Bob,
I am sure that you will be able to quote this one, but I could not find it. I see that when a SCREENER is setting a screen, the screener must "stay within his/her vertical plane with a stance approximately shoulder width apart, but I could not find that requirement under legal guarding position.

As has been pointed out, a good defensive stance really requires the players feet to be outside the shoulders. Additionally, it would be impossible for a defender stay with the dribbler with this requirement since the offensive ballhandler does not have the same restriction.

But, I have already observed that you are spot on with every rule interpretation I have seen thus far.
