Bills Take No. 1 as NFL Power Rankings Shift in Week 8

The Buffalo Bills have claimed the top spot in the latest NFL power rankings after a turbulent weekend reshaped the league's standings. Published by The Athletic, the Week 8 assessment places Buffalo first, while the Minnesota Vikings remain the NFL's only undefeated team and the Los Angeles Chargers are the only team without a win.

The rankings reflect a weekend in which three of the previous top-five teams lost, two of the league's three previously unbeaten teams suffered setbacks, and one of the two winless teams secured its first victory. The analysis also identifies a potential weakness or notable strength for each team as Halloween approaches.

Buffalo, now 5-1, climbed from third place despite concerns about its pass defense. According to the analysis, the Bills rank fourth-worst in the league in expected points added per dropback and third-worst in overall defense. They have allowed more than 250 passing yards in five of their six games.

The San Francisco 49ers fell from first to second after losing 29-20 to the Atlanta Falcons. San Francisco, which stands at 6-1, played without its top five wide receivers, while Christian McCaffrey also missed time. Quarterback Brock Purdy threw two interceptions, although the 49ers generated 105 more yards of offense than Atlanta.

The Kansas City Chiefs dropped from second to third following a 20-3 defeat against the Seattle Seahawks. The loss marked the first time in Patrick Mahomes' career that his offense failed to reach the end zone. The assessment suggests Seattle's defensive performance was a major factor in the result.

The Minnesota Vikings held fourth place after beating the Indianapolis Colts 16-10 to improve to 6-0. The team's running game remains a concern, although the Vikings received encouraging news that Aaron Jones was not expected to miss an extended period. According to the analysis, Minnesota scored 125 points during its first six games, matching the 1973 Vikings and trailing only the 1978 Rams, who scored 116, among the cited teams' six-game starts over the past 90 seasons.

The Chicago Bears made one of the biggest upward moves, climbing from eighth to fifth after defeating the New England Patriots 30-24 on Thursday. Chicago improved to 5-2, with quarterback Caleb Williams completing 71 percent of his passes and averaging 8.2 yards per attempt, according to the analysis.

The Denver Broncos remained sixth after beating the Arizona Cardinals 30-16. Denver improved to 5-2, and quarterback Bo Nix reached 19.9 mph during a 62-yard touchdown run, according to Next Gen Stats. The performance offered evidence that his surgically repaired right ankle was holding up during the game.

The Seattle Seahawks rose from 10th to seventh after their defense limited Kansas City to three points. Seattle improved to 4-3 and continued a strong run against opposing passing attacks. ESPN Research reported that the Seahawks became the first team since the 1984 Cleveland Browns to hold each of their first seven opponents below 180 passing yards. Seattle also allowed a league-low 3.99 yards per play, the lowest figure through seven games for any team since the 2019 New England Patriots, who allowed 3.96.

The Jacksonville Jaguars remained eighth at 4-2 after a bye week. Their kicker, Cam Little, converted all four field-goal attempts from at least 54 yards over his previous three games, giving Jacksonville a significant long-range scoring option.

The Detroit Lions stayed ninth after defeating the Green Bay Packers 20-17 in a divisional matchup. Detroit improved to 4-2, but questions remain about its pass defense despite Brian Branch's return to the lineup. The analysis places the Lions fourth-worst in expected points added per play on opposing dropbacks, a weakness that could affect their position among NFC contenders.

Buffalo's next game is against the Baltimore Ravens on Sunday at 1 p.m. Eastern time. Minnesota will visit Detroit at the same time, while Kansas City is scheduled to face Denver on Sunday at 4:25 p.m.

Eastern time. Seattle will host Chicago on Monday at 8:15 p.m. Eastern time.
