Offensive, defensive or what?

I agree with your position.More importantly(because my opinion don't mean squat),the NFHS rulebook also agrees with you.

See casebook play 10.6.2SitB-COMMENT-"When both the dribbler and the opponent are moving in exactly the same path and same direction,the player BEHIND is responsible for contact which results if the player in front slows down or stops". A "legal guarding position" is not mentioned in this call at all.

Your opinions mean squat here JR. In rule 10.6 where is there any mention of "legal guarding position" other than in the note at the end? Take the above situation with a little different twist. Player B1, anticipating a shot turns to get position for a rebound, with his back to A1.
But wait, it was only a head fake! A1 blows by the defender
on the perimeter and goes up and dunks over B1, who has not moved for the last 3 or 4 seconds. The contact sends B1 crashing to the floor. B1 never obtained "legal guarding position" by definition, but he has not moved, so this can't possibly be a blocking foul, can it? I have thought
that when one reads the definition of legal guarding position that it seems to carry more weight than it actually
does in a game situation. Comments from knowledgeable, intelligent people (and others) are welcome now.
