10 seconds and shot clock

[referee99]

There is no rules exception in California to use the shot clock for determining a 10-second backcourt violation. The ten seconds is determined by the trail's count, as outlined in NFHS rules.

The shot clock does start on a touch by any player, so you could very easily have the clock start and have no player control and therefore no team control and thus the ten second count does not start.

Also, the level of competency of the shot clock operators can be a factor as well as the officials' level of clock awareness.
