Since Cowher has said that he wont coach this year, this leaves a pretty impressive coaching class for next offseason. Cowher will be available. Holmgren will be available (he has already said he has had 2nd thoughts about the year off, but promised his family, so he will likely be interested in coming back next year). Mike Shanahan may also be available next year depending on what happens this year. Many feel that Dungy will leave the Colts this year and that Bill Parcells will be available after this offseason or next.
As much as many people hate Herm and want him out NOW. Maybe it wouldnt be too bad to keep him for a year and see what is available next year.
Personally I am torn on the Herm issue. I hate changing coaches too often. It is very difficult for the players and every coach wants to make his mark and get rid of decent people to get "his" type of players in the organization. But, the lack of improvement in the 2nd half of the season really was disappointing and points to less than stellar coaching.
