I'm hitting this again for clarity now that I've had time to digest it.

I have to think the delay warning is best here. If the committee wants us to call this a direct T, they should change the wording to "disposal."

The official hands the ball to A1 and he sets the ball down on the floor between his legs, but he is not touching the ball, and proceeds to give hand signals to his teammates for two seconds. When he starts to bend down to pick up the ball, B1 reaches across the boundary plane and grabs the ball.

Here, I think A has possession, even he's not holding the ball.

Change it slightly: A1 takes the ball for the throwin and drops it straight down so it bounces several times. While it bounces, he makes his hand signals. Before he can grab the bouncing ball, B1 reaches over and grabs it.

I'm pretty sure I'd whistle this a T by instinct, and that I'd be right. A1 is in possession of this ball. It belongs to him until he releases the actual throwin pass. By rule, I can't find any basis to differentiate it from Nevada's 2nd situation above.

#1: delay of game violation.
#2: technical foul.
