After getting in their own way in the first half, the Bills steamrolled the Steelers in the second half en route to a 26-7 win.
Trailing 7-3 at halftime, the Bills opened the second half with two quick touchdowns set up by turnovers. The first was Christian Benford's fumble return for a score after Joey Bosa strip-sacked Aaron Rodgers on Pittsburgh's first play of the third quarter.
The Bills' second score off a turnover occurred moments later when Josh Allen hit wideout Keon Coleman for a touchdown that was set up by Benford's interception of Mason Rudolph, who briefly replaced Rodgers.
Buffalo made history in the second half. Allen scored his 76th career touchdown run, breaking Cam Newton's NFL record by a quarterback. The Bills -- despite missing several offensive starters that included two on the offensive line -- ran for 249 yards, the most yards ever allowed by a Steelers' defense at Acrisure Stadium. James Cook overcame an early fumble by rumbling for 144 yards on 32 carries.
While Buffalo (8-4) is back in the winner's circle, Pittsburgh (6-6) has lost two straight games and five of its last seven. Sunday was another brutal showing for a Steelers offense that gained just 166 yards and possessed the ball for less than 19 minutes.
Here's a closer look at how the Bills got it done.
Turning point
The game was completely turned on its head on the first play of the second half. Benson's score off of Bosa's strip-sack was the first of Buffalo's 23 unanswered points in the second half.
Pittsburgh's next drive also ended with Benford's hands on the ball after he snared in Rudolph's pass. His pick -- in addition to a 31-yard run by Cook -- set up Allen's backbreaking touchdown pass to Coleman that extended Buffalo's lead to 16-7.
Play of the game
Allen's touchdown pass to Coleman was a thing of beauty. On fourth-and-goal, Allen pump faked before hitting a wide open Coleman, who managed to get by Kyle Dugger and Asante Samuel, who was recently signed by the Steelers.
After going 6 of 12 with an interception in the first half, Allen was 7 of 11 through the air in the second half with two total touchdowns.
Third-quarter dominance
You'd be hard-pressed to find a more dominant quarter than Buffalo's bludgeoning of Pittsburgh in the third quarter. During those 15 minutes, Buffalo outscored the Steelers 13-0 while forcing two turnovers and scoring touchdowns on both sides of the ball. At that point, Cook had already rushed for 135 yards and the Bills had already amassed 218 rushing yards as a team.
Allen, Bills make history
Allen now has more rushing touchdowns than anyone in NFL history after scoring from 8 yards out on third-and-goal. He has 13 more rushing touchdowns than Eagles quarterback Jalen Hurts, who has the third-most rushing touchdowns in league history among quarterbacks.
As a team, Buffalo set the record for the most rushing yards in Pittsburgh by an opposing team since the Steelers started playing at Acrisure Stadium, which opened in 2001. In addition to Cook, the Bills' rushing attack also received a boost from Ray Davis, who picked up 62 yards on nine carries.
Cook, who entered the game as the NFL's season-leading rusher, also led the Bills in receiving yards during Sunday's win.
Slow start,
As alluded to earlier, the Bills largely beat themselves in the first half. They committed several costly penalties on both sides of the ball and committed two turnovers. Pittsburgh parlayed Buffalo's second turnover into their only score of the game, a shortly touchdown run by Jaylen Warren.
After falling behind 7-0, Buffalo offered a foreshadowing of what was going to come in the second half by ending the first half with a 16-play drive that led to their first points of the night, a short field goal by Matt Prater.
Major concern in Pittsburgh
It's safe to say that Steelers fans have reached their breaking point. Fans actually booed during the playing of "Renegade," which is usually a rallying cry for both the the fans and the team. There were also "Fire Tomlin!" chants during the second half, another sign of the fan base's frustration.
It's not an overreaction to state that this is one of the ugliest regular season losses of the Mike Tomlin era. The Steelers gained just 10 first downs, had 166 total yards and were completely run over in the second half. Sunday marked the seventh time this year that the Steelers' offense failed to generate over 300 total yards.
If there's a silver lining, it's that the Steelers will be in first place in the AFC North if they can defeat the Ravens next week in Baltimore.
