Last season we entered the divisional round of the playoffs with a No. 5 seed (L.A. Chargers) and two No. 6 seeds (Philadelphia and Indianapolis) making a push for the conference championship game. The year before that, we had one six (Atlanta) and a five (Tennessee).
There are some seasons where a scratch field tears its way through the playoffs, like in 2016 when the No. 3 and No. 4 seeds in each division survived the wild-card round respectively, but most of the time we can expect at least one upset, especially this year when the talent seems to be more evenly distributed throughout the field.
