What's the matter with you guys, don't you ever actually
read 
the rule books you are given? Just kidding!
I think the basis for the disagreement on this call is a difference in the rules between ASA (and several others) and NFHS, and a difference in how the interference rules are applied at the upper JO ages v the younger.
NFHS defines interference as being physical or verbal.
ASA includes visual distraction in POE 32.
Whether a high school player should be distracted by a runner crossing between her and the ball is another matter.
