This is an example of a Defensive 3 Seconds violation. On this play, the highlighted defensive player does not actively guard an opponent while he is positioned in the key for longer than the allotted three seconds. Note that the count starts as soon as the dribbler crosses the mid court line and there is a defender in the lane who is not within arm’s length of an opponent. Defensive 3 Seconds is called when the defensive player, who is positioned inside the 16 foot key area and not guarding the offensive player with the ball, does not either actively guard an opponent or exit the lane within three seconds.
