Junker wrotePossibly because there are still officials out there that use the term over the back.
I've decided not tell coaches that there's no such thing any more. The main reason, I've worked with officials who call this; officials they respect because they've seen quite a bit. Now, they are calling actual fouls, they're just reporting it as over-the-back.
So, if I were to tell a coach there's no over-the-back and my partner proceeds to call it; I'm the one who loses credibility. Now, my response is simpler. "There was no foul on that play, coach."
