"Chesting up" to a shooting player

I have constantly heard it said that was simply good defense and he had the defensive position. Allow me to play devil's advocate for a second and ask this: isn't the defensive player, at some point in time, allowed to be moving and maintain defensive position such that a player control foul can be called on the offensive player. Now understand, the defensive player is moving. I am curious and would like to know, Thanks.

The defender may not "belly up" or use the lower part of the body or arms to cause contact outside his/her vertical plane which is a foul.

Simple as that.

I will call player control if the defender is moving back a little and still gets bumped, even if the bump is slight.

Is the defender really put at a disadvantage by this? I mean, if the bump is slight and the defender is already moving back, is this really a foul?

It may be better to force the defender to play a little defense in a sitch like this, especially since it sounds like there's no adv. or disadv.
