The Denver Broncos are entering the 2025 season with renewed optimism, but it’s not quarterback Bo Nix stealing the spotlight. Instead, the defense is shaping up to be the team’s most exciting and dependable asset, earning widespread praise for its talent and depth.

Denver’s defensive unit has been bolstered by key offseason additions, including All-Pro safety Talanoa Hufanga and linebacker Dre Greenlaw from the 49ers. These acquisitions, combined with a stellar supporting cast, have catapulted the Broncos to elite status in defensive rankings. Sharp Football Analysis ranked their secondary first and their front seven second in the league, highlighting the unit’s potential dominance.

The defensive line, featuring Zach Allen , D.J. Jones, and John Franklin-Myers, returns intact after leading the NFL with 63 sacks in 2024. On the edges, pass rushers Jonathon Cooper and Nik Bonitto continue to improve, both coming off double-digit sack seasons. This consistency and chemistry give Denver an edge that few teams can match heading into training camp.

The addition of Hufanga in the secondary is expected to elevate the backfield significantly. Paired with Patrick Surtain II, Riley Moss, and Brandon Jones, the group is positioned to neutralize even the league’s top passing attacks. First-round pick Jahdae Barron also adds depth, ensuring the secondary remains versatile and formidable.

NFL Analysis Points Out Denver Broncos’ Defense, Not Bo Bix, as Reason for Optimism in 2025

Denver’s defense, not Nix, will most likely be the highlight of their upcoming season. This is detailed more in an analysis by Tyler Sullivan for CBS Sports.

Boast arguably NFL’s top defense

While the attention will likely be paid to how Bo Nix develops in Year 2, the most exciting aspect of the Broncos in 2025 is their defense. Denver finished tied for the second-fewest yards per play (5.0) allowed last season, and surrendered the third-fewest points per game (19.0). They spent this offseason further bolstering that side of the ball, adding Dre Greenlaw and Talanoa Hufanga in free agency and using their first-round pick on nickel corner Jahdae Barron.

Injuries remain a concern, particularly for Greenlaw and linebacker Alex Singleton, who is returning from an ACL tear. However, if the unit stays healthy, the Broncos defense could carry the team to playoff contention, regardless of offensive uncertainties.

As the season begins, Denver’s defense stands out as the franchise’s cornerstone. With an exceptional mix of veteran leadership and emerging talent, this group could redefine the Broncos’ identity and fuel their resurgence in the AFC.
