Illegal shift, or not?

[ajmc]

I think you may be misunderstanding NF:7.2.7. what is says is that a player (to be legally in motion) has to be at least 5 yards behind the LOS at the snap (only when) if he started from any position not clearly behind the line and did not (thereafter) establish himself as a back by stopping for at least one full second..."

If the ball were to be snapped before he was able to reset, establishing himself as a back, his attempted shift is illegal. If he were to be in motion having previously failed to satisfy the requirement of re-setting for a full second, (since he started out from a position not clearly behind the line) then he is illegally in motion.
