Dunking in warmups

[johnnyrao]

What criteria do you use to determine a dunk? In our pre-games we usually decide that if the rim doesn't shake then it was not a dunk. The player simply laid the ball over the basket and dropped it in. I have also been told by some pretty experienced officials in my area that, using this criteria, if a player lays it over the hoop it is good preventive officiating to let him know that if the rim moves it's a T. I called one one night in a freshman game after the player's second one clearly vibrated the rim and backboard. The coach said he had done it twice previous to that. I explained that on the others the rim did not move so in my opinion it was not a dunk. It worked in this instance and I think it is also a good response since the coach then knows that you were paying attention. I do not agree that looking away and pretending you didn't see it is the correct method.
