After a two-month whirlwind of changes and firings, the dust has settled on the Broncos’ defensive staff for 2025 — with one young coach earning a big promotion.

It’s been six years since Isaac Shewmaker graduated from Alabama. It’s been four years since he joined the NFL ranks, first spending a couple years as a defensive quality-control coach with the Chargers before being hired in the same role by Broncos head coach Sean Payton in 2023.

Now, he’s getting elevated to a general linebackers role, the club announced Thursday. It’s one of the most notable title changes amid a swath of staff updates, with another name sure to catch the eye of Bronco faithful: former Denver linebacker and 2015 Super Bowl champion Todd Davis will step into his first NFL coaching role.

Shewmaker’s fellow former QC analyst Addison Lynch was promoted to cornerbacks coach after working with the group heavily in 2024, a coaching title that didn’t exist on Denver’s staff last year. The club also confirmed the hire of former University of Tennessee assistant Brian Niedermeyer in a defensive quality-control role, and minted Davis alongside him.

Davis told The Post Wednesday that he’d “probably primarily” help with the back end of the defense, including the linebackers and secondary. Senior defensive assistant Joe Vitt will likely have a hand alongside Shewmaker with the Broncos’ linebackers, as well. The four-decade-plus NFL vet once coached linebackers with Payton on the Saints, including a brief stint in 2014 as Davis’ position coach.

Defensive pass game coordinator Jim Leonhard, who was hired by Payton in February 2024 from the University of Illinois, was given an assistant head coach title alongside new special teams coordinator Darren Rizzi. The Broncos also made some tweaks to their strength and conditioning staff, as former assistant Shaun Snee was promoted to director of the club’s strength program, with head strength coach and longtime Payton associate Dan Dalrymple still maintaining his former title. Former Oregon assistant strength coach Taylor Porter has also been hired to Snee’s staff.
