Well if that's the case (about the ball needing to hit the rim) then the call was technically right. But it's technically right to call it every single time it happens in every game and we know that's not the case. It's also technically right to call a foul when a guy gets hammered at the end of a game (like NC State last week) and they swallow the whistles in those situations more often than not.
Just seems to me like that guy couldn't wait to make a call - and then when you compound it with the intentional foul call + the backboard call it really makes you wonder.
