NFHS/Leaping

[falsecut]

I hadn't called hurdling in ten years and suddenly had occassion to call it twice in one playoff game. The above is a true definition. If the defender isn't, say, kneeling or lying prone or in a similar fashion in contact with the ground, a player from the other team can't jump over them leading with their legs. Since the NFHS is always looking for safety, they don't want a ball carrier hurdling over a defender and kicking him in the head with a shoe or something like that.
