视频-防守三秒违例 防守者抬起脚 没有离开三秒区
This is an example of a Defensive 3 Seconds Violation. Defensive 3 Seconds is called when a defensive player, who is positioned inside the 16 foot key area, does not actively guard an opponent within three seconds. In order to completely clear the lane and avoid a Defensive 3 Second Violation, a player must touch the court outside the sixteen foot key area with BOTH feet. On this play, the highlighted defensive player steps outside the key with only one foot, raising his other foot several times in the air inside the key. This movement does not clear this player of the count, and a Defensive 3 Seconds Violation is called.
