The holidays are usually a happy time, especially if a team is doing well, however in the NFL, the Monday after the regular season ends is when the teams that not doing so well have to start making the tough decisions. In other words, many head coaches will be losing their jobs on this 'Black Monday'.The most notable name who is already out is Washington Redskins head coach Mike Shanahan. Under Shanahan, the Redskins were just 24-41 in four seasons and the coach had a "toxic" relationship with quarterback Robert Griffin III. They only won a disappointing three games this season ending the year on Sunday with a 20-6 loss the New York Giants. Shanahan won back-to-back Super Bowls with the Broncos in 1997-98, but he has only won one playoff game since his tenure in Denver.

The second big name to lose his job is Minnesota Vikings coach Leslie Frazier, who is gone one year after taking his team to the playoffs. The Vikings lost that playoff game their record this year was a dismal 5-10-1. Frazier also had quarterback troubles and his background as a defensive coordinator came into question as the Vikings finished 31st in yards allowed. The Vikings did win their finale, 14-13 over the Detroit Lions, in what was the last game to be played at the Metrodome. Other head coaches who were fired prior to today: Houston's Gary Kubiak and Cleveland's Rob Chudzinski.

Coaches who are safe include this guy.

It's hard to believe, but as of this writing, Dallas Cowboys head coach Jason Garrett will be the coach in 2014. Cowboys owner Jerry Jones still has faith in the former QB despite a third straight 8-8 campaign which saw Tony Romo fall out of contention after season-ending back surgery. And yeah, let's not forget another heartbreaking loss to get into the playoffs last night as the Cowboys were beat by the Philadelphia Eagles 24-22. Also safe is New York Jets head coach Rex Ryan. The Jets also finished with an 8-8 record and they won their final game against Miami Sunday. 20-7.

No other names have been mentioned this morning, but who knows?
