4-24-7 would probably apply if the offensive player contacted the defensive player by using his off-arm or hand. Do I understand the intent of that rule correctly.
AfAIK, there are no non-contact personal fouls in the rulebook, and any 4-24-7 infraction would fall into the personal foul category, because it is a live-ball offense. So, simply covering the ball using a forearm while dribbling would not be a 4-24-7 violation, if no contact is involved.
