Defender trying to take a charge starting to fall before contact

[ballgame99]

Ahhh, the ol' "take it like a man" rule. If the player is leaning back to absorb imminent contact I am not going to hold that against them. If the leaning back (ie lack of verticality?) is what CAUSES the contact, meaning if they had stayed strait up the ballhandler would have been able to avoid the contact, then we are having a different conversation. But if an offensive player trucks a defender who has established LGP but happens to be falling back to absorb that contact I am punching it and not thinking twice.

While we are on the subject, wouldn't "ducking" (ie leaning forward and putting your head down) actually constitute a lack of verticality and create a very unsafe situation here? It really makes no sense in this rule.
