Hypothetical: If Moore said no, then what?

Prohibits the team from announcing. We'll know before the SB.
As soon as Moore says yes to the Saints, we'll know it within two hours. There's too many ways to leak stuff on social media, everybody in his family has a phone, someone will blab, and there are too many sports guys on social media who want to be the first to break the story.

It's possible that Moore won't decide until after the game, though. Talk about indigestion on Airline Drive...
