Reports are that the Wilfs (Viking majority owner) were not pleased with the decision to waive Moss, especially considering what they now lose (pick + salary). Sounds like Childress knew the decision could put his job at risk, but told his players he felt it needed to be done in their short & long term interest. Not the first time he's made such a move (past Christmas eve dismissal of Marcus Robinson caught him heat as well).
An informal local poll shows 80% in favor of firing Childress immediately, and another 12% at the end of the season. Personally, I think he's only an okay coach, but not the guy to take the team to a title. In my opinion, promote Frazier to head coach (about time they promote a talented coordinator rather than let them go - Dungy, Billick, Tomlin anyone?) and let Childress go.
