I don't have my NFHS rulebook on hand, so I shamelessly ripped this off from kdf5's
post:
Rule 2, Section 13
ART. 2 . . . Responsibility for forcing the ball from the field of play across a goal line is attributed to the player who carries, snaps, passes, fumbles or kicks the ball, unless a new force is applied to either a backward pass, kick or fumble that has been grounded.
ART. 3 . . . The muffing or batting of a pass, kick or fumble in flight is not considered a new force.
