We played in a MS travel tournament recently that had a different set of clock rules than I have used. I missed the first weekend of the tournament, gave the rules to my assistant, and promptly forgot the rules were different. The clock stoppped for shooting fouls, but started when the ball was handed to the shootier for the last FT. In a 1 and 1, the clock started on 1st FT.
In our final game, and after a long day for all involved, we are down 8 and staging a comeback, when I notice a player is shooting FTs and the clock is running. I yell to trail (O1) about the clock, he lets the clock continue, lets the shot finish, we get the rebound, he stops play and comes to explain the rules to me. Except he is a little POd, and he kind of yells the explanation at me and said that he knew the rules, had been doing it all day, he had the clock, blah, blah, blah. (and this is the first time I have questioned anything all day!) I try to apologize, but he is off across the court and starting play.
We bring the ball up, and before we even get into our offense, O1 calls an illegal screen on one of my players. His call was yelled at the top of his lungs with visible anger, and he was staring at me like, "go ahead, just try to argue this." My player had not even made contact with the other player - not even a hint of contact. (When my player came out, she asked why the foul was called since the defender just ran by her, and I told her it was on me not her
)
O2 sees all of this, calls time and takes his visibly angered O1 aside for an "official's conference." Don't know what was said, but O1 made a point of talking to me next time he was near our bench and apologized for yelling at me (but not for the foul call!) And there were no more loud angry calls for the last few minutes of the game.
Oh, and we cut it to 2 with 8 seconds to play, failed to steal the inbounds, fouled, and the girl hit both ends of the 1 and 1 with 6 seconds left - lost by 4.
Why do you call time in this situation? Simply to make the game better. That's what you're there for. If you can't find that in the rules, you should be able to find it in your sense of what your purpose on the court is at all times - make it a good game.
