The Denver Broncos currently have the best defense in the NFL. They allowed the sixth-lowest average quarterback rating (86.2) and led the league in Dropback EPA, a key metric for pass defense. Their offseason additions, including linebacker Dre Greenlaw, safety Talanoa Hufanga, and first-round defensive back Jahdae Barron, have strengthened an already elite secondary, making Denver's pass defense arguably the best in the league for 2025
. Close behind are the Houston Texans, who ranked fourth in Success Rate allowed last year and boast the NFL's best edge-rusher duo in Will Anderson Jr. and Danielle Hunter. Their defense excels in pass rush and has a strong secondary led by Derek Stingley Jr. and Kamari Lassiter. Houston's defense was dominant in the 2024 playoffs and looks poised to be one of the top units again in 2025
. Other notable defenses include the Dallas Cowboys and Buffalo Bills, both expected to be in the top 10 with key players healthy and offseason improvements made
. In summary, the Denver Broncos lead as the best defense in the NFL for 2025, followed by the Houston Texans as a close contender.
