So casebook play states....
Casebook 9.2.2: A1 scores a basket. After the ball goes through the net, B1 grabs it and makes a move toward the end line as though preparing to make a throw-in. However, B1 never legally steps out of bounds. B1 immediately passes the ball up the court to a fast-breaking teammate, who score a basket. RULING: Cancel Team B’s goal, throw-in violation on B1. The ball was at B1’s disposal after the made basket to make a throw-in. B1 must be out of bounds to make a legal throw-in. (7-4-3; 7-5-7).

So my question is for a situation if there was no made basket as in the above case. When do you whistle the ball dead and call the violation? After a 5 second count?
