AFAIK, there are no exact "parameters" in the rule book for this situation. However, I believe the spirit and intent is that the offense must force the action. I offer as argument the following:
- The 10 second backcourt count, 10 second free throw count, 5 second throw-in count, and the 5 second closely guarded count. Each of which is designed to force the offense to "do something" to move the game along.
- There is no specific rule that forces the defense to advance the action.
However, NFHS 10-1-5, the "actionless contest" rule lists a goodly number of both offensive team and defensive team infractions. So it could just as effectively be argued that both teams have a responsibility to keep the game moving. You could warn them both, and potentially T them both.
Call me evil, but I'd rather single out the offense. Fair or not, they have the most to lose from a T. To me, that smells like motivation.
