"Flopping" used in the announcement
I agree that in your example that might not be fully listed, but it appears they are using the word to describe the types of action in their announcement. We do not have the rulebooks yet and see if they use it as apart of the rule. But even if they don't, they are clearly addressing this situation. It was not about the wording for me, it was the fact they gave examples that are bigger than a block-charge play which people only seemed to focus on. And then they were so adamant they would T up a player for doing that, but never considered things like falling on shots or "head bob" actions that are also considered flops at other levels before this new rule change.
