REPLY: Hawkeye...in NCAA yes, but in Federation rules, movement by one or more to new set positions constitutes a shift.

Guys -

I could see where case play 7.2.7(b) would support an illegal shift call here, but 7-2-7 actually describes this exact situation:

REPLY: Except that in the original play, the player is no longer moving--he has stopped, but was stopped for less than the required one second. It can no longer be illegal motion in that case since he's not moving. The rule you quote presumes that the player in question is still moving.

I see what you're saying, Bob. And I know we're splitting hairs at this point, but I still think, technically, that that sentence doesn't necessarilly presume that the player has not stopped moving - it technically reads that the player either 1) hasn't stopped moving, or 2) has stopped, but for less than one full second. If it presumed what you say, it would simply read, "and has not established himself as a back by stopping."

I'm sure everyone is taking some valuable knowledge and insight away from this thread, at this point. :)

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.
