With four weeks left in the 2013 NFL regular season, there is more and more conversation about the playoffs and which teams will not only make the playoffs, but which teams might have home field advantage throughout the duration of the post-season.

You don’t have to be a rocket scientist to understand that having the home field is a benefit during the season and also in the playoffs. For the record, from the 2010 season through Week #13 of this year, home teams have won .572 of the games with road teams at .428, a difference of .144. (In the last three NFL playoffs, home teams have an 18-12 record, a .600 winning percentage.)

For some teams, however, the difference between their regular season home and road winning percentage is much greater than the league average of .144 since 2010. The Arizona Cardinals since 2010 are 19-11 (.633) at home and 6-24 (.200) on the road. That .433 difference is the largest of all NFL teams in that time period.

After looking at the records below, you will notice that:

* Only nine of the 32 NFL teams have a .500 or better record at home and on the road… Atlanta, Chicago,  Denver, Green Bay, New England, New Orleans, New York Giants, Pittsburgh, San Francisco.

* Two teams, Philadelphia and Washington, have actually played better on the road than at home since 2010. Only two teams, New England (.700) and Philadelphia (.600) have won 60 percent or more of their regular season road games since 2010.

Here’s a look at each NFL teams winning percentage at home and on the road since 2010.
