Not that long ago, the Lions were 1-6, the Jaguars and Steelers 2-6 and the Packers 4-8. Today, each team heads into Week 18 with a chance to make the playoffs.
In the 89 seasons the NFL has had playoff games (1933-2021), there's never been multiple teams that were at least four games under .500 and rallied to make the playoffs in the same season.
The Packers (8-8) need only to beat the Lions (8-8) at home on Sunday to clinch the NFC's No. 7 seed, and the Jaguars (8-8) need only to win or tie the Titans (7-9) at home on Saturday to win the AFC South.
