There is some point there. The point is not for missing a field goal by the way. The point is for not allowing the opposition to take the ball out of their endzone. When you look at it this way you are not rewarding failure.
It seemed like rush ends but a step behind the LOS if my memory is meshing with yours. Also there 3 rush ends at once. Very tricky was my thoughts at the time. It seems the defense is going to be different again this year with the player movement.
