I'll offer the contrary position for discussion that the guard did not receive the snap, he received a backward pass, because the snap ends when it leaves the snapper's hands.
Seems to me the intent of this editorial addition is not to allow players other than the QB to enjoy the relief of being able to get rid of a pass while under pressure to avoid injury by having to hang in there. I don't think this play falls under that type of "relief."
I know, the definition of when a snap ends doesn't help in answering the question of what about the QB who muffs the snap to the ground then gets it back and throws the pass.
I think the definition of "snap" is a bit ambiguous. Surprised?
Yes, 2-23-1-b states a snap ends when the ball leaves the snapper's hand. But, 2-23-1-a defines a snap as, "Legally snapping the ball (
a snap)
is handing or
passing it backward from its position on the ground .... " The latter clearly denotes that a snap can include a backward pass; hence, does not necessarily end when snap leaves the snapper's hands.
AR 2-23-1-I supports the concept that, if a snap becomes a backward pass, it does not end when it leaves the snapper's hands.
"Fourth and goal on Team B’s five-yard line. A55’s legal snap is muffed
by A12 and (a) any player of Team A recovers and advances the ball into
the end zone, or (b) a player of Team B recovers and advances the ball.
RULING: The
snap is a backward pass and may be advanced by any
player. (a) Touchdown. Since this is a backward pass and not a fumble
there is no restriction on a Team A player recovering and advancing the
ball. (b) Ball continues in play."
