As the second half of the NFL season gets underway, there will be teams that separate themselves from the rest of the pack and there will be those who stumble along while they try to stay relevant.
For these 10 coaches, next week is never guaranteed and every loss in the standings leaves their jobs in question.
In the competitive world of professional football, a winning team is a profitable team. As a coach, if you win games, you bring in revenue. But that isn't always the case.
With high expectations and very difficult standards to meet, no coach is safe anymore. Here are 10 NFL coaches who are on the hot seat.
After a surprising 6-10 season filled with memorable moments from Cam Newton in 2011, the Carolina Panthers were supposed to make some real noise in the NFC in 2012.
So far, the only noise has been from Newton's constant whining.
It took the Panthers nine weeks to pick up their second win of the season, five of their six losses have been by six points or less.
Carolina is staying competitive in most of its games and the team has improved over the last couple of weeks. But the fact of the matter is that the Panthers still only have two wins.
And the second half of their schedule doesn't exactly get any easier.
After starting 4-0, the Arizona Cardinals have found themselves riding an ugly five-game losing streak. Three of those five losses have been by 14 points or more, and they even managed to lose to the Buffalo Bills at home along the way.
The Cardinals have been without consistent quarterback play all season and it's finally taking its toll on the rest of the team.
Arizona is 23rd in the league in passing and 31st in rushing. Ken Wisenhunt's team has been burned by injuries all year long and the healthy Cardinals just don't seem to be showing up anymore.
Rex Ryan is definitely a love him/hate him kind of guy. He consistently runs his mouth to the point of no return, yet somehow manages a way to silence his critics.
But sometimes he crashes and burns miserably. With all of the controversy surrounding quarterback Mark Sanchez, Ryan has found a way to assure his quarterback the job is his. At least for now.
The New York Jets' offense is horrible and Sanchez's struggles can be connected to the fact that his No. 1 receiver is Jeremy Kerley. Nothing against Kerley, but he's not exactly Calvin Johnson.
Ryan enjoyed early success as head coach of the Jets by reaching the AFC championship game in back-to-back seasons. But the time has come for him to finally deliver and put his money where his mouth is.
After an impressive start, the Washington Redskins have been one of the most disappointing teams in the NFL over the last two weeks.
They suffered an ugly home loss to the Pittsburgh Steelers in Week 8 and were manhandled by the Carolina Panthers the following Sunday. Not to mention rookie sensation Robert Griffin III has digressed as of late.
Mike Shanahan's team got off to a surprising start but now the Redskins are in the midst of a three-game losing streak right before heading into a whole bunch of tough divisional games.
Despite the Redskins' fast-paced offense, opposing teams are making a mockery of their defense by throwing for an average of over 310 yards per game.
With each loss comes more uncertainty as to whether Shanahan really has what it takes to lead this young team to greatness.
Mike Munchak's Tennessee Titans were absolutely humiliated at home by the Chicago Bears by a final score of 51-20 in Week 9.
After going 9-7 in his first season as head coach, Munchak's team has greatly underperformed this season. The Titans have given up 30 points in seven of their nine games this season.
Tennessee's defense at this point is about as horrible as the New Orleans Saints and the Buffalo Bills. And despite having Chris Johnson in their backfield, the Titans are only 25th in the league in rushing.
With the exception of two meetings with the Jacksonville Jaguars, the remainder of the Titans' schedule is very challenging. They still have to travel to a much-improved Indianapolis team as well as Lambeau Field to take on the Green Bay Packers.
Not to mention they still have one more matchup with the Houston Texans in between. Needless to say, it will be rather difficult for the Titans to salvage six wins this season.
When you're the head coach of the most popular team in the NFL under the league's most egotistical owner, you are expected to win. And win a lot.
So far, Jason Garrett's Dallas Cowboys seem to have done everything in their power not to win. They've been hot and cold all season long and Garrett's job is on the line because of it.. One week the Cowboys are upsetting the New York Giants, the next week they get blown out by Seattle.
Garrett is riding a roller coaster of mediocrity in Dallas and Jerry Jones is not happy. Much like the Oakland Raiders, Dallas consistently finds a way to lose games.
Tony Romo is throwing interceptions at a ridiculous rate this year and Garrett will ultimately have to take the fall for his quarterback's erratic decisions.
In a dangerously competitive NFC, the Cowboys playoff chances are dwindling with every second they mismanage on the football field.
So how about all that money Buffalo spent in the offseason? No, seriously. Somebody tell me where that money went because this team is absolutely horrible.
After losing eight of their final nine games last year, the Buffalo Bills were supposed to be one of the "sexy" picks in the AFC this season.
Their defense has been downright laughable in every sense of the word. Buffalo is giving up nearly 250 yards a game through the air and is dead-last in the league against the run.
Ryan Fitzpatrick hasn't come anywhere close to earning the overwhelming amount of money the Bills are paying him as the team is 29th in the league in passing offense. If not for Fred Jackson and C.J. Spiller bailing Fitzpatrick out, who knows where this offense would be right now.
Chan Gailey only notched 10 wins in his first two years as head coach in Buffalo and hasn't proven he's worthy of staying on for much longer. His fate was pretty much sealed when the Bills gave up a combined 97 points to New England and San Francisco earlier in the season.
Some people make better coordinators than they do head coaches. Norv Turner is one of those guys. As we head into Week 10, the San Diego Chargers continue to be unpredictable and disappointing as Turner tries to save face for the rest of the season.
In 14 years as a head coach in the NFL, Turner has only had three seasons where he managed at least 10 wins. The Chargers haven't made the postseason since 2009 and haven't played like a playoff-caliber team this season either.
According to former San Diego Charger running back and current NFL Network employee LaDanian Tomlinson, (via NFL.com) Turner will be fired if the Chargers don't make the playoffs this season.
If Marty Schottenheimer got fired in San Diego after going 14-2, there's no way Turner should still have a job next year.
Just when you think you've seen the worst of the Kansas City Chiefs, they manage to blow your mind with another horrible performance the next week.
The Chiefs are without a doubt the worst team in the NFL and Romeo Crennel will be out the door soon enough. After leading the Chiefs to a victory over then-undefeated Green Bay toward the end of last season, Crennel got respect from around the league and secured the head coaching job for 2012.
Now, he has proven to be one of those guys who was just meant to be a coordinator.
Kansas City came into 2012 with high expectations but shortly after the season started they showed that the only thing expected out of them is disappointment. As week 10 approaches, the Kansas City Chiefs still have not held a lead in any game this season.
Kansas City parted ways with Todd Haley toward the end of last year. I don't see Crennel's situation being any different.
Andy Reid has been on the hot seat for quite some time now and he knows it. His unexpected firing of defensive coordinator Juan Castillo was a desperation attempt to save his job.
But after an embarrassing 30-17 loss at home to the Atlanta Falcons, Reid got a hard dose of reality and realized his days in Philadelphia are numbered.
In a city that loved and hated Donvan McNabb with every throw he made, Reid has found himself without job security for the first time since being the head coach of the Philadelphia Eagles.
To be fair, Reid can't be blamed for Michael Vick's turnover problems which have been the main reason for Philly's rough start. But as the head coach you are always the first one to go. Fans pay to see Michael Vick, not Andy Reid.
Unless the Eagles make a serious postseason run in an extremely competitive NFC, the marriage between Philadelphia and Andy Reid will finally come to an end.
