The 2013 Oakland Raiders season was the franchise's 44th season in the National Football League (NFL), the 54th overall and the second under head coach Dennis Allen. With a 4–12 record, the Raiders secured their eleventh consecutive non-winning season, and missed the playoffs for an eleventh consecutive season. The Raiders entered the season with a new quarterback in Terrelle Pryor. Pryor started off the season in impressive fashion, with the team almost pulling off the upset in Week 1 against the Indianapolis Colts, and defeating the Jacksonville Jaguars in Week 2. The team and Pryor eventually cooled down, resulting in Pryor being benched for Matt McGloin in the game against the Houston Texans. Before this game, history was made in the game against the Philadelphia Eagles when Eagles quarterback Nick Foles threw 7 touchdown passes, the most passing touchdowns the Raiders had ever allowed in its history. Prior to the season starting, the Raiders brought back defensive back Charles Woodson, who spent the last 7 years with the Green Bay Packers.
The 2013 season was the St. Louis Rams' 76th in the National Football League (NFL), their 19th in St. Louis and their second under head coach Jeff Fisher. The Rams equaled their win total from 2012, but missed the playoffs for a ninth consecutive season.
The 2013 season was the San Francisco 49ers' 64th in the National Football League (NFL), 68th overall and third under the head coach/general manager tandem of Jim Harbaugh and Trent Baalke. This marked the first season since 2004 that quarterback Alex Smith was not on the roster as he joined the Kansas City Chiefs. This was the 49ers' final season playing their home games at Candlestick Park before moving into Levi's Stadium for the 2014 season.
The 2015 season was the Seattle Seahawks' 40th in the National Football League (NFL) and their sixth under head coach Pete Carroll.
The 2016 season was the San Francisco 49ers' 67th in the National Football League (NFL), their 71st overall, their third playing their home games at Levi's Stadium and the only season under head coach Chip Kelly. The season saw the 49ers attempting to rebound from their 5–11 record the previous year, but finished 2–14, with their only wins coming against their division rival Los Angeles Rams. The 49ers also nearly became the first team since the 2001 Carolina Panthers to win their opener and lose the remainder of their games, prior to the 49ers' Week 16 win over the Rams. The 49ers' record was their worst since 2004, when they also finished 2–14. The 49ers' 1–7 home record tied the worst home record in franchise history. As a result, the 49ers fired Kelly and general manager Trent Baalke.
The 2016 season was the Seattle Seahawks' 41st in the National Football League (NFL) and their seventh under head coach Pete Carroll. On October 23, the team played the Arizona Cardinals in a game that ended in a 6–6 tie, the Seahawks' first tie in franchise history. With their win against the Los Angeles Rams in Week 15, the Seahawks claimed their third NFC West title in the last four years. The Seahawks defeated the Detroit Lions in the Wild Card Round, but lost 20-36 to the eventual NFC champion Atlanta Falcons in the Divisional Round.
The 2017 season was the Seattle Seahawks' 42nd in the National Football League (NFL) and their eighth under head coach Pete Carroll. The Seahawks tried to improve their 10–5–1 record from 2016. However, it did not happen because of injuries to key defensive players and poor offensive performances. After the Atlanta Falcons' Week 17 win over the Carolina Panthers, they were eliminated from playoff contention for the first time since 2011. They also failed to achieve a 10-win season for the first time since that same season. This was Russell Wilson's first season not making the playoffs.
The 2018 season was the Arizona Cardinals' 99th in the National Football League (NFL), their 31st in Arizona, and their only season under head coach Steve Wilks. During the off-season, State Farm purchased the naming rights to the Cardinals' home stadium and it was renamed from University of Phoenix Stadium to State Farm Stadium. Although former head coach Bruce Arians retired before the season began, he came out of retirement on January 8, 2019 to become the new coach of the Tampa Bay Buccaneers.
The 2018 season was the San Francisco 49ers' 69th in the National Football League (NFL), their 73rd overall, their fifth playing their home games at Levi's Stadium and their second under the head coach/general manager tandem of Kyle Shanahan and John Lynch.
The 2018 season was the Seattle Seahawks' 43rd in the National Football League (NFL) and their ninth under head coach Pete Carroll. The Seahawks improved on their 9–7 record from the 2017 season, finishing 10–6, the sixth time in seven years that they recorded at least ten wins in a season. They also played in London for the first time in franchise history, defeating the Oakland Raiders 27–3 in Week 6. With a win over the Kansas City Chiefs and eventual league MVP Patrick Mahomes in Week 16, the Seahawks returned to the playoffs; their seventh appearance in the nine seasons under Carroll. However, the Seahawks suffered their first one-and-done postseason campaign since 2004, as they fell to the Dallas Cowboys in the Wild Card round 24–22.
The 2019 season was the Seattle Seahawks' 44th in the National Football League (NFL) and their 10th under head coach Pete Carroll. It marked their first full season since 1996 without longtime owner Paul Allen, who had died during the 2018 season.
The 2020 season was the Arizona Cardinals' 101st in the National Football League (NFL), their 33rd in Arizona and their second under head coach Kliff Kingsbury. It was also the first full season since 1971 without the ownership of Bill Bidwill, who died during the 2019 season.
The 2020 season was the Seattle Seahawks' 45th in the National Football League (NFL) and their 11th season under head coach Pete Carroll. With a win over the Washington Football Team in Week 15, the Seahawks made the playoffs for the third consecutive year. With a Week 17 win over the San Francisco 49ers, they improved upon their 11–5 record from the previous season. For the first time in franchise history, the Seahawks started 5–0. After a Week 16 win over the Los Angeles Rams, the Seahawks clinched the NFC West title for the first time since 2016.
The 2021 season was the Chicago Bears' 102nd season in the National Football League (NFL), their 103rd overall, and their fourth and final under head coach Matt Nagy. This was the first season under the NFL's new 17-game schedule.
The 2021 season was the Arizona Cardinals' 102nd season in the National Football League (NFL), their 34th in Arizona and their third under head coach Kliff Kingsbury. They improved from their 8–8 season from the previous year with a 23–13 victory over the Seattle Seahawks in Week 11. The Cardinals started 7–0 for the first time in 47 years when they were based in St. Louis. With their week 11 win over their division rivals, the Seattle Seahawks, the Cardinals improved on their record from the previous year and clinched their first winning season since 2015. Despite a loss to the Indianapolis Colts in Week 16, the Cardinals clinched a playoff berth for the first time since 2015 after the Minnesota Vikings lost to the Los Angeles Rams.
The 2022 season was the San Francisco 49ers' 73rd in the National Football League (NFL), their 77th overall, and their sixth under the head coach/general manager tandem of Kyle Shanahan and John Lynch.
The 2022 season was the Seattle Seahawks' 47th in the National Football League (NFL) and their 13th under the head coach/general manager tandem of Pete Carroll and John Schneider.
The 2023 season was the Seattle Seahawks' 48th in the National Football League (NFL) and their 14th and final season under the head coach/general manager tandem of Pete Carroll and John Schneider. The Seahawks matched their 9–8 record from the previous year, but unlike 2022, it was not enough to qualify for the playoffs, as they finished in third place in the division behind the San Francisco 49ers and Los Angeles Rams, and in a three-way tie with the Green Bay Packers and New Orleans Saints for the last Wild Card spot, which the Packers claimed via tiebreaker. Despite a 5–2 start, key injuries to Geno Smith, Kenneth Walker III, DK Metcalf, and Devon Witherspoon, and poor defensive play led to the Seahawks losing five of their next six. While the Seahawks would win two games in a row, a loss to the Steelers cost them control of their own destiny. In total, Seattle played 11 games and went 3–8 against teams that finished with a winning record, culminating in a collapse that cost them an appearance in the postseason. This was the second time in three seasons that Seattle missed the playoffs, and was the first season since 2009 that Dave Canales was not on the team's payroll, as the Tampa Bay Buccaneers hired him to be their offensive coordinator for one year.
The 2024 season is the San Francisco 49ers' 75th in the National Football League (NFL), their 79th overall, their eleventh playing their home games at Levi's Stadium and their eighth under the head coach/general manager tandem of Kyle Shanahan and John Lynch. They enter the season as defending NFC Champions. The 49ers failed to improve on their 12–5 record from 2023 with a Week 11 loss to the Seattle Seahawks, and failed to match it after a Week 12 loss to the Green Bay Packers.
The 2024 season is the Seattle Seahawks' 49th in the National Football League (NFL), their 15th under general manager John Schneider and their first under head coach Mike Macdonald. They attempt to improve on their 9–8 record from the previous two seasons, make the playoffs after a one-year absence, and end their three-year NFC West title drought. This is their first season since 2009 that Pete Carroll will not be head coach of the team, as he was reassigned to an advisor role in the offseason.
