The NFL season is officially underway, and Pro Football Focus has released its highest-graded defenses from Week 1.

The Chiefs earned the highest defensive grade of Week 1 at 78.8, helping Kansas City open the season with a 31-10 victory over the Denver Broncos on Monday night.

Kansas City also limited Denver to 176 total yards, the fewest allowed by any NFL defense through Week 1.

The performance came at an important time for a Chiefs defense looking to establish itself early in the 2026 season. Kansas City kept Denver’s offense from generating consistent production and allowed just one touchdown.

The Pittsburgh Steelers and New York Jets both received a 72.8 defensive grade from PFF.

Pittsburgh held Atlanta to just 238 total yards and forced the Falcons to convert only two of 12 third-down opportunities. T.J. Watt and Alex Highsmith each recorded two sacks as the Steelers defense consistently pressured Atlanta’s offense.

The Jets were particularly impressive statistically, allowing only 195 total yards, second-fewest in the NFL behind Kansas City. New York also held Tennessee to 10 points in a 23-10 victory.

Las Vegas generated five sacks and 27 quarterback pressures, with new addition Kwity Paye producing two sacks and eight pressures in his Raiders debut.

The Baltimore Ravens rounded out the top five at 71.9 after limiting Indianapolis to 23 points in a 41-23 victory.
