charge/flop?

[Troward]

NFHS:
When was the last time you made a player control call when the defender did not fall to the floor?
I'm not talking about obvious pushing off or clear outs, but it seems officials in my area Officials are requiring the defender to "fall" in order to get the call in a block/charge scenario. If the defender gets plowed into and just stumbles backwards the call seems to always go block or a no call. And then we wonder why kids are flopping so much? What are other officials seeing?
