Say what?
I watch a fuckton of basketball, and yes, there are about 50 moving picks a game.
I do not remember a moving pick in which the defender got up, led his shoulder into the defender's midsection, and then stood up flipping the defender over his back. That play has no relationship to a moving screen in any sense of the word. The only reason it wasn't a hip check is because it was a shoulder check instead.
