Just the opposite. All the underdogs lost. They just all happened to be the home teams.
That's the way it is today in the NFL, a lot changes over a course of the year, and the teams with the best records aren't necessarily the best teams when the playoffs start, due to injuries. I pretty much thought this past weekend would go the way it did. And I think there's a good chance that 2 or even 3 road teams can win this weekend's game.
