Your post that a friend inside the AD called you with this info, really solidifies my theory on the timing, which is as follows:
-I don't think Butch can do anything to stay an extra week or lose an extra week. I think this all comes down to getting the ink dry on Gruden, and him getting whatever pieces in place (OC, DC) that he wants before the announcement is made. I think Currie wants to do it all within 48 hours, and likely less time than that. I think that you getting a phone call from someone within the AD demonstrates a significant shift in what is going on there. More people have to know to get paperwork together and other administrative duties, in order for the announcement to be made.
I think the train might really be starting to pull into the station. I don't think they would make any announcements prior to Saturday's game, but I honestly don't think the timing of this has squat to do with the current team, bowl eligibility, or Butch's record (criminal or otherwise).
