials tell B coach to have B team come right back on to the court. B coach argues he can take 20-30 seconds to confer with his players. I tell B coach "He [A coach] can take time to substitute but you can't be granted the time if he substitutes immediately." B coach gives me a doubting look and reluctantly sends his players back out. Was this the correct application of the rules?

Yes.

When the required substitute has reported to the table, the 30-second interval has ended and play shall resume immediately. Therefore, if the substitute reports to the table just after the disqualifying foul is called or reported, there is no 30-second interval necessary or permitted. If the required substitute reports within a few seconds of the 30 seconds permitted, play shall resume immediately. (3-3-1d; 3-3-2)

*Note the interval was reduced to 20 seconds in 2007-08.

Coach is yanking your chain to see how far he can go.

Crafty coach. Don't let him get away with it.

I'm lining them up or getting ready to administer the throw-in.....the guy's just trying to get a freebie....not in this game.
