Ten or more head coaches could join Scott Linehan and Lane Kiffin in losing their jobs based on what happens over the final 13 weeks of the NFL season.
No coach is in imminent danger of losing his job during the season, but the pressure is building for Detroit's Rod Marinelli, Houston's Gary Kubiak, Cleveland's Romeo Crennel, Cincinnati's Marvin Lewis, Kansas City's Herm Edwards and, yes, the Vikings' Brad Childress.
Each has a losing record this season and a sub-.500 career mark after more than two seasons with his current team. That's not a good combination when the honeymoon for an NFL coach lasts only two years.
Four other coaches at 2-2 or 3-1 are still sitting on toasty seats.
San Francisco's Mike Nolan is at the top of that list. He's 2-2 this year, but his 18-34 mark since 2005 makes him a prime candidate to be fired.
Eric Mangini is 2-2 with the Jets, but he has Brett Favre and an offseason shopping spree to live up to. If he does, he could be coach of the year. If he doesn't, he could be fired.
Then there's John Fox in Carolina and Wade Phillips in Dallas. Both are 3-1, but Fox can't afford a third consecutive non-playoff season, and Phillips can't afford another first-round playoff exit with the league's most talented roster.
That's 10 possible head coaching changes right there. And that doesn't include situations in Seattle, where Mike Holmgren will retire and be replaced by Jim Mora Jr.; and Indianapolis, where Tony Dungy could retire and be replaced by Jim Caldwell as early as the end of this season.
