これですね（NFL Rule 2006から。新しいルールってどこかからダウンロードできます？）
Rule 7, Section 2, Article 2
Note 1: It is a Neutral Zone Infraction when a defender moves beyond the neutral
zone pri- or to the snap and is parallel to or beyond an offensive lineman, with an
unabated path to the quarterback or kicker. Even though no contact is made by a
blocker; officials are to blow their whistles immediately.
