Wouldn't matter. It's obvious who was first! :D

wow, thanks for those who pointed out the casebook. I remember asking this question years ago and not everyone was sure what the "real" answer was.

Fortunately, I've managed to avoid making the wrong call in these situations over the years.

Um, its actually a standing 8 count.

SECTION 5 REFEREE'S DUTIES DURING GAME
The referee shall:
ART. 1 . . . Toss the ball in the center restraining circle for all jump-ball situ-ations.
ART. 2 . . . Administer the alternating-possession throw-in to start the second, third and fourth quarters.
ART. 3 . . . Decide whether a goal shall count if the officials disagree.
ART. 4 . . . May declare the game a forfeit when conditions warrant.
ART. 5 . . . Decide matters upon which the timer and scorer disagree and correct obvious timing errors.

ART. 6 . . . Confer with the official scorer at halftime to determine the possession arrow is pointed in the proper direction to begin play in the third quarter.
ART. 7 . . . Check and approve the score at the end of each half.

Another twist on the 10 second count (as opposed to other counts) is that team control MUST be confirmed before the expiration of the count.

Before 10 secconds expires it must be in front-court team control meaning a blind heave at 9.5 buys the player nothing.

Turnover at "Heave + 0.5 seconds = throw-in at point nearest".

Not sure what you're trying to say but as soon as the pass bounces in the frontcourt (to a player or not), the count ends. The ball must gain FC status...which is done by touching the floor or a player in the FC.

You didn't mention whether you gave them a new 10. What happened?

This brings up another point. Regardless of who the "head
referee" is, if you are working with a partner that is totally incompetent, you cannot try to save the world alone. If you obviously know what you are doing and he obviously does not, the crowd and the coaches will eventually totally give up on him, and ask for/beg for/DEMAND everthing from you. Do not try to call the whole game by yourself to compensate. Your partner has to live and die with a certain amount of his own
calls/no calls.

Actually in the NBA, they only get 8 seconds.

Sorry, I posted before I read the entire thread. That'll teach me.

Sorry for taking so long to get back ...

We ended up not giving the team a new 10 seconds after the defending team said they would not guard the inbounds, and allow the team inbounding the ball catch the ball in the front court.

Thanks again for everyone's help. Happy New Year in a couple days.
