SHIFT - LEGAL OR ILLEGAL?

[NVFOA_Ump]

Team A muddles for a few seconds and gets in formation with all players set but linemen are standing up.  QB looks to sideline for verbal play call from coach, then calls play.  QB A-12 starts signals and while calling signals interior linemen go to 3-point stance, while outside wide receiver A-88 who is off the line simultaneously starts in motion.  2-3 seconds later the ball is snapped while A-88 who is still in motion is directly behind QB A-12.

Illegal shift by linemen. The other 10 players have to remain set while the back is in motion. Live ball foul at the snap.

I don't see any difficulty. If more than one team A player is moving at a time, the whole team must come to a complete stop for one second before the snap.

The whole team did come to a complete stop for one second, so this is not the false start of the second kind but a live ball foul at the snap.

I don't see any difficulty.

While the crew agreed without question that we had a flag for an illegal shift, we did not agree on the live ball vs. dead ball part.  The difficulty boils down to would this AR apply to the case play?

AR 7-1-2-II. Ten Team A players shift while A1 remains stationary. A1 then starts moving backward before one second elapses and the ball is snapped.
RULING: If A1, who moved, did not halt with the other Team A players for one second before the snap, it is a dead-ball foul at the snap for a false start. Penalty—Five yards from the succeeding spot.

If I am reading the situation correctly then all players wereset at one point. The problem started when the linemen went to a stance at the same time the back went into motion

If I read this all correclty, the lineman (getting in stance) and the back (going in motion) were all moving at the same time.  Even though the linemen were set, the back never did... illegal shift, live ball.

In this AR it is not specified if the team did come to a one-second stop before the shift, so we must assume that they did not. Thus this AR cannot apply (if it did, it would contradict the rule and be invalid).

Team A muddles for a few seconds and gets in formation with all players set ...

Here's the key moment of the play: if all 11 came set before the snap, then any subsequent illegal shift would be a live-ball foul at the snap.

Only when A never comes set — as in the A.R. — would it convert to a dead-ball foul (FST).
