The result of a myth?

[ref18]

I actually had a question on this topic that i was going to post later on.

But here's a great place to do it.

If the ball carrier is pushing off or holding the defender, even though the defender doesn't have legal guarding posistion, is it still a player control foul. I only thought that guarding posistion applied to block/charge rule. But a lot of coaches seem to think otherwise. I'm just wondering if i'm wrong or if they are?
