NFHS Shot Clock Guidelines ...

[Nevadaref]

Use the shot clock to administer the 10-second backcourt count (9-8).
&
Start the shot clock when:
A player inbounds legally touches or is touched by the ball on a throw-in


==============================
The above does not mesh with the current NFHS rule for ten seconds in the backcourt as a tipped or deflected throw-in pass will cause the shot clock to begin prior to the establishment of control inbounds.
