All the games of the regular season are over, and the playoff spots are officially decided.

The six seeded spots in the American League belong to the Denver Broncos, New England Patriots, Cincinnati Tigers, Indianapolis Colts, Kansas Chiefs and San Diego Chargers.

Among them, the San Diego Lightning faced their rivals Kansas Chiefs in the final week of the game, and finally they went through the test of overtime, defeating their opponents with a score of "27-24" and a free kick advantage, and narrowly won a playoff spot.

The San Diego Lightning finished the season with a nine-seven record, while the eight-eight teams in the American League had as many as four, including the Pittsburgh Steelers, Baltimore Ravens, New York Jets and Miami Dolphins.

But other than that, the other five teams have a very clear advantage within the division, and the team with the worst record is also the team with 11 wins in the season. It can be seen that the gap in strength of the American League is still relatively obvious, so the teams that finally made it to the playoffs are all old faces, lacking novelty and bright spots.

Comparing the playoff lineups of the past three years, it is clear at a glance.

For the 2011 season, the New England Patriots, Baltimore Ravens, Houston Texans, Denver Broncos, Pittsburgh Steelers, and Cincinnati Tigers.

In the 2012 season, the Denver Broncos, New England Patriots, Baltimore Crows, Houston Texans, Indianapolis Colts and Cincinnati Tigers. The only difference is that the Indianapolis Colts take the place of the Pittsburgh Steelers, while the Pittsburgh Steelers and San Diego Chargers are seventh and eighth in the American League, respectively.

For the 2013 season, the roster is as above, with the only difference being that the Kansas Chiefs and San Diego Lightning made the playoffs, while the Baltimore Ravens and Houston Texans fell behind; It's worth mentioning that the Pittsburgh Steelers and Baltimore Ravens are seventh and eighth in the American League, respectively, and only the Houston Texans have been completely confused throughout the season.

Strictly speaking, only the Kansas Chiefs are a new face to make the "upset", having only qualified for the playoffs once in the 2010 season since 2003 - after finishing bottom of the division for two consecutive years, and last season they won the title of vice-president, and this year is the second playoff appearance of the Kansas Chiefs in a decade.

Similarly, only the Houston Texans, an upstart, suffered a total collapse, finishing the playoffs for two consecutive seasons and recording just two wins and 14 losses this season — exactly the same record as the Kansas Chiefs last season, having unfortunately won the vice-squad leader title, and then entering a difficult period of strategic adjustment.

In other words, only the Kansas Chiefs and Houston Texans have slightly disrupted the league over the past three years, and the main competition for the other teams has been concentrated in a relatively fixed seven-team team, which has also made the regular season matchups and playoff battles in the league always lackluster, which is really disappointing.

How to find new ideas in the routine?

Can the Cincinnati Tigers win a playoff game? Can the San Diego Lightning break the shackles and take it to the next level? Are the Kansas Chiefs, who have started the season with nine straight wins, lack stamina, and will this affect the playoff journey? What will happen to the love-hate feud between the Denver Broncos, the New England Patriots and the Indianapolis Colts in the playoffs? Also, Can Peyton Manning vs Tom Brady's fifteenth meeting take place?

And last but not least, five of the six playoff teams have an 11-win regular season record, does that mean there are more playoff matchups? Starting with the Wild Card Match, is the excitement of each matchup worth looking forward to?

When the playoffs begin next week, the answers to these puzzles will be revealed.

This is followed by the League of Nations.

Top seed, National League West champion, Seattle Seahawks, 13-3.

The second seed, the champion of the South Division of the National League, Carolina Panthers, is 12-4.

The third seed, the champion of the National League East, the Philadelphia Eagles, is 10-6.

The No. 4 seed, the champion of the North Division of the Nations League, the Green Bay Packers, won 8, 7 and drew 1.

Next up are the wild card seats.

The No. 5 seed, runner-up in the National League West, San Francisco 49ers, 12-4.

Sixth seed, runner-up in the National League South Division, New Orleans Saints, 11-5.

As mentioned before, the overall pattern of the National League is very chaotic and very close, and the victory or defeat of one game can change the situation of the entire federation.

In the end, the Seattle Seahawks defeated the St. Louis Rams to firmly secure the top seed in the National League, and the San Francisco 49ers defeated the Arizona Cardinals to successfully enter the playoffs; While the Carolina Panthers and New Orleans Saints both defeated their respective regional rivals to make the playoffs, the Carolina Panthers defeated the New Orleans Saints in the sixteenth week of the regular season.

Also, the Philadelphia Hawks defeated the Dallas Cowboys with a score of "24-22" and the Green Bay Packers defeated the Chicago Bears with a score of "33-28", and both winners stepped on the corpses of their rivals in the same district to make the playoffs, joining the ranks of the San Francisco 49ers, firmly taking their fate into their own hands.

From the record data, it can be seen that the competition situation in the National League is complicated, with 12 wins for the San Francisco 49ers and 11 wins for the New Orleans Saints, which can be among the top four seeds in the American League, but they have fallen into the wild card position in the National League; The Philadelphia Eagles' 10-win and Green Bay Packers' 8-win win were far from impressive, but they managed to grab a playoff spot thanks to a general slump in their rivals in the same district.

It is worth mentioning that the Arizona Cardinals, who finished seventh in the National League, have a record of 10 wins and 6 losses, the same as the Philadelphia Eagles, but because the performance of their opponents in the same region is too good, they can only fall into the wild card position of the competition, but they lost to the San Francisco 49ers and the New Orleans Saints and missed the opportunity.

Similarly, the Chicago Bears, who are ranked eighth in the National League, have a record of 8 wins and 8 losses, just half a win behind the Green Bay Packers - the defeat in the final battle of life and death truly explains the mystery of "falling to the finish line", compared to Palmer's depression, missing the playoff spots at the last minute for two consecutive seasons, the Chicago Bears also want to cry.

Within the division, the strong are strong together, and the weak are weak together, which also makes the entire regular season process full of unpredictable variables; What's even more interesting is that the Philadelphia Eagles and Green Bay Packers, who look like underdogs, also have the ability to upset either team, let alone the two teams in the wild card spots, even the top two seeds must be careful, otherwise it will be a matter of minutes to capsize in the gutter.

Of course, in such fierce competition, the gap in strength still exists objectively, Aaron Rodgers' Green Bay Packers and Drew Bliss's New Orleans Saints are undoubtedly the most consistent teams in the National League, and their presence is the biggest guarantee of the team's victory - even if the performance of the defensive group has repeatedly lagged behind, this also makes the four elite quarterbacks join hands again to enter the playoffs after a year, and this ability is the envy of other teams.

A look at the playoff teams in the Nations League over the past three years also reveals some clues.

In 2011, the Green Bay Packers, San Francisco 49ers, New Orleans Saints, New York Giants, Atlanta Falcons, and Detroit Lions.

In the 2012 season, the San Francisco 49ers, Atlanta Falcons, Green Bay Packers, Washington Redskins, Seattle Seahawks and Minnesota Vikings. Among them, all three seats have been replaced, and the proportion of top and bottom has reached 50% - for reference, the New Orleans Saints fell into the dilemma of not having a head coach because of the "spygate", and finally ranked 12th in the National League; The seventh and eighth teams in the National League are the Chicago Bears and the New York Giants, respectively.

In the 2013 season, the roster is as above, and once again, the three seats have been swapped, the Atlanta Falcons, the Washington Redskins and the Minnesota Vikings have all been dropped, and the replacement ratio has once again reached 50 percent, in addition to the familiar faces of the New Orleans Saints, the rise of the Philadelphia Eagles and Carolina Panthers is a surprise.

In addition, the Arizona Cardinals are seventh in the National League this season, and the Chicago Bears are eighth in the eighth place.

The overall pattern is clear at a glance, only the San Francisco 49ers and the Green Bay Packers have made the playoffs for three consecutive seasons, and the two teams have become the first group in the National League, but the other competitors have more or less deviated from their form, which also makes the competition situation of the whole league particularly complicated.

Although the New Orleans Saints missed the playoffs last year, special circumstances must be taken into account, and the team with Drew Bliss is still the first group in the National League.

In the second group, the Seattle Seahawks, who have shown rapid upward momentum, are undoubtedly the leaders, and the Atlanta Falcons, who have been selected in the previous two seasons, can also be considered one of them - but this season they are only 4-12, showing a cliff-like decline, and the Chicago Bears, who have missed the playoffs three seasons in a row but have shown competitiveness for three consecutive seasons.

And then...... There is no then.

In the Eastern Division of the National League, the New York Giants, the Washington Redskins, the Philadelphia Eagles, and the Dallas Cowboys, the four teams are taking turns to sit in the bank.

In the North Division of the League of Nations, in addition to the Green Bay Packers, the Detroit Lions, Minnesota Vikings and Chicago Bears fight each other.

In the League of Nations South, the New Orleans Saints are slightly ahead, the Atlanta Falcons and Carolina Panthers are rising fast, and only the Tampa Bay Pirates have been slow to recover.

In the Western Division of the National League, the San Francisco 49ers, Seattle Seahawks, and Arizona Cardinals have formed an iron triangle, and the St. Louis Rams, who are temporarily behind, are the divisional killers.

In other words, only the Tampa Bay Pirates are the real underdogs, and the other fifteen teams are all capable of fighting, as can be seen from the drastic changes in the playoff spots in the past three seasons, which also means that when the playoff stage comes, all six teams have the strength to reach the top, all of them depend on the play, and no one can say who will have the last laugh!
