Under the NFL scheduling formula, every team within a division plays 16 games as follows:
Home and away against its three division opponents (6 games).
The four teams from another division within its conference on a rotating three-year cycle (4 games).
The four teams from a division in the other conference on a rotating four-year cycle (4 games).
Two intraconference games based on the prior year's standings (2 games). These games will match a first-place team against the first-place teams in the two same-conference divisions the team is not scheduled to play that season. The second-place, third-place, and fourth-place teams in a conference will be matched in the same way each year.
In the wake of the new collective-bargaining agreement, the NFL could shift to a 17-game regular season as soon as the 2021 season.
According to Packers President/CEO Mark Murphy, the league has determined that extra game would be an interconference game based on place in the standings the previous years.
In the Packers' case, that would mean playing the Kansas City Chiefs in an AFC West vs. NFC North matchup. The conferences would then alternate hosting the extra game, so all conference teams would have the same number of home games that year.
