I am not arguing. It is a d rating and it should have more to do with how well a guy defends than how likely he is to foul. A fast athletic guy that bites on every ball fake would have trouble with a slower,smarter, skilled player, but in HD there is no penalty for having a poor d rating.
I don't have as much problem with d rating being so meaningless as I once did. But it is very misleading to call that rating a defense rating.
