[Nevadaref]

10-3-6b While a try or tap is in flight or is touching the backboard or is in the basket or in the cylinder above the basket, intentionally slap or strike the backboard or cause the ring to vibrate.

I interpret the word intentionally in the last clause of 10-3-6b to apply to both striking the backboard and causing the ring to vibrate. Therefore, if I don't believe the player is intentionally trying to cause the ring to vibrate, I don't call the T.
Of course, I have no doubt that any slap of the backboard, intentional or not, does cause the ring to vibrate, and therefore think that it would be better if the NFHS clarified that the vibrating the ring must be intentional to be a technical foul with a case book play.
Until then, I will continue to read the rule this way.
