The new rule is poorly written and ambiguous. I'm not sure how the referees will interpret it and not sure if the players really know what they can and can't do during a FO. I know many here will scoff and say it is clear, but it isn't.
In one sentence the rule says, ball cannot be carried or lifted in the back of the stick. Then, to clamp the ball in the back of the stick is still legal but the ball must be moved, raked or directed immediately.
What constitutes a carry? Does the fogo have to take a step? What constitutes a lift as opposed to a clamped ball being directed? If the ball is clamped in the back of the stick and the fogo is rotating his body around the stick while forcing the ball down on the ground looking for an opportunity to direct, the ball is moving, it that illegal?
Only time will tell, but personally, the fall may be an officiating nightmare and the players have no real direction.
