Yes, most definitely, as I would classify A1 as a basketball support, an object, or another referee; think about it, as soon as B1 touches the ball, the ball is live and the clock starts.
cheers

And as soon as the ball hits PLAYER A1 standing out of bounds, the ball is dead and the clock stops and B will get the throw-in.

You're in New Zealand, so the FIBA rules might be different. Under FED and NCAA rules, A1 caused the ball to go OOB; it's B's ball.

Reminder ...
 

NFHS 7-1-1: A player is out of bounds when he/she touches the floor, or any object other than a player/person, on or outside a boundary. For location of a player in the air.
NFHS 7-1-2: The ball is out of bounds:
a. When it touches or is touched by:
1. A player who is out of bounds.
2. Any other person, the floor, or any object on or outside a boundary.
3. The supports or back of the backboard.
4. The ceiling, overhead equipment or supports.
b. When it passes over a rectangular backboard.
NFHS 7-2-1: The ball is caused to go out of bounds by the last player in bounds to touch it or be touched by it, unless the ball touches a player who is out of bounds prior to touching something out of bounds other than a player.
NFHS 7-2-2: If the ball is out of bounds because of touching or being touched by a player who is on or outside a boundary line, such player causes it to go out.

Good time for a reminder. If A1 is dribbling near the sideline, and his jersey touches a chair that's out of bounds, then A1 is out of bounds. However, if A1 is dribbling near a sideline, and his jersey touches, in turn, a coach, a cheerleader, an official, and finally, a fan, who are all out of bounds, then there is no out of bounds violation. Tricky, but still, nevertheless, true.

Maybe in FEEBLE ball, not here.

Got this from the FIBA rule book online:

23.2.2 If the ball is out-of-bounds because of touching or being touched by a player who is on or outside the boundary line, this player causes the ball to go out-of-bounds.

It's the same in FIBA rules. A1 is legally OOB, but a player anyway. Good defense by team B.

WTF :eek:

Care to make a bet on that? How much? $20, $50, $100? I'll give you 2-1 odds.
