In 1990, the NFL expanded the playoff field from 10 to 12 teams, resulting in four (not two) teams earning a bye. More often than not, the home team that has had a week off wins. But the road teams still have a chance to get lucky.
For the 29 postseasons since the change was made, the home teams have swept the divisional round eight times. That’s 27.5 percent of the years utilizing the 12-team format. So in 72.5 percent of the years since the current formula was adopted, at least one road team has won in the divisional round.
Specifically, 13 times the home teams have gone 3-1 in the divisional round. Seven times, there has been a split. Once, in 2008, the visiting teams won three of the four games.
In the 10 seasons from 2005 through 2014, the road teams had a remarkably good stretch, winning 16 of 40 games (40 percent). Over the past four postseasons, however, the home teams have gone 13-3 collectively.
All four home teams are favored to win this weekend, as they usually are. In the 30th year of the current format, chances are at least one will lose. One of these years, all four will.
Regardless, the home teams are more likely to feel the pressure. Some could be feeling a little rusty. And one lucky punch early in the contest could turn a potential blowout into a close game, and if the game stays close into the fourth quarter, anything can happen.
