I disagree with your answer for #57. While the ball is in the air on a jump ball to start the game,A-2 intentionally fouls B-2. Official instructs the scorer to set the arrow toward team A's basket when the ball is at the dispoal of B-2 for the first free throw. Is the official correct?
Casebook play 6.4.1SitE(c): During the jump ball to start the game,after the ball is tossed A1 intentionally fouls B1. When is the possession arrow set?
RULING: The arrow is pointed in the direction of A's basket when a player of B has the ball or it is at the thrower's disposal for the throw-in following the free throws.

I have other answers I disagree with and I am working on them.
