[Mark T. DeNucci, Sr.]

First: For a throw-in, a dead ball becomes a live ball when the ball is at the disposal of the team entitled to make the throw-in. It does not matter whether the throw-in by Team A is a designated spot throw-in or a non-designated spot throw-in. I am not doing to define "at the disposal of the throwing team" because that is not germaine to this discussion.

Second: When a Team A commits a throw-in violation, then Team A is entitled to make its designated spot throw-in from the same spot of Team A's thorw-in attempt.

In the situation in the original posting, the throw-in commited by Team A is that A1 passed the ball in such a manner that the ball did not touch or was not touched by a player on the court (inbounds or out-of-bounds). Therefore, Team B gets a designated spot throw-in at the spot of Team A's throw-in.
