Illegal Dribble?
 

A1 steals a pass and is heading toward half court. B1 cuts him off and suprises A1. A1 realizing he is running out of Real Estate leaves the ball and involuntarily goes out of bounds. A) He establishes inbound status and picks up the ball b) continues the dribble c) Starts a new dribble.

Looking at 9-5

SECTION 5 ILLEGAL DRIBBLE
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.
PENALTY: (Section 5) The ball is dead when the violation occurs and is
awarded to the opponents for a throw-in from the designated out-of-bounds
spot nearest the violation.

And the case book example..

4.15.4 SITUATION D: While dribbling: (a) A1 bats the ball over the head of an
opponent, runs around the opponent, bats the ball to the floor and continues to
dribble; (b) the ball bounces away but A1 is able to get to it and continues to dribble;
(c) the ball hits A1’s foot and bounces away but A1 is able to overtake and
pick it up; or (d) A1 fumbles the ball in ending the dribble so that A1 must run to
recover it. RULING: Violation in (a), because the ball was touched twice by A1’s hand(s) during a dribble, before it touched the floor. In (b), even though the dribble
was interrupted it has not ended and A1 may continue the dribble. In (c), the
dribble ended when A1 caught the ball; and it ended in (d) when it was fumbled.
Even though the dribble has ended in (c) and (d), A1 may recover the ball but may
not dribble again. (9-5)


Which ones are violations and which ones are not.

Thanks in advance...

A. Legal.
B. Legal.
C. Not possible until A occurs. Then, it become illegal to start a new dribble.

A1's dribble doesn't end when A1 leaves the ball, it is just interrupted. A1 may resume that dribble or end that dribble legally as long as they are inbounds when they do so.

If A1 is able to leave the ball with B1 so close and still be able to return inbounds and get get the ball, B1 doesn't deserve the benefit of the violation.

Let's Take Advantage Of A Teachable Moment ...
 

To expound upon Camron Rust's excellent answer, just a few friendly off season reminders: There is no player control during an interrupted dribble. A player control foul cannot be charged during an interrupted dribble. A time out request may not be granted during an interrupted dribble. A closely guarded count should not be started, and if one has already been started, the count should be terminated during an interrupted dribble. The player involved with the interrupted dribble cannot be called for an out of bounds violation. Team control continues during an interrupted dribble. A team control foul can be called during an interrupted dribble. A three second violation can be called during an interrupted dribble.

(Did I cover all of them? Will this help my chances of becoming an esteemed Forum member?)

Considering the section heading, it seems that the illegal action listed in article 3 makes your above statement false.


RULE 9
SECTION 3 OUT OF BOUNDS
ART. 1 . . . A player shall not cause the ball to go out of bounds.
NOTE: The dribbler has committed a violation if he/she steps on or outside a boundary, even though he/she is not touching the ball while he/she is out of bounds.
ART. 2 . . . No player shall be out of bounds when he/she touches or is touched
by the ball after it has been released on a throw-in pass.
ART. 3 . . . A player shall not leave the court for an unauthorized reason.

Poker Face ...
 

I call your 9-3-3 and raise you a 4-15-6-D: During an interrupted dribble: Out-of-bounds violation does not apply on the player involved in the interrupted dribble.

(If I'm wrong, I hope that it doesn't disqualify me from becoming an esteemed Forum member.)

OP says he left "involuntarily." That's not a violation of 9-3-3.

Actually, the player involved in an interrupted dribble can be called for an OOB violation under Art. 1 by touching the ball while OOB. It is only the NOTE that they are not subject to violating.

I can agree with that.

Dribbleus Interruptus ...
 

Once he touches the ball the dribble is no longer interrupted, and all bets are off.

Just A Regular Dribble, Not Interrupted, Friendly Reminder ...
 

9-3-1-Note: The dribbler has committed a violation if he/she steps on or outside a boundary, even though he/she is not touching the ball while he/she is out of bounds.

Not true. A dribble is an action done by a player in control of the ball. If the dribbler loses control and then touches the ball once or more in an attempt to regain control, that player is not dribbling again and the dribble is still interrupted.

Agree. It might hit the dribbler-interrupted's leg or something in a way that is not a dribble.

Or even his hand as he slaps at the ball attempting to regain control.

I'm having trouble seeing how someone would involuntarily leave the floor from the play described.

Especially since he realized he was running out of real estate...this would seem to me to be exactly why you would voluntarily leave the inbounds.

Trying to stop. Slight bump knocks him off course. He merely steps on the line.
