I heard that Mike Tice and Steve Mariucci are available. If the Packers wait long enough, Dick Jauron should be on the market, too.
As a Broncos fan, I can honestly attest that Wade Philips was my least favorite head coach, but we all knew that he was keeping the seat warm for Mike Shanahan.
The few Bill fans I know feel the same way about him.
Mooch is out because Favre likely will be back in that case, and Ted E. Thompson (suuuper genius) doesn't want that. He probably would be interested in Tice and Jauron, especially if they brought in John Shoop as offensive coordinator.
Note; the preceding tells you what I think of the GM.
