Throw-in question

[Rob1968]

7-6-2 "The thrower shall release the ball on a pass directly into the court..." and "The throw-in pass shall touch another player (inbounds or out of bounds) on the court before going out of bounds untouched."
Thus, a) when the thrower releases the ball into the court, and the ball strikes the back of the backboard, it is a violation.
Likewise, b) if the thrower could pass the ball so that it hits the face, side, top, or bottom of the backboard and then carom back to the thrower, it is a violation.
In both cases, the ball was released "into the court" but did not "touch another player (inbounds or out of bounds) before going out of bounds" -a) contacting the out of bounds, back of the backboard, or b) contacting the thrower, who is out of bounds.
So, once the ball is released on a pass by the thrower, "into the court", the next contact of the ball determines whether a violation has occurred.
The same applies to an inbounding pass that crosses the court, without touching another player, and then goes out of bounds.
