An advantage with turning punches over?

Yeah, I remember reading that too, YB. I also recall this, in regards to throwing the left hook:

Hi Scrap,

I'm not sure I understand what you mean by turning the fist to match the chin line. Does that mean your palm (obviously closed) is facing the floor? Or is it supposed to face yourself, so that your knuckles are all in a line vertically?

Facing the floor so the knuckles are along the Jaw line on impact, it also protects the rotator locking it giving better shoulder balance

I'm curious if the palm facing the floor offers more protection, in regards to the body's mechanics such as protecting the rotator cuff, for instance.
