Raiders 2026: Defense hinges on Leonard’s aggressive plan

Rob Leonard’s aggressive vision

Coach Rob Leonard will be the catalyst for Las Vegas’s defensive overhaul in 2026. He has spent recent seasons absorbing philosophies from Patrick Graham, Mike MacDonald and Brian Flores, promising a blend of aggression, adaptability and player‑focused accountability. Leonard’s emphasis on quick, high‑tempo fronts and relentless pressure could reshape a unit that has often struggled to keep opponents off‑balance. If he can synthesize those influences into a cohesive game plan, the Raiders could field one of the league’s most daunting sets of defenders.

The coordinator’s track record suggests he values effort and attack, traits that have been lacking on the Raiders’ back‑ends in previous campaigns. His ability to manage multiple schemes simultaneously makes him a true wildcard for the season. Success will depend on executing complex coverages without sacrificing the aggressive mindset Leonard preaches. Should the system click, the defense may become the foundation for playoff aspirations.

Secondary shake‑up and rising young talent

The Raiders’ cornerback and safety corps is undergoing a major transition this offseason. Returning starter Eric Stokes enjoyed a breakout season and is still regarded as a top‑15 corner in the NFL. Safety Jeremy Chinn will add flexibility, while Taron Johnson arrives from Buffalo to provide depth across nickel, free‑safety and slot roles. Veteran Darien Porter, who logged roughly half of the defensive snaps as a rookie, faces competition from newcomers Jermod McCoy and Hezekiah Masses. If McCoy stays healthy, he could become the Raiders’ premier corner, pairing with Stokes to form a sturdy boundary duo. Treydan Stukes, another rookie, is slated for slot and free‑safety duties, offering additional playmaking potential. The secondary’s cohesion will dictate how well the defense can dismantle opposing offenses.

Johnson’s versatility will be critical, but his declining age means consistency in the slot is essential. The Raiders aim to rotate their secondary extensively, with the nickel position a focal point for Leonard’s defensive philosophy. A well‑integrated unit could turn the back‑field into a strength, offsetting earlier deficiencies. Young players will need to absorb complex responsibilities quickly, and their development will be a key metric for the 2026 campaign.

Interior line upgrade with Booker & Hemingway

Thomas Booker and Tonka Hemingway are the newest pillars of Las Vegas’s defensive line, each bringing pass‑rush expertise to a historically weak interior unit. Booker displayed solid run‑stopping improvement late in the season, showcasing the ability to anchor and generate pressure. His generated‑sack numbers placed him among the league’s top performers, despite lacking traditional sack credits. Hemingway, while not expected to play every down, offers explosiveness and a knack for generating pressure in limited snaps, posting four sacks and 15 pressures last year. Their combined potential could push the line toward 35 pressures and five sacks, a marked uplift from recent seasons. With the Raiders’ run defense historically porous, the two new tackles could provide both pass disruption and occasional run‑containment. The success of Booker and Hemingway will hinge on maintaining health and refining technique, but they present the best chance to elevate the defensive front.

Their pass‑rush skills are complemented by athletic movement in stunts and loops, allowing them to penetrate gaps quickly. If they can sustain that output, the Raiders may no longer rank among the NFL’s worst interior lines. The defensive line’s improvement will also affect how the pass rushers behind them operate, giving the defense more balanced options.

Malcolm Koonce’s comeback potential

Malcolm Koonce enters 2026 coming off a torn ACL and a somewhat stalled 2025 season, but he retains the upside that made him a 2023 sleeper. In that season he posted eight sacks and 54 pressures, a production level that could return if his health holds. Koonce also showed progress as a run defender in 2025, using his athleticism and hand‑strength more consistently than in prior years. He is slated to start opposite Maxx Crosby, rotating with Kwity Paye and Keyron Crawford, and his resurgence could be the difference between a middling defensive line and a genuine playoff contender. A return to his 2023 form would give the Raiders confidence heading into future seasons, especially with possible roster moves around Crosby. The combined impact of Koonce, Booker, Hemingway and the developing edge players could push the Raiders’ defensive line well above its current projections.

If Koonce thrives, the Raiders will have depth at a position that has been a weakness, allowing more flexibility in game planning. The synergy between a revitalized Koonce and the newly added interior talent could create a more balanced, aggressive front that keeps quarterbacks under pressure. This upward trajectory will be a pivotal factor as the Raiders look to climb the AFC West ladder in 2026.
