The life and career of an NFL head coach is one filled with twists, turns and uncertainty at any corner.
Take for example New York Giants head coach Tom Coughlin.
At the beginning of the season, Coughlin's Giants were picked by many to either finish second or third in the NFC East and on the outside looking in to the postseason. Critics scoffed at the notion that Eli Manning could ever be considered elite and pointed at the Giants' many holes as reasons for why they would finish looking up at Philadelphia and Dallas.
The Giants would then start off the season with a bad loss to the cellar-dwelling Washington Redskins before bouncing back and winning six of their next seven to start the season off at 6-2 before losing four straight and falling to 6-6.
At this point, the now annual question of whether Tom Coughlin was on the hot seat in New York would start getting thrown around by the media until the Giants finished off the season with victories in three out of their last four games to win the NFC East, leading to their status today as Super Bowl champions for the second time in the last four years.
The fact that questions about Coughlin's job security always come up is a by-product of coaching a team in the top media market in the country but is also a sign of how underappreciated Tom Coughlin has been in his coaching career.
Coughlin isn't the first successful NFL head coach to be underappreciated, nor is he the last.
Here's a look at Tom and some other head coaches throughout history who's work tends to fall through the cracks in the eyes of many fans and experts.
