Parity is running rampant throughout the NFL this season, but some teams have still failed to meet expectations.
The Dallas Cowboys were the preseason favorite of many to represent the NFC in the Super Bowl, but their 1-3 start has left those same people wondering if they will even make the playoffs this season.
Cowboys coach Wade Phillips has been on the hot seat multiple times during his tenure in Dallas, and he has found himself there once again this year.
The Cowboys have played undisciplined football this season, turning the ball over seven times and committing 28 penalties in just four games.
On paper the Cowboys are one of the league's most talented teams, but that talent has yet to translate into wins this season.
Phillips has won just one playoff game with the Cowboys, and if he fails to guide them to the postseason this year he will be out of a job.
Phillips is not the only coach who will be looking for a new job by the end of week 17, here are five more NFL coaches who's jobs are in danger.
Mike Singletary smelled a rat after the Niners week 1 debacle in Seattle, and if San Francisco doesn't pull a complete 180 starting next week, the former Bears great will find his job exterminated.
Offensive coordinator Jimmy Raye has already fallen victim to the team's struggles this season and Singletary will be next on the chopping block.
The Niners were supposed to be a lock to win the NFC West, the league's weakest division, and a dark horse contender to reach the Super Bowl, instead San Francisco is one of three remaining NFL teams without a win.
San Francisco's opening week loss at Seattle set the tone for a downward spiral from the team and they have been unable to right the ship ever since.
Quarterback Alex Smith has been inadequate for much of the season and the defense hasn't preformed up to expectations either.
The Niners have a must-win game against Oakland on Sunday and if they are unable to win then Singletary will most likely be looking for a new job.
Fox has done a solid job in Carolina during his nine year tenure with the Panthers, guiding the team to three playoff appearances and two division titles.
Fox's Panthers have always been competitive, winning at least seven games each season since 2002, but this Carolina team is a far cry from the 2008 team that went 12-4 and won the division.
There is little doubt that Fox is on the hot seat after his team's 0-5 start this season and things don't figure to improve any time soon.
Rookie quarterback Jimmy Clausen has played like a first-year starter this season after taking over for Matt Moore, completing just 47.3% of his passes this season and one touchdown.
The Panthers have the 12th ranked defense in the league but the offense has failed to produce at a level that allows the team to win. Carolina is averaging a meager 10.4 points per game this season, the lowest in the league.
Carolina's offense and the fact that they play in the NFC South, one of the NFL's toughest divisions, are major reasons why the Panthers will be looking for a new coach by the end of the year.
Gailey is probably wishing he would have stayed in college because things haven't gone so well in his return to the professional ranks.
Gailey spent the 2008 season as the Kansas City Chiefs offensive coordinator before being fired just two weeks before the start of the 2009 regular season. Gailey spent last season out of football before the Bills hired him as their new coach this season.
The 58-year old is having a rough time in his first season in Buffalo as the Bills are off to an 0-5 start and have been outscored by 74 points this year.
Buffalo is another team that has struggled to find a franchise quarterback and their fans are hoping to land one of the top signal-callers in next April's draft; it's unlikely Gailey will be around to coach him though.
Mangini's Browns struggled for most of last season before winning their final four games to finish 5-11.
Cleveland was expected to ride that wave of momentum into this season with new quarterback Jake Delhomme and a strong rushing attack led by Jerome Harrison. Things haven't gone as planned as both players have struggled with injuries and the Browns have gotten off to a 1-4 start.
The Browns are not the NFL's most talented team by any stretch but they do have enough talent to be competitive and so far they have been unable to do so under Mangini.
Another factor working against the former Belichick assistant is the presence of the team's new President Mike Holmgren.
So far Holmgren has stayed out of the coaching decisions, but if the Browns continue to slide then Mangini could find himself without a job before season's end.
Is Tom Cable going to be fired as the Raiders head coach?
Ask a Raiders fan that question and depending on the week you will get a different answer. Oakland is coming off a big home win against division rival San Diego so Cable's job is safe for now.
It doesn't figure to stay that way for the entire season though as this is still a football team devoid of talent, especially on the offensive line.
The Raiders are in a three way tie for second place in the AFC West with a 2-3 record, and as promising as last week's win over the Chargers was, a loss to win less Bay Area rival San Francisco would more than cancel that victory out.
Oakland's remaining schedule is a difficult one with two games against the division leading Chiefs, and road games at the Chargers and Steelers, as well as home games against the Dolphins and Colts.
Oakland will be lucky to finish the season with more than six wins and that will not be enough to keep Cable around for another season.
