As promised, the chart shows the NFC's official seeding through the first 11 weeks of the season. If the season ended today, two NFC North teams would make the playoffs, but a third would be eliminated by a tiebreak.
Four division champions and two wild-card teams from each conference advance to the postseason. The Green Bay Packers and Chicago Bears each have 7-3 records, but for the purposes of seeding, the Packers are the NFC North leaders because of their Week 2 victory against the Bears.
The Bears could neutralize that advantage by beating the Packers next month at Soldier Field. The next tiebreak is division record; here is a link to the NFL's full tiebreak procedures.
As you can see, the Minnesota Vikings are one of three teams with a 6-4 record. But at the moment, they would fall short in the tiebreak with the Seattle Seahawks and Tampa Bay Buccaneers because they have lost to both teams this season. The Seahawks would edge the Bucs for the No. 6 seed because they have a better conference record.
