Addazio is gone. Gunnell is the interim. Jarmond is leading a search. That's what everyone knows. This is what I've been told.
The writing was on the wall a long time ago. But things have been falling apart behind the scenes since the Kansas game. You saw testiness from the staff online and even behind closed doors (an alleged assistant fight). Addazio didn't know if he would be fired for certain, but that was the rumor going around the team after Notre Dame. BC also granted Rutgers permission to talk to Addazio, so that also sent a message.
While they could have gone in many different ways with the staff, Gunnell was a relatively safe pick. He can focus on recruiting between now and the bowl (mostly keeping verbals committed) and let the coordinators get ready for the bowl game. He is well liked by all and will be a very likely candidate to stay on with the new coach.
Lots of names have been floated by Feldman and Thamel. Most are predictable and are close to what I have heard. The only name that I think will get a real look that wasn't floated out by those two is Bret Bielema. While there have been feelers and guys who have been reached out to, nothing is even close to being done and no one has had a formal interview. That will start soon (probably later this week). Father Leahy has traditionally been a Wild Card in these events with regards to budgets and approvals, but supposedly he is truly going to let Jarmond run the show (see the wording in the press release).
The Al Washington stuff is pure gossip or speculation. Al might end up being the guy, but this wasn't predetermined and it certainly won't be decided early this week. The Al/Don Brown package is also not a thing.
If I were betting, I would predict Jeff Hafley but this process never settles on the first hot name (see Mark Whipple, Jack Bicknell Jr or Bob Diaco).
