Three in the Key Reset for All Offensive Players

Q: Does the “3 seconds in the key” count restart for everyone on offence after a shot is taken or just for the shooter?

A: It does suspend for all players once a teammate begins to shoot or has released the ball for a shot.  The rulebook reference related to this is:

26.1.2. Allowances must be made for a player who:

• Is in the restricted area when he or his team-mate is in the act of shooting and the ball is leaving or has just left the player's hand(s) on the shot for a field goal.
