Slapping Backboard on block shot attempt?

if it's the rule, then it's the rule but that would be real hard to let it go and do nothing, especially if you were sure rim vibrated while ball was contacting. D-coach could put his best leapers/slappers in and have them swing at the ball. since most shooters are below 50%, i wonder what their percentages are when shooting at a vibrating rim.

Chris, can you cite me a rule that you could call on the defense on this play? You have to let it go because it is not illegal as long as the official judges that the defender is trying to make a legitimate block. Simple as that.
