Rob Leonard enters his first season as Raiders defensive coordinator facing a roster reset and installation rush

Rob Leonard has been named the Las Vegas Raiders’ defensive coordinator, a promotion that reshapes how the organization will build its defense in 2026. Leonard moves into a top leadership role after three seasons in Las Vegas, most notably working as the defensive line coach and, in 2025, as the run game coordinator. Yahoo Sports, in previewing Leonard’s first year, pointed to a major operational challenge: the Raiders’ defensive personnel could feature as many as seven new starters compared to the prior season. That kind of turnover turns even a “standard” coordinator task into a time-sensitive project, because communication and assignment discipline have to show up before the season starts, not after.

Leonard’s background suggests why the Raiders feel comfortable handing him the play-calling and overall structure. In a team announcement from February, Las Vegas highlighted that during Leonard’s first season as run game coordinator in 2025, the Raiders ranked tied for second in the league in fewest rushing yards allowed per attempt (3.9), while also ranking third in tackles for loss (105). The club also emphasized the pass-rush production tied to that work, including Maxx Crosby reaching Pro Bowl form with 10.0 sacks and 28 tackles for loss. The point of those numbers for Leonard’s coordinator transition is not that they guarantee repeat results, but that he has already built credibility by improving a defense’s fundamentals on one side of the ball.

What Leonard has to prove now is whether those fundamentals can be scaled to the full defense, with multiple position groups learning at once under a single system. Raiders communications described Leonard as the “all-seeing eye” of the defense during his transition, including how he is already adjusting from position coach to overarching coordinator. In a June interview with reporters, Leonard said he wants the unit to play fast, even if it means occasional mental mistakes, because the priority is decision-making rather than hesitation. That tempo philosophy matters in coordinator work, because it affects how the defense fits protection concepts, plays movement-based routes, and keeps coverages synchronized when personnel changes.

A coordinator’s first offseason is also about people, not just schemes. Raiders reporting noted that Leonard was one of three coaches retained by head coach Klint Kubiak from the previous staff group, alongside Luke Steckel and Joe Woods. That matters because retention reduces the amount of cultural reset a coordinator has to manage. At the same time, even with continuity, a group that could have as many as seven new starters has to compress the learning curve for every rep, from pass-rush responsibilities to linebacker leverage to secondary reactions to run-pass options.

The urgency is bigger when you consider the defensive baseline the Raiders are trying to lift. ’s coverage of Leonard’s promotion framed the challenge plainly: Las Vegas finished 2025 ranked 25th in points per game (25.4) and 24th in sacks. That snapshot sets the target for what Leonard must change during the installation period, particularly because pass rush is not an isolated part of a defense. Pressure influences coverage time, which influences third-down results and red-zone competitiveness.

With roster turnover, the “projects” in a first-year coordinator season tend to come in clusters. For Leonard, that cluster likely starts in the front, where he has spent his coaching life, and then spreads outward as new starters and new communication habits meet live-game disguises. Raiders coverage of Leonard’s coordinator adjustment included the way he is tracking multiple groups day-to-day, from going to the defensive backs to checking in with the defensive line during special teams. The practical takeaway is that installation has to be cross-unit, not just a line-by-line teaching session.

What to watch next is not simply whether the defense looks good in isolated drills, but whether it shows cohesion under pressure: crisp rotations, consistent gap integrity, and the ability to keep the defense’s tempo idea intact without blowing coverage structure. Leonard is trying to translate his run-game coordinator leadership and defensive-line expertise into a whole-unit identity, and with a changing starting group, the Raiders will need that identity early. If the defense can improve its fundamentals quickly, it gives the Raiders a stable platform for a season that will be defined by how quickly a young, shifting unit can trust its assignments.
