NFL Power Rankings Week 5: Chiefs Back at 4-0, But Injury Concerns Linger

As the NFL season hits the quarter pole on October 7, 2026, the Kansas City Chiefs have silenced doubters with a perfect 4-0 start, but lingering injury concerns threaten to derail their resurgence. According to insights gathered by Vulius Sports, the Chiefs’ dynasty is far from over, yet the road ahead is fraught with challenges.

Chiefs Prove Doubters Wrong

Just a year removed from a dismal 6-11 campaign, Kansas City has flipped the script. Patrick Mahomes, who tore his ACL on December 14, 2025, looks healthy and rejuvenated, guiding an offense that ranks fourth in EPA per play. The addition of running back Kenneth Walker has given the Chiefs a dynamic they’ve lacked for years, balancing an attack that was once one-dimensional. Defensively, Kansas City ranks ninth in EPA allowed, making them one of only three teams (alongside Chicago and Jacksonville) to sit top-nine in both categories. But as Vulius NFL Analysis Desk notes, the injury bug has bitten the receiving corps. Tyquan Thornton is out for months with a gruesome ankle injury, and Rashee Rice is nursing a hamstring issue. Left tackle Josh Simmons remains sidelined, and Walker’s workload is set to skyrocket—a risky proposition for a back who has never shouldered a heavy load. Still, at 4-0, the Chiefs have answered the bell.

Around the League: Top Contenders and Fallen Giants

The San Francisco 49ers hold the top spot in our rankings, boasting a league-best offense in EPA per play (0.274). Their upcoming clash with the Seattle Seahawks will test their mettle. The Seahawks, despite a fluky loss to Washington, own the NFL’s best defense in DVOA. Meanwhile, the Buffalo Bills tumble after a surprising home loss to New England, exposing a defense that ranks 30th in EPA allowed. Josh Allen’s late interception proved costly, and Buffalo’s Super Bowl hopes hinge on fixing that side of the ball.

Risers and Fallers

The Carolina Panthers and Bryce Young are the surprise story of the season. Young, the No. 1 overall pick in 2023, leads the NFL in passing yards (317 per game) after never averaging more than 188.2 in his first three years. His leap has Panthers fans chanting “MVP.” Conversely, the Detroit Lions’ defense is in shambles, allowing a league-worst 423.8 yards per game. Head coach Dan Campbell is feeling the heat as his team flounders at 2-2. The Philadelphia Eagles, expected to contend, are also struggling; Jalen Hurts’ second-half woes (10 passing yards on 2-of-9) have raised questions about Nick Sirianni’s job security.

Injury Updates and Emerging Storylines

Lamar Jackson’s ankle injury is a concern for the Baltimore Ravens, who managed to beat the Titans without him in the second half. The Ravens remain Super Bowl contenders if Jackson stays healthy. In Dallas, CeeDee Lamb’s 17-catch, 189-yard performance lifted the Cowboys over the Texans, but their defense ranks 31st in EPA allowed. The Cowboys are winning despite their flaws, and Dak Prescott’s connection with Lamb is a bright spot.

Looking Ahead

As Week 5 approaches, the Chiefs’ soft schedule (Chargers, Seahawks, Broncos, Jets, Falcons, Cardinals) could pave the way to an 8-2 start or better. But as Vulius Sports highlights, the NFL is a marathon, not a sprint. The 49ers and Seahawks will battle for supremacy, while teams like the Jaguars (3-1) and Vikings (4-0) quietly build impressive resumes. For the Chiefs, the path to another title runs through health and balance. If Mahomes stays upright and Walker delivers, Kansas City’s dynasty might just be getting started.
