A major defensive coaching overhaul reshapes the BYU Cougars ahead of the 2026 season
In short: Following the departure of key defensive staff to the University of Michigan, Brigham Young University moved quickly to restructure its leadership. Under the guidance of head coach Kalani Sitake, the Cougars executed a series of strategic promotions and new hires to stabilize the program before the upcoming Big 12 campaign.
The 2026 season for the Brigham Young University football program began with significant personnel changes within the defensive coaching unit. In early January, the team saw the exit of defensive coordinator Jay Hill and cornerbacks coach Jernaro Gilford, both of whom accepted positions with the University of Michigan. These departures necessitated a rapid reorganization of the coaching staff to maintain continuity at LaVell Edwards Stadium.
To fill the leadership void, the university promoted Kelly Poppinga to defensive coordinator on January 8, 2026. Simultaneously, Sione Po'uha stepped into the role of associate head coach. The restructuring continued with the addition of Demario Warren, recruited from Boise State, and Lewis Walker, who joined from North Dakota State. These moves allowed the program to refine specific positional responsibilities, including the oversight of the defensive line, inside linebackers, and safeties.
Further adjustments solidified the coaching hierarchy, with Justin Ena taking on the role of special teams coordinator and Chad Kuaha'aha'a being elevated to coach the outside linebackers. These changes, occurring in the weeks following the initial staff departures, represent a calculated effort by Sitake, now in his 11th year, to fortify the team's defensive identity. The success of these new assignments remains a focal point as the Cougars prepare for their competitive schedule within the Big 12 Conference.
The fluidity of the coaching staff highlights the challenges of maintaining stability in modern college football. By promoting from within and strategically recruiting from other institutions, the program aimed to minimize disruption. Whether these tactical shifts in defensive management will translate into on-field performance during the 2026 NCAA Division I FBS season is a question that will be answered as the team begins its campaign.
