Head coaches in the NFL are held to a special kind of scrutiny.
If his quarterback throws a touchdown pass, he is a genius. If his quarterback throws an interception, he is a moron. If he has a blank expression on his face when his team is winning, he looks intense. If he has the same expression when his team is losing, he looks stupid. If his playbook is not exactly 50-50 between running and passing, he will be accused of not mixing up the play call if his team loses.
In this slideshow, I take a look at who I think are the best head coaches in the league. In my ranking, I take into account regular season records, postseason achievements, and general accomplishments with the team. All of the coaches on this list have been employed as a head coach for at least two seasons and have reached at least one conference championship game. The coaches are not directly ranked by winning percentage or Super Bowl victories, but by overall success in their field.
So sit back and enjoy the ride. It should be a good one.
