In regards to previous post about pre-game dunking.

3 dunks in warmups - 2 by A12 and 1 by A55.

Two player technical fouls on A12 who is now disqualified.
A player technical foul on A55.

Coach is disqualified due to 3 indirects.

Team B starts game with 6 free throws and the ball at the division line opposite table. Arrow set to Team A

All good.

Assistant Coach A takes over the helm for departed Coach A.

My questions are these:
Is Asst. Coach A now the 'head coach' for rules purposes?
Does Asst. Coach A have coaching box privileges?

What do you do if nervous, potentially unaware Asst. Coach A sends (disqualified) A12 to report to the table later in the game?
