If he gets hired, we'll know as soon as it happens through the media with a wink wink type of report. Won't technically be official or officially announced before the game.

Yep. Seems like every year when watching the SB the commentators are talking about the game’s coordinators and such being headed elsewhere.

Same with us last year with Kubiak.

We’ll definitely know. “League source” a.k.a. his agent will let the world know of his client’s big win.
