10-2-1-B: Team Technical: Allow the game to develop into an actionless contest, this includes the following and similar acts: Delay the game by preventing the ball from being made promptly live or from being put in play. Penalty: Two free throws plus the ball for a division-line throw-in. Penalized when they occur.

Team B tries to inbound the ball but there are still members from team A and the coach on the court and time runs out.
