After a Week 8 defined by blowouts, the pendulum swung in the other direction in Week 9, with nine of the 11 games in the 1 p.m. ET or 4 p.m. ET window decided by a touchdown or less. The razor-thin margin between losing and winning magnified the significance of this week's worst performances. Here are five that stood out most. Cincinnati Bengals defense The Bengals defense is the gift that keeps on giving to opposing offenses. On Sunday, the unit reached its nadir (things can't possibly get any worse, right? Right?) in a wild 47-42 home loss to the Chicago Bears (5-3). Cincinnati's miraculous comeback, which included a successful onside kick attempt with 1:43 remaining and quarterback Joe Flacco throwing for 470 yards, was undone by a 58-yard touchdown pass from Bears quarterback Caleb Williams to rookie tight end Colston Loveland. At the season's midway point, the Bengals (3-6) have once again dug themselves into a hole that appears too steep to get out of. And just like last season, their horrid defense is why. Detroit Lions offensive line Lions quarterback Jared Goff was constantly harassed in a 27-24 upset home loss to the division-rival Minnesota Vikings (4-4). Detroit's line had arguably its worst game of the season, with Goff being sacked five times. Running backs Jahmyr Gibbs and David Montgomery averaged 3.3 yards per carry, combining for 65 yards on 20 carries. Injuries played a role as Detroit fell to 5-3, but that's also a concerning sign for the future. Starting left guard Christian Mahogany suffered a knee injury, and after the game, head coach Dan Campbell told reporters the 2024 sixth-rounder would be out "for a long time, probably." Starting tackles Taylor Decker (knee) and Penei Sewell (shoulder) also suffered injury scares that must be monitored, as did starting right guard Tate Ratledge (shoulder). Green Bay Packers red-zone offense The Packers (5-2-1) suffered the most unexpected loss of Week 9, falling at home, 16-13, to the Carolina Panthers (5-4). With better red-zone production, Green Bay might have easily walked away with a win. The offense sputtered numerous times inside Carolina's 20-yard line, scoring one touchdown in five opportunities. Green Bay settled for two field goals, had a turnover on downs and a fumble, and another possession that stalled at the Panthers' 25-yard line ended with a missed field goal. The Packers out-gained the Panthers, 369-265, including 265-102 through the air, but thanks to their inability to finish drives, the game was much tighter than it had any business being. It cost Green Bay a victory and control of the NFC's 1-seed. Indianapolis Colts quarterback Daniel Jones Did the clock strike midnight on Jones' incredible 2025 comeback? The former first-round pick looked more like the quarterback who was benched by the New York Giants last season than the one who guided the Colts to seven wins in their first eight games during a 27-20 loss to the Pittsburgh Steelers (5-3). Jones ended 31-of-50 for 342 yards, one touchdown and three interceptions. He also lost two fumbles and was sacked five times, losing 29 yards. ESPN NFL writer Benjamin Solak shared some troubling numbers after the game, revealing that Jones has seen an alarming uptick in pressure-to-sack rate over the past two weeks (33.3 percent, 27.8 percent) after managing pressure well through his first seven games. Sunday may have simply been a blip, but it could also be an ominous sign for the back-half of the season. Kansas City Chiefs quarterback Patrick Mahomes At least one quarterback showed in the hyped 2025 chapter of the Patrick Mahomes-Josh Allen rivalry. The Buffalo Bills quarterback and 2024 league MVP was nearly flawless, going 23-of-26 for 273 yards and three total touchdowns. Mahomes, meanwhile, had his worst NFL game, at least in terms of completion percentage. He was 15-of-34, completing fewer than 50 percent of his pass attempts for the first time in eight seasons as a starting quarterback, for 250 yards and an interception. Mahomes' 57.2 passer rating was the second-lowest of his career. We're used to seeing Mahomes play his best on the biggest stages, making his flop in the high-stakes AFC showdown especially jarring. He's still the best quarterback in football, but Sunday was a reminder that even the greats aren't always great.
