The Playoffs begin in early January following the regular season, so the year represents the season rather than the year the game took place.
The top 7 per conference make the playoffs, for a total of 14 teams.
#1 seed automatically gets a bye week and seeds #2-#7 play in the Wild Card Playoffs (#2 vs #7 / #3 vs #6 / #4 vs #5).
The lowest remaining seed plays the #1 seed in the Divisional Playoffs and the remaining seeds would play against each other.
Prior to the 2020 season, the top 6 teams per conference qualified for the playoffs.
In 1967-1969, the conferences were split into two divisions each. The Division Champions would play each other in the Conference Championship Games with the champions contesting the NFL Championship Game. The winners of the NFL Championship Game would play the AFL Championship Game winners in the Super Bowl.
