Eleven might be the magic number of wins when it comes to the Detroit Lions and the playoffs.
The Lions fell out of first place in the NFC North for the first time since September with Sunday's 34-9 loss to the New England Patriots, and if the postseason started today, they'd be on the outside looking in.
One of three NFC teams with a 7-4 record, the Lions would lose a three-team tiebreaker for the final wild-card spot to the Seattle Seahawks, based on their records against common opponents.
Seattle is 4-0 in games against the Arizona Cardinals, Carolina Panthers, New York Giants and Green Bay Packers, while the Lions are 2-2, with losses at Arizona and Carolina.
The Lions have one of the easiest schedules remaining of any team in the NFL, but they might need to win four of their final five games to leapfrog the Seahawks in the standings.
Their next four games are against teams with losing records -- the first three of them at home -- but with a game in Green Bay to end the year, the Lions don't have any room for error the next month.
