Just to clarify for those posting; the ball needs to cross the plane of the goal line, which is the leading edge of the white line you see so prominantly on your screen. Not the nice darkly painted endzone, but the white line. Again, the White Line constitutes the beginning of the end zone... Now when you watch ESPN tonight, tomorrow, etc., please be sure to use your slow motion and watch the ball cross the "plane of the end zone" as previously described.
In addition, the Seattle did use the leverage from the pushoff to change direction. Both were standing flatfooted until the receiver pushed off to break on the ball.
The replay clearly shows Rothlesberger shoving the ball over the plane after he's down! And the look on his face was priceless. He KNEW!
