ARTICLE 6. INELIGIBLE RECEIVERS. All offensive players other than those identified in Article 5 above are ineligible to catch
a legal or illegal forward pass thrown from behind the line of scrimmage, including:
(d) An eligible receiver who has been out of bounds prior to or during a pass, even if he has re-established himself inbounds
with both feet or with any part of his body other than his hands.
Exception: If an eligible receiver is forced out of bounds by a foul by a defender, including illegal contact, defensive
holding, or defensive pass interference, provided he attempts to return inbounds immediately, he becomes eligible to legally
touch the pass (without prior touching by another eligible receiver or defender) as soon as he re-establishes himself
inbounds with both feet or with any part of his body other than his hands. See Article 8, Note 3.
ARTICLE 8. ILLEGAL TOUCHING OF A FORWARD PASS. It is a foul for illegal touching if a forward pass (legal or illegal)
thrown from behind the line of scrimmage:
(b) first touches or is caught by an eligible receiver who has gone out of bounds, either of his own volition or by being legally
forced out of bounds, and has re-established himself inbounds.
Penalty: Loss of down at the previous spot.
Notes:
(1) If a forward pass (legal or illegal) is caught by an ineligible offensive player, the ball remains alive.
(3) If a player touches the ball after having been out of bounds, but prior to re-establishing himself inbounds with both feet
or any part of his body other than his hands, the pass is incomplete, and there is no penalty for illegal touching.
Moore clearly was out of bounds so either he a) established himslef in bounds which would be an illegal touch or b) did not establish himself in bounds so it would be an incompete pass.
