I wish it were that way; that's the way it should be.
But my opinion/what I've seen/what I've heard and read is that if one has a particularly nasty player or players on defense, who might just be inclined to do such things anyway, then some position coaches => ^ defensive coordinators => ^ head coaches will either overlook it or just look the other way at the appropriate time.
Again IMO only the way to eliminate it is for the calls to be made when they happen and the penalties (or ejections) take place on the spot (like it wasn't in the Duke game). Hurt the team's game effort and a stop will be put to it.
