Had a talk in my school building this week with a Granville assistant coach. He said it is up to the discretion of the umpiring crew, and should be decided before the game. Either play it like it's a punt, or like it is a missed field goal and the defense gets the ball at the original line of scrimmage. Again, something new for me.
That is NOT even remotely true!
A field goal is a scrimmage kick, a punt is a scrimmage kick, the only difference is the use of the holder and the ability to score points. All other rules and regulations apply. All scrimmage kicks are treated the exact same once the ball crosses the expanded neutral zone.
This is an exert from a 2012 case book, this rule has not changed. And the rules from which this comes are notated at the bottom of the case study. In edition if K covering the kick downs the ball, or commits first touching, that is treated exactly as a punt, meaning that "if the ball was downed" R would take possession at the spot of the dead ball. If first touching then R would have the choice to take the ball at the spot of first touching or the result of the play when the ball became downed.
KICKS INTO R’S END ZONE – TOUCHBACK
*6.3.1 SITUATION A: A scrimmage kick by K1 comes to rest on R’s 6-yard line.
R1 attempts to recover and advance, but muffs the ball so that it rolls into the end
zone where: (a) R2 downs the ball; or (b) R3 recovers and advances out of the
end zone; or (c) K2 recovers and downs the ball in the end zone. RULING: The
ball became dead as soon as it broke the plane of R’s goal line. It is a touchback
in (a), (b) and (c). The kick had not ended because muffing does not constitute
possession, therefore, it is a kick into R’s end zone which is an automatic touchback.
The covering official should sound the whistle immediately when the ball
becomes dead as a result of breaking the goal-line plane. Force is not a factor on
kicks going into R’s end zone. R will put the ball in play, first and 10, from their
20-yard line. (2-24-2; 8-5-3a)
