The Raiders Are Walking Into 2026 With a Defense Built on Wishes
Three bad things happened to Las Vegas's defense in roughly 72 hours, and the one that might sting longest isn't even the most dramatic. Chris Collier landing on Injured Reserve on August 1 is the headline. Jermod McCoy sitting at Questionable despite being cleared for training camp just weeks ago is the slow-burn worry. But Devin White signing with Detroit—a former All-Pro linebacker who posted 174 tackles and 2.5 sacks across every game of a 3–14 season—is the one that tells you the most about where this roster actually stands. When a player of that profile takes his time in free agency and then chooses somewhere else, it usually means the competing offer wasn't compelling enough to overcome the destination. The Raiders couldn't close that deal, and now the linebacker depth chart reads Buddy Johnson, Patrick Johnson, and Cameron McGrone.
That depth chart context matters enormously when you set it against what the 2025 season actually revealed. Las Vegas went 2–5 in games decided by a touchdown or fewer—a 29% win rate in close games from a team that finished 3–14 overall. The defense's inability to make a stop when the margin was thin wasn't a special-teams problem or a quarterback problem in isolation; it was a systemic execution failure, and White was one of the few veterans capable of anchoring a late-game defensive stand. His departure doesn't just cost tackles. It costs the one linebacker who had proven he could function at volume in this scheme under defensive coordinator Rob Leonard.
The McCoy situation compounds everything. A cornerback who missed all of 2025 with a knee injury was supposed to represent the secondary's upside story—a reclamation project that costs nothing if it fails and pays dividends if it works. The front office was reportedly exploring external options, including Terrion Arnold, after McCoy's status slipped back to Questionable. That's the right instinct. A defense that lost its most productive linebacker to free agency, has its top cornerback recovery project in medical limbo, and just sent a pass rusher to IR before training camp even opens cannot afford to bet on internal development alone.
Isaiah Pola-Mao is still here—92 tackles and two interceptions in 2025, a reliable presence in the secondary—and the depth chart at corner and defensive end has names attached to it. But reliability at safety doesn't fix a linebacker corps that has never been tested at this level, and names on a depth chart aren't the same as proven production. The Raiders' offseason has been genuinely active on the offensive side: Mendoza signed, Jeanty healthy, Bowers ready, Tucker available. The offensive infrastructure is the most coherent it has looked in years. That makes the defensive disarray harder to rationalize, not easier. You can't build a winning team in 2026 by hoping Ashton Jeanty runs for 200 yards every week while the defense gives up 24.
My read is this: the front office has a narrow window before the season begins to address what the roster currently cannot answer. The case for pursuing available veteran help at linebacker and corner is straightforward—this defense, as currently constructed, is being asked to replace proven production with projection. That worked fine as a plan B. It is a riskier proposition as plan A. The 2025 Raiders lost close games at a rate that exposed their execution ceiling. Adding youth and uncertainty to the defensive side of the ball, while the offensive core matures, is the kind of imbalance that turns a potential step forward into another long autumn.
