Is this a "pass"?
 

According to 4.31 a pass is defined "... the movement of the ball caused by a player who throws, bats or rolls the ball to another player"

Scenario : A1 has dribbled and come to a full stop. Holding the ball in the plam of one of his hands. A2 comes along and picks ball up.

Should this be considered a pass? If so on what rule?

If A2 picks the ball and puts it back into A1 hand, can A1 start a dribble?

Whether it's a pass is irrelevant. Once A2 touches the ball, A1 may once again dribble when he regains possession.

Whether you consider it a pass or not doesn't matter. Based on what you wrote player control transferred from A1 to A2 back to A1.

I got an offensive steal :)

When A1s "pass" was touched by, or touched, another player (A2) he/she may start a new dribble.

Yes of course, thank you. I should have not included the last question; it defused the real question.

Okay, I assumed you asked the first question to answer the 2nd. My answer to the question, though, is it probably isn't a pass by rule, but it doesn't matter.

I am trying to understand if Player control is ever lost at the point that A2 takes the ball from A1 hand, that is how this all started. A pass would leave TC but no PC, In this situation PC is retained continously, in my thinking

Nope, see post #3. BNR broke it down for ya.

My last question have been answered affirmatively by all.
I then side shifted to my first question and add a bit more to the original OP ; the reason why my OP was asked? BNR broke down my 2nd question. I am referring to the "transfer" of the ball between A1 and A2 and wandering if PC was ever lost, ie when A2 took the ball from A1 hand . One could think that both A1 and A2 have PC . In a pass the PC would be lost the minute the ball left A1 hand. Is this being to picky?

I see what you're getting it. I'd consider this similar to a hand-off in that regard. During the process, there is always PC even though it changes hands, as the moment it's lost by A1, A2 has it.

I'd also say you might be a little too picky here, as I can't of any ramifications for a momentary loss of PC here even if it did exist.

It is possible for both to have PC (similar to a held ball). However, in this case, I'd say that PC ended for A1 as it sounds like A2 hold sole PC for just a moment. A2 putting their hands on the ball doesn't necessarily end PC for A1. A1 must no longer be holding the ball for some amount of time.

In this case, Camron, he was dribbling it. You're right, touching it doesn't end PC unless the ball gets away from A1 on a dribble.

So, all A2 has to do is "touch" the ball in A1's hand and A1 can dribble again? If A1 uses his dribble, gets trapped and gets someone to touch the ball, he can dribble again? Is that right?

Negative coach...

Kinda, sorta, in a way.

9-5 reads:

A player shall not dribble a second time after his/her first dribble has ended, unless it is after he/she has lost control because of:
ART 1... A try for field goal.
ART 2... A touch by an opponent.
ART 3... A pass or fumble which has then touched, or been touched by, another player.

For this thread Key words would be "Lost control" and "A touch by an opponent" ; Is this correct?
