Updated NFL Power Rankings: Where do the final three undefeated teams stand after four weeks?

ESPN's NFL Power Rankings evaluated all 32 teams entering Week 5 of the 2026 season, highlighting early trends across the league. Following the first four weeks, the San Francisco 49ers, Kansas City Chiefs, and Minnesota Vikings stand as the NFL's only remaining undefeated teams. Meanwhile, last season's 14 playoff qualifiers have struggled out of the gate, combining for a 30-26 record—the lowest winning percentage by returning playoff teams in 15 years.

Key movements include the Jacksonville Jaguars climbing into the top five after defeating Cincinnati, while the Philadelphia Eagles dropped out of the top 10 following a fourth-quarter collapse against the Los Angeles Rams. The Cleveland Browns also surged into the top 20 after winning three straight games to share the AFC North lead with the Baltimore Ravens.
