After all these years we actually had a situation where it showed why a bag should not be used behind the line. QB was scrambling and running toward the line. Was hit from behind by a B player and the ball came loose . The U, who was directly in front of the play, threw a bag to mark the spot where the ball came loose. The R, who was trailing, and on the other side of the ball carier, came up and called it aan incomplete pass. LJ also had a fumble and was marking the spot of recovery.
