A new head coach. A new system. And possibly a new identity.
The Las Vegas Raiders are about to flip the script — and the defense may never look the same again.
Klint Kubiak Announces Major Defensive Overhaul — Raiders Set for Dramatic Shift to 3-4 Scheme
The Las Vegas Raiders aren’t just tweaking their defense. They’re rebuilding its DNA.
Speaking at the NFL Combine in Indianapolis on Feb. 25, new head coach Klint Kubiak confirmed a seismic change: the Raiders will transition to a 3-4 base defense under newly appointed defensive coordinator Rob Leonard.
“I do see us being a base 3-4 team,” Kubiak said. “I see us being able to four down (linemen) well. I think Robby can be really multiple with his fronts.”
Translation? Flexibility. Pressure. Reinvention.
For years, the Raiders operated primarily out of a 4-3 base under former coordinator Patrick Graham. That structure emphasized four down linemen and three linebackers. Now, the blueprint shifts to three linemen and four linebackers — a system that demands different personnel, different instincts, and a different mindset.
What This Means for the Roster
This isn’t just X’s and O’s.
Switching to a 3-4 base means the Raiders must reinforce a linebacking corps that is currently thin. It also creates urgency to find or develop a true nose tackle — the anchor responsible for controlling the middle of the line.
And then there’s Maxx Crosby.
The star pass rusher’s future in Las Vegas has been clouded by trade rumors. But Kubiak made his stance clear.
“That’s a guy we really want on our team,” he said. “It’s as simple as that. We want Maxx to be a Raider.”
In a 3-4 scheme, Crosby could shift into an edge linebacker role — similar to how elite hybrid defenders operate in Baltimore or Miami systems. That versatility could unlock new dimensions of his game.
“I’m really excited about working with Maxx this year,” Kubiak added.
That statement alone may calm a fanbase anxious about potential roster upheaval.
Why Rob Leonard?
Kubiak’s decision to hand the defense to Rob Leonard raised eyebrows — not because Leonard lacks credibility, but because this marks his first time running a defense at the NFL level.
However, Leonard arrives with serious influences.
He previously coached under Seahawks head coach Mike Macdonald in Baltimore and worked within Brian Flores’ defensive structures in Miami — two systems known for hybrid 3-4 fronts, creative blitz packages, and heavy defensive back usage.
But Kubiak insists Leonard isn’t just borrowing ideas.
“He’s got a lot of impressive influences, but he has his own identity as well,” Kubiak said. “He had a plan. He knew what he wanted to do and the type of players he wanted to do it with.”
That clarity sealed the deal.
A Collaborative Reset
This wasn’t a top-down mandate. Kubiak emphasized that the shift to a 3-4 was a collaborative decision.
“We’re in this thing together,” he said. “You have to have a starting point and that to me would be a base 3-4.”
That starting point now shapes everything: free agency priorities, draft strategy, player development, and potentially blockbuster trade decisions.
Because system changes ripple.
They influence which veterans stay. Which prospects rise on draft boards. Which positions become premium overnight.
Identity in Transition
The Raiders are entering a new era under Kubiak. A Super Bowl champion just weeks ago with Seattle, he now faces the challenge of redefining a defense that has struggled with consistency in recent seasons.
The move to a 3-4 base suggests aggression and adaptability. It signals a desire to disguise pressure and create matchup problems. It also demands smart personnel moves in the coming months.
Whether Maxx Crosby becomes the centerpiece of that evolution remains to be seen — but Kubiak’s message was unmistakable: he wants him in silver and black.
The Raiders aren’t standing still.
They’re reshaping who they are — from the front seven outward.
And the transformation has officially begun.
