Why not, if the back of the ball is there? 1D: A1's run ends with the ball being held with its long axis parallel to the yard lines, and the entire ball just barely out of the end zone. When you ready it for play for 2D, you put its nose at the foremost point when the runner's progress was stopped, resulting in its tail's being behind the goal line. Unless you're following Brice Durbin's instruction to always (unless it's a safety, of course) make the spot have enough room to put the ball entirely outside the end zone, no matter how it was positioned when it became dead.
