Throw in issues HS Rules

[geoff.mayfield]

After a made bucket the inbounding team (A) can clearly pass the ball along the end line to alternate teammates to complete the throw in. A1 passes along the end line to A2 who completes the throw in to A3. But....

(1) A2 completely misses the pass and the ball remains behind the endline and rolls into the corner of the gym. Can team A call timeout (in the absence of player control by any A team mates) during the "loose ball" that occurs after the errant pass in order to avoid a 5 second violation.

(2) A1's pass is poorly thrown and the ball travels over the endline (into the playing area) and over the sideline, out of bounds into the stands. The ball is untouched until it lands in stands behind the side line.

(3) After team B's bucket, A1 (the inbounder) takes the ball and jogs towards the sideline (while out of bounds behind the endline). As he jogs, he "passes" the ball to the wall of the gym (behind the endline, imagine small gym confines--ball never enter playing area prior to hitting the wall) causing the ball to bounce of of the wall: (A) and returning to A1 whereby A1 completes the throw in to A2; or (2) whereby the ball enters the playing area and is secured by A2. Violation?
