While 2012 has been an exciting NFL season for a few teams, it has been disappointing for others.
Arizona started off 4-0 and all was well. Philadelphia was 3-1 and the "Dream Team" was dreaming big. San Diego was 3-0 and Philip Rivers wasn't turning the ball over. Then the switch flipped.
Basically, when the season starts, each team has goals. When those goals are not reached, changes are made.
Here are head coaching changes that are destined to be made for five teams after the regular season ends on Sunday.
It has been a tremendous run in Philadelphia to say the least for Andy Reid, but it is pretty much known that he won't be with the Eagles next season.
He led the Eagles to five NFC Championship Games and one Super Bowl, but was never able to bring the Lombardi Trophy home to Philadelphia.
After putting together what some called the "Dream Team" in 2011, expectations were extremely high in Philadelphia. After finishing out the year 8-8, owner Jeffrey Lurie stated that another season like that would be "unacceptable."
If 8-8 is unacceptable, what is 4-11?
Reid will be out, but he needs to leave with dignity. He is currently the longest tenured coach in the NFL. There is just way too much talent on that Eagles team to only win four games in a season through 15 games.
Finding new employment on the sideline for another organization won't be difficult for Reid if he still wishes to coach. He has terrific credentials.
It may seem like Norv Turner has done well in San Diego, but he only made the playoffs three times in six seasons and was unable to bring home Super Bowl rings.
In 15 seasons as an NFL head coach, he has only put together five winning seasons: three with the Chargers and two with the Redskins.
He has had plenty of talent in his tenure in San Diego. We have seen LaDanian Tomlinson, Philip Rivers, Antonio Gates, Vincent Jackson, Shawne Merriman...the list goes on and on.
There was plenty of speculation that he would get fired last season, but the Chargers organization wanted to give him one more chance.
The Chargers currently sit at 6-9 and will be out of the postseason for the third consecutive year.
This Sunday will likely be Turner's last game on the Chargers sideline.
Not really too much to say here. It is just an unfortunate situation. Chan Gailey has been on the Buffalo Bills sideline for three years as the head coach and hasn't won more than six games in a season.
He is pretty much gone and seems to have accepted his fate.
He was nothing more than a mediocre college head coach during his time at Georgia Tech. He led the Yellow Jackets to six bowl games, none of which were BCS games, and only won two of them.
At the professional level, Gailey has been able to put together only one winning season in five years as head coach and is 0-for-2 in the playoffs.
Buffalo will be looking elsewhere after they play the Jets to close out their season on Sunday.
Romeo Crennel took over for Todd Haley in 2011 for the Kansas City Chiefs after he was fired. He went 2-1 in the remaining games.
In his first game as the head coach, he led his Chiefs in beating the 13-0 Green Bay Packers who were riding a 19-game winning streak. Things seemed to be looking up in Kansas City.
Through 15 games in 2012, he has managed to only match his win total from 2011. The Chiefs sit at 2-13, and with a matchup against the Broncos this Sunday, it is unlikely they will win their third game of the season.
Crennel has been a solid assistant coach for teams like the New England Patriots, but in his five full seasons as a head coach, he has only put together one winning season.
There are plenty of teams in need of a defensive coordinator that could use Crennel next season.
I think more and more people are starting to realize that the reason why Whisenhunt looked like a great coach is because he had Kurt Warner as his quarterback when his team was successful.
Once Warner retired after the 2009 season, the Cardinals hardly have been able to get anything going. The team has not made the playoffs since then, and has only won 18 games since Warner retired.
After a 4-0 start in 2012, it seemed that everything was on track for Arizona to make a surprising run at the Super Bowl.
This will be the second time in three years that the Cardinals have finished last in the NFC West.
After losing nine straight and 10-of-11, Whisenhunt is likely out in Arizona.
