Yes by adding a single wild card team because they had 3 divisions in each conference so they gave the Dolphins coached by Shula a second chance to win a road game to prove they deserve a spot because they needed a 4th team.
Then they added a second wild card team and now a third. At no point did they deserve a home game.
The NFL began with two divisions and just those two division winners facing off for the majority of the NFL seasons with no other game other than division matches when the two division teams were tied for first.
Its the essence of every championship won by Lombardi . If they want to change the system then take Lombardis name off the trophy and put Don Shulas name on the trophy. You know Shula the coach with the most wins, the coach who got left out of the playoffs with best NFL record so Lombardi could win Superbowl II, the coach who had the best non-division winner rercord when they created the wild card spot.
