Bag a fumble behind LOS

[raider]

According to 10.3.1.c, a fumble behind the line is a loose ball play. And according to 10.4.2.b, the enforcement spot for a penalty on a loose ball play is always the previous spot. Makes no difference if the ball goes out of bounds or not, nor if the ball is fumbled from behind the line and rolls beyond the line. Therefore, a beanbag means nothing and should not be thrown. In fact, about the only case for a beanbag behind the LOS is when it is a passing play, and R is the only one in proximity and the QB is being driven back prior to a sack. The beanbag can be used to mark the progress spot since the wing officials are most likely downfield.
Hope that helps.
