ENGLEWOOD, Colo. — The Broncos have made three more hires to their coaching staff.

Denver has hired Ola Adams as assistant defensive backs coach, Derek Haithcock as assistant to head coach and John Vieira as instructional designer.

Adams has 18 years of collegiate coaching experience, including eight years working with defensive backs. Adams spent the last seven seasons at Villanova, where he had stints as the team's running backs coach (2015-16), cornerbacks coach/special teams coordinator (2017-18) and the defensive coordinator/defensive backs coach (2019-21). Adams also spent time with Columbia (2014), Cortland State (2009, 2011-13), Glenville State (2010) and Concord University (2008). Adams was slated to join Temple as co-defensive coordinator and safeties coach before deciding to join the Broncos.

Haithcock joins the Broncos from the University of California, Berkeley, where he was the director of recruiting operations. Haithcock also has a decade of experience with the Raiders as a coaching assistant and assistant to the head coach.

Vieira previously worked with Green Bay as an instructional designer. NBC Sports' Peter King described the role as "a coach for his coaches, a teacher for his teachers on the Broncos coaching staff. [Head Coach Nathaniel] Hackett is eying an expert in education and technology who will work with each coach to improve engagement with players by learning different and more technologically advanced teaching methods."

Denver previously announced the hire of Offensive Coordinator Justin Outten and a slew of assistants.
