Following the team's 7–9 finish the previous season, their first losing record since 2000, the Patriots spent a record $163 million in guaranteed money to sign new free agent acquisitions. 11 free agents were added to the roster on March 19, with the largest contracts awarded to linebacker Matthew Judon, tight ends Hunter Henry and Jonnu Smith, cornerback Jalen Mills, and wide receiver Nelson Agholor. In the 2021 NFL draft, New England selected quarterback Mac Jones 15th overall, marking the first time the Patriots drafted a first-round quarterback since Drew Bledsoe in 1993. Jones also became the first rookie quarterback to start for the Patriots since Bledsoe after he was named the starter ahead of the season opener.
The Patriots began the season 2–4, but won eight of their next 11 games and finished with a 10–7 record to secure a wild card berth. In their first playoff appearance without quarterback Tom Brady since 1998 and their first (and only) as a wild card under Belichick, they were defeated 47–17 by the division rival Buffalo Bills, the worst postseason loss of Belichick's tenure. The playoff game was also the Patriots' last with Belichick.
March 18 - Offensive tackleMarcus Cannon, the Patriots' 2021 fifth-round selection (No. 158 overall), and 2021 sixth-round selection (No. 194 overall) were traded to the Houston Texans for the Texans' 2021 fourth-round selection (No. 122 overall, originally acquired from Arizona) and 2021 sixth-round selection (No. 187 overall).[1]
August 26 - The Patriots' 2022 seventh-round selection (originally acquired from Houston) and 2023 fifth-round selection were traded to the Baltimore Ravens for cornerbackShaun Wade.[1]
The Cincinnati Bengals'2021 second-round selection (No. 38 overall) was acquired in a trade that sent the Patriots' 2021 second-round selection (No. 46 overall) and two fourth-round selections (No. 122 and 139 overall) to the Bengals.[49]
The Patriots forfeited their third-round selection as the punishment for illegal filming of the field and sidelines by the team's television crew of a 2019 game between the Cincinnati Bengals and Cleveland Browns.[50]
The Houston Texans' 2021 fourth-round selection (No. 122 overall) and 2021 sixth-round selection (No. 188 overall) were acquired in a trade that sent offensive tackleMarcus Cannon, the Patriots' 2021 fifth-round selection (No. 158 overall), and the previously acquired Dallas Cowboys 2021 sixth-round selection (No. 194 overall) to the Texans.[51]
A sixth-round selection (No. 185 overall) was acquired in a trade that sent wide receiverDemaryius Thomas to the New York Jets.[52] The Jets re-acquired this selection when the Patriots traded two of their 2020 fourth-round selections and this 2021 sixth-round selection in exchange for a 2020 third-round selection.[53]
In rookie quarterback Mac Jones' first NFL start, a back-and-forth affair against divisional opponent Miami was sealed when Patriots running back Damien Harris fumbled the ball in the fourth quarter, allowing the Dolphins to run out the clock.[57] With the close loss, the Patriots began the season 0–1 for the first time since 2017.
A battle of rookie quarterbacks saw Zach Wilson of the Jets throw four interceptions to the Patriots defense, allowing New England to coast to a 25–6 win, its 11th straight win over divisional rival New York. Mac Jones completed over 70% of his passes for the second game in a row.[58]
Jones threw three interceptions, including a pass bobbled by tight end Jonnu Smith before being returned by P. J. Williams for a touchdown, as the Patriots lost to the Saints 28–13 and dropped to 1–2.[59] This was also the Patriots' first loss to the Saints since 2009.
This game marked former Patriots quarterback Tom Brady's first return to Gillette Stadium since leaving the Patriots after the 2019 season, as he was cheered by the Patriots' home crowd during pre-game introductions before being jeered during the game. During the rain-soaked, back-and-forth contest, Brady was held without a touchdown and completed just over half of his passes; he was held to his third lowest passer rating - 70.8 - since joining the Buccaneers but led them to a go-ahead field goal just after the two-minute warning. Jones, who passed for 2 touchdowns and an interception, led the Patriots into position for their own field goal, but Nick Folk's 56-yard attempt hit the left upright, sealing the loss for the Patriots to their former franchise quarterback.[60]
Despite being down 22–9 to Houston at one point, the Patriots came back to win – coincidentally in the same stadium where they overcame a 28–3 deficit to the Atlanta Falcons to win Super Bowl LI. Aside from a missed extra point in the first half, Nick Folk made four field goals during the game, including the game-winner with 15 seconds left in the game.[61] With the win, New England improved to 2–3, taking sole possession of 2nd place in the AFC East.
This was the Patriots' first overtime game since the 2018 AFC Championship game against the Kansas City Chiefs. This was the Pats' first loss to the Cowboys in 25 years and their first home loss to them in 34 years.
With the win, the Patriots improved to 4–4 on the season. It was the Patriots' seventh straight win over the Chargers. Their last loss came on October 12, 2008 in San Diego.
CAR – Christian McCaffrey – 4 receptions, 54 yards
The Patriots intercepted Panthers quarterback Sam Darnold three times en route to victory, including an 88-yard pick-six by J.C. Jackson. New England improved to 5–4 on the year and 4-0 all-time vs. Darnold. This was also the Patriots first win over the Panthers since 2009.
The Patriots outplayed the Browns on both sides of the ball. Mac Jones had one of his better games as a rookie, completing over 80 percent of his passes for three touchdowns and no interceptions as the Patriots converted 7 of 9 third downs. The defense only allowed points on the first drive of the game, held the Browns to 1 of 11 on third down, and knocked Browns quarterback Baker Mayfield out of the game in the third quarter.[62] With Damien Harris sidelined with a concussion from the Panthers game,[63]Rhamondre Stevenson served as the primary running back, rushing for 100 yards and two touchdowns.[62] With the score 38–7 in the fourth quarter, Brian Hoyer replaced Jones and threw the pass that ended Jakobi Meyers' record touchdown drought.[64]
The Patriots defense put up a show against a banged up Titans team. The offense was only forced to punt once but struggled to finish drives and get the run game going, resulting in five Nick Folk field goals. Mac Jones threw for 310 yards, and completed a pair of touchdown passes to Kendrick Bourne, with Damien Harris adding a touchdown late in the fourth quarter on the ground. Cornerback J. C. Jackson secured his seventh interception of the season, while the rest of the defense forced five fumbles, three of which were recovered by the Patriots. The Patriots improved to 8-4 for the AFC East division lead and an overall second place in the AFC.
The Patriots entered the game in first place in the AFC following the Baltimore Ravens' loss the previous day, and were playing for first place in the AFC East. The game was impacted by 40 mph (64 km/h) winds;[66] Belichick noted after the game that the winds in the Patriots' Week 17 game in Buffalo in 2008 were "way worse".[67]
The Patriots drew up a run-heavy game plan in which Jones attempted just three passes, completing two for 19 yards (in 2008, Cassel completed six of eight passes for 78 yards). The Patriots ran the ball 46 times, for over 220 yards, utilizing a sixth offensive lineman on the majority of their offensive snaps.[66] The three pass attempts were the fewest in a game since 1974 (when the Bills attempted just two in a game), the fewest in franchise history, and the fewest by a winning team in 30 years.[68]
The Patriots defense was also stout: the Bills' only touchdown came after a N'Keal Harry muffed punt, and Myles Bryant broke up a fourth-down pass in the red zone late in the fourth quarter to preserve the Patriots' 14–10 win.
The Patriots had their bye week after this game, making it their latest regular-season bye since their Week 16 bye in 2001.[69]
The Patriots were flat for much of the game, being shut out in the first half for the first time in 99 games. A late second half comeback brought the Patriots to within three points, but fell short when Jonathan Taylor put the game away with a 67-yard touchdown run. With the loss, the Patriots fell to the #3 seed in the AFC prior to Week 15's Sunday games, while still maintaining first place in the AFC East. It was also the first time the Patriots lost to the Colts since Week 10 of the 2009 season.[70] The Patriots gave up 226 rush yards in the loss.
This was the first time in five years the Pats and the Bills split the season series. Because of this loss (their second straight after a bye week), the Pats fell to the #6 seed in the AFC playoff picture. The Bills did not have a single punt in this game.

In New England's first playoff game since the departure of quarterback Tom Brady, they were unable to stop the Bills and quarterback Josh Allen defensively, with the Bills being the first team in NFL history to never punt, kick a field goal or turn the ball over on any of their drives (every Buffalo offensive possession ended in a touchdown or was the end of the game).[71] It was the New England Patriots' worst playoff loss in franchise history.
