Thanks to Bob in Pacifica for pointing out Michael Silver's article at Yahoo, which states Mike Nolan will be back next year, although stripped of some power. Matt Maiocco stated in his blog that "It sounds reasonable to me."
The article is interesting in that it throws out some speculation as well:
Of course, nobody knows yet if Cam Cameron is out the door in Miami. It's my understanding that he's friends with Parcells so maybe he'll stick around there. If not, he certainly has OC experience. I'm working on getting some scouting reports on Mike Martz as I really don't see him being a good fit in San Francisco. Of course, I've been wrong before.
The article also discussed the loss of power and it's potential effect:
I'm certainly curious to see how things play out in the eventual season-ending press conference. Silver reports the changes will likely be announced tomorrow, so I will definitely be tuning in.
