I know we have gone over this sitch earlier on this forum, but I have asked my rules interpreter of my local assoc. and he swears this IS NOT correct. The official should change the AP after the throw-in. I have read every post on this topic and I need proof positive info to show him. I have shown him all the post and he still disagrees. Any help? Held ball.
Possession arrow is pointing toward Team A's basket.
Official hands the ball to A1 for the throw-in.
B1 reaches across the end-line as he is trying to defend the throw-in.
Official blows whistle and warns Team B for crossing the vertical plane on the throw-in. The warning is recorded in the score book.
Official starts the throw-in again.
Throw-in is completed.

Official does NOT change the Possession arrow.
Is the official correct
------------------------------------------------------------

I see no reason not to give B the arrow. Is it a note or casebook play I've missed?
