Clarification on in bounds rule

[BillyMac]

A player inbounding the ball may step on, but not over the line. During a designated spot throwin, the player inbounding the ball must keep one foot on or over the three-foot wide designated spot. An inbounding player is allowed to jump or move one or both feet. A player inbounding the ball may move backward as far as the five-second time limit or space allows. If player moves outside the three-foot wide designated spot it is a violation, not travelling. In gymnasiums with limited space outside the sidelines and endlines, a defensive player may be asked to step back no more than three feet. A player inbounding the ball may bounce the ball on the out-of-bounds area prior to making a throwin. After a goal, or awarded goal, the team not credited with the score shall make the throw-in from any point outside the end line. A team retains this “run the endline” privilege if a timeout is called during the dead ball period after the goal. Any player of the team may make a direct throw-in or may pass the ball along the end line to a teammate outside the boundary line.

The defender may not break the imaginary plane during a throwin until the ball has been released on a throw-in pass. If the defender breaks the imaginary plane during a throwin before the ball has been released on a throw-in pass, the defender’s team will receive a team warning, or if the team has already been warned for one of the four delay situations, this action would result in a team technical foul. If the defender contacts the ball after breaking the imaginary plane, it is a player technical foul and a team warning will be recorded. If the defender fouls the inbounding player after breaking the imaginary plane, it is an intentional personal foul, and a team warning will be recorded.

The inbounding player does not have a plane restriction, but has five seconds to release the ball and it must come directly onto the court. The ball can always be passed into the backcourt during a throwin. This situation is not a backcourt violation.

If a player's momentum carries him or her off the court, he or she can be the first player to touch the ball after returning inbounds. That player must not have left the court voluntarily and must immediately return inbounds. That player must have something in and nothing out. It is not necessary to have both feet back inbounds. It is a violation for a player to intentionally leave the court for an unauthorized reason.
