two questions

[Jeremy40]

hey guys

i am not an official, but i am a big basketball fan. i have two questions.

1. does the clock start when a player has complete possession of the ball or does it start if someone simply makes contact with the ball?

2. what is the proper way to inform the scorekeeper of a technical? do you inform the table that the player was swearing or do you just say tech. foul on #34 blue?

hope everyone understands my question.

thank you
