Displacement - Posting POE

[Jimgolf]

The offense may “shape up” to receive a pass or to force the defense to deploy or assume a legal guarding position at the side, in front or behind the offensive post player. When the offensive player then uses the “swim stroke,” pushes, pins, elbows, forearms, holds, clears with the body, or just generally demonstrates rough physical movements or tactics, that is a foul on the offensive player and must be called without warning. The defense can assume a legal, vertical stance or position on the side, front or behind the offensive post player. When the defense undercuts (initiates lower-body non-vertical contact), slaps, pushes, holds, elbows, forearms or just generally demonstrates rough, physical movements or tactics, that is a foul on the defense and must be called without warning.

When a player dislodges an opponent from an established position by pushing or “backing in”, it is a foul.

Just curious how many feel this will change their approach. If you currently give warnings in this situation, will you now just call a foul? Will you call "backing in"? Or is this the way you've been calling it all along? Or is it "we don't call it that way around here"?
