[Discuss Thrower]

Here's how the decision flowchart should flow:

+) Does the offensive player have clear possession of the ball at the point in which the ball breaks the plane of the goal line?

If he had clear possession: touchdown. If not, review to see if there was a definitive moment where the offensive player neither had clear possession nor broke the plane.

+) Does the offensive player receive the ball via a pass thrown through the plane of the end zone and does he clearly have control of the ball through the point he has established himself in the end zone with the touch of both feet to the ground?

If yes: touchdown; if no: review to see if the ball was clearly not under the receiver' control at the point when both of his feet make contact with the ground of the end zone.
