yankeesfan wroteis it a violation if a shot hits the rim and goes over the backboard but does not touch any support?
Under NFHS and NCAA rules, it is always a violation for the ball to pass over the backboard period. Thrown, deflected, off the rim, it doesn't matter. Passing over the backboard=violation. Of course, this is assuming the ball passes over a rectangular backboard. If it is a fan shaped backboard, then this does not apply.
