Read our NFL power rankings after Week 18, as we rank all 32 teams from best to worst at the conclusion of the regular season.
The Baltimore Ravens remain top of the class, while the Tampa Bay Buccaneers and Green Bay Packers moved up after clinching playoff places with wins in their final games.
All eyes are now on the 14 teams still fighting for the NFL Championship, and here are our latest NFL power rankings after Week 18:
The Ravens were able to take things easy this week with the AFC number one seed already locked up and Tyler Huntley replaced MVP candidate Lamar Jackson as starting quarterback in Saturday's 17-10 home loss to the Steelers.
That defeat means that every team in the NFL was beaten at least four times this season, but the Ravens remain at +320 odds to win the NFL Championship.

The 49ers also played their back-ups on Sunday, with Sam Darnold replacing Brock Purdy at quarterback in a 21-20 home loss to the LA Rams.
As with Baltimore, their NFL Championship odds remain unchanged at +225.
The Cowboys climb one place to third after a convincing 38-10 road win over the Washington Commanders won them the second seed in the NFC playoffs and clinched the NFC East title.
Having at least two home games will be a real boost to the Cowboys, who were 8-0 at AT&T Stadium this season and only 4-5 on the road.
The Bills got the job done in their final game with a huge victory over the Dolphins to win the AFC East and jump up to the second spot in the conference.
Quarterback Josh Allen remains one of the highest-ceiling, lowest-floor players in the league, though, with 359 passing yards against the Dolphins as well as two poor interceptions.
The Lions are all set for their first playoff game in seven years after shaking off the disappointment of their Week 17 loss to the Cowboys with a narrow home win over the Vikings.
The Chiefs had already clinched the AFC West, but their second-string players were able to add an 11th win of the season, beating the Chargers 13-12 despite a mediocre performance from QB Blaine Gabbert.
The Dolphins lose ground after their costly defeat to the Bills.
They were already assured of a playoff spot, but now have to leave the Florida sunshine to play the defending Super Bowl champions in what are expected to be freezing conditions in Kansas City.
The Dolphins have been hit by injuries on both sides of the ball at just the wrong time.
The Browns rested as many players as they could in their meaningless defeat to the Bengals, losing 31-14 as recent signing Jeff Driskel became the team's fifth starting quarterback of the season.
They are early 2.5-point road favorites for Saturday's wild-card game against the Texans, but might have preferred to have been playing the freefalling Jaguars.
The Rams enter the NFC playoffs as the most in-form team in the conference as they are riding a four-game winning streak after beating the 49ers.
Puka Nucua broke some long-standing rookie receiver records and, along with former Lions QB Matthew Stafford, Cooper Kupp and Kyren Williams, they can provide Detroit with some stiff opposition this week.
The Eagles' fall to earth continued and they finished the season heading for a road game in the wild-card game at 11-6 after winning 10 of their first 11 games.
The situation seems to be getting worse rather than better and they trailed the Giants 24-0 at half-time in a game they were trying to win.
Quarterback Jalen Hurts injured his right middle finger in the game but the only bright spot is that they play in the final wild-card matchup on Monday so have more time to figure things out.
The Buccaneers make a jump of four places after retaining their NFC South title but a 9-0 win over the league's worst team in the Panthers was not the most convincing performance of the week.
Even so, some people will be questioning whether they should even be underdogs at home to the struggling Eagles this week.
Also making a move up the rankings this week are the Green Bay Packers, who held off some early pressure from the Chicago Bears to win 17-9 as quarterback Jordan Love continues to attract more believers.
The Texans came through with the pressure on to beat the Colts 23-19 on the road in a close game.
As AFC South winners, they get a home game this week but they probably won't be pleased to be hosting the Browns, who won 36-22 at NRG Stadium in Week 16, although Houston quarterback CJ Stroud missed that game.
Completing the 14 playoff teams are the Pittsburgh Steelers, who benefited from the Ravens playing their back-ups to secure their 10th win of the year and then celebrated as the Jaguars' loss to the Titans got them into the playoffs.
They start with a visit to the Bills but you've got to be in it to win it. Star pass-rusher TJ Watt is set to miss that game after injuring his knee, though.
The Jaguars are probably lucky to drop just four places after their embarrassing exit from the playoff picture.
They were in the hunt for a first-round bye just a few weeks ago, but five losses in their last six games saw them miss the post-season entirely.
The Bengals achieved what they could in Week 18, avoiding a 0-6 season in the AFC North and securing a winning record by beating the Browns back-ups.
It meant that all four teams in the division were above .500, but the preseason favorites for the division ended up in last place.
The Saints finished the season strongly - a little too strongly for some people's liking as they scored a touchdown out of a victory formation at the end of their 48-17 win over the Falcons - but it wasn't enough to get them into the playoffs.
The Colts came up short in Week 18 with their loss to the Texans and will hope for better next time round when quarterback Anthony Richardson is healthy again.
The Seahawks just beat the Cardinals in their final game but ended up eighth in the NFC playoff standings.
The Vikings put up some resistance against the Lions in their season finale, but now have to decide whether to stick with Kirk Cousins at quarterback next season or try a new approach.
Interim coach Antonio Pierce kept the Raiders' effort levels up in the final weeks as they won three of their last four games.
Whether that is enough to earn him the job permanently we will have to wait to see.
The Bears are another team with a big decision to make at quarterback but they are increasingly expected to move on from Justin Fields as they have the first overall draft pick this year thanks to last season's trade with the Panthers.
The Broncos are also set for big changes after benching Russell Wilson for the final two games. Head coach Sean Payton improved the team after their terrible start, but there is more work to do.
The Titans will have taken some satisfaction from ensuring that the Jaguars joined them in not making the playoffs thanks to Sunday's first win in four games.
RB Derrick Henry said his farewells after the game and head coach Mike Vrabel's future is up for discussion.
Head coach Arthur Smith was fired by the Falcons on Sunday night after three seasons with the team.
The vacancy should be attractive to candidates as the team has a ton of young offensive talent that just needs a top-level quarterback and some better leadership.
The Cardinals won't be too upset about missing the late field goal that would have beaten the Seahawks on Sunday as it means they get the fourth pick in the draft and they actually have better prospects for next season than their 4-13 record might suggest.
The Jets finished with a more respectable 7-10 record after a 17-3 win over the Patriots in a snowstorm on Sunday.
Their season was lost when Aaron Rodgers went down injured on their fourth offensive play of the year and they will hope for better next time around.
The Giants ended on a high note by upsetting the Eagles to end a run of three straight losses.
They are another team that needs to decide on a long-term quarterback if it's not going to be the injury-prone Daniel Jones.
The Chargers lost eight of their last nine games after starting the season with high hopes but their new head coach will still have some talent to work with.
Bill Belichick just had his worst season in 29 years as an NFL head coach, but he gave no sign at his Monday press conference that any decisions had yet been made about his future with the team.
He will no doubt attract interest from elsewhere if the Pats decide to move on.
The Commanders' eighth straight loss was followed by head coach Ron Rivera being fired on Monday and the second pick in the draft is expected to be used to acquire a new franchise quarterback.
The Panthers have been a disaster all season and GM Scott Fitterer was fired on Monday, following head coach Frank Reich, who lasted only 11 games, out of the door.
