The first year of the NFL's expanded playoffs has left us with seven postseason spots still in play as Week 17 approaches. That's more than in any year since at least 1990, the most recent time the field expanded, and sets up a wild final week of the regular season.

Here is the full postseason outlook and clinching scenarios that lie ahead, along with analysis from ESPN's Football Power Index (FPI), after Sunday night's Packers victory.

1. Kansas City Chiefs (14-1) -- Z

It doesn't matter how it happens, as long as it does happen, right? The Chiefs clinched the AFC's top seed and home-field advantage throughout the playoffs on Sunday, even though they were on the ropes for much of the game. Ultimately, they won when Falcons Pro Bowl kicker Younghoe Koo missed what would have been a game-tying 39-yard field goal with 9 seconds remaining.

The Chiefs will get the AFC's only first-round bye, and their next road game will come either at the Super Bowl or in the 2021 season.

2. Pittsburgh Steelers (12-3) -- Y

The Steelers snapped out of their extended funk at halftime of Sunday's game against the Colts, roaring back from a three-touchdown deficit to win and clinch the AFC North. They moved up to the second spot temporarily, and they will remain there entering Week 17 if the Bills lose Monday night to the Patriots.

3. Buffalo Bills (11-3) -- Y

The Bills' Week 15 victory in Denver did the trick, making them the AFC East champions for the first time since Jim Kelly was their starting quarterback. They found out Sunday, however, that they won't be able to overtake the Chiefs for the No. 1 overall spot.

In terms of finishing at No. 2, they have a tiebreaker with the Steelers. And overall, the Bills are streaking. They have won seven of their past eight games, losing only when the Cardinals connected on a Hail Mary in Week 10. But Pittsburgh holds the advantage at the moment after beating the Colts on Sunday.

4. Tennessee Titans (10-5)
FPI chances to make playoffs: 91%
FPI chances to win division: 66%

The Titans failed to clinch the AFC South title on Sunday night in losing to the Packers, but they'll have multiple opportunities to do so in Week 17, thanks to the Colts' loss in Pittsburgh. The Titans will clinch if they beat the Texans or via a loss by the Ravens, Colts or Dolphins.
