30+ years in this business and I have never heard the argument put forth here. (not even from the one guy in every association that comes up with the weekly "what if" questions)

Either we're all incredibly ignorant or someone is just sabre rattling.

You can't understand it because you're the one mistaken in your interpretation.

There's no need to change NF: 2-39. The restriction of a 1 second pause prior to a snap, relates only to player movement occurring during the 1 second immediatly preceeding a snap. There is no 1 second pause requirement between any player movements OTHER THAN player movement immediately preceeding the snap.

The fact that the application of this requirement seems clear, as written, to a majority of students of the rules, renders your suggestion for a required clarification as unnecessary.

Oh. I never thought of that.:o

In my mind I'd "rewritten" the rule to say only that a shift must end at least 1 sec. before the snap. I hadn't considered that just because a particular shift ended a given time before the snap doesn't mean all players were stationary for any particular portion of that time. I was thinking only about the second immediately before the snap, and failed to see that the failure to all be stationary for a second could require looking at an interval farther back in time.
There isn't one.

Until now I'd always thought people who didn't understand the pre-snap motion & shift rules were overcomplicating things in their minds, and that at least I could keep them straight. Now I wound up in their category!
