Klint Kubiak's plan for the Raiders' QB room in 2026 is patient and deliberate — Kirk Cousins is the clear Week 1 starter, while No. 1 overall pick Fernando Mendoza is in a "redshirt-lite" development role.
Here's the full picture:
Cousins is the bridge starter. He signed a flexible 1-year deal and is ahead of schedule in his Achilles recovery. Kubiak said Cousins "has played really good football for us this time of year" in OTAs. Cousins has prior experience with Kubiak's Shanahan system from their time together in Minnesota, making him a seamless fit (from the Kirk Cousins page).
Mendoza is being brought along slowly. Kubiak has been explicit about not rushing the rookie, even citing roster holes (WR depth, OL depth, defense) as reasons to hold him back — and said he wouldn't throw Mendoza in even if Cousins got hurt. Minority owner Tom Brady reinforces this "slow-play" philosophy, calling it "a tragedy" to force young QBs to play early (from the Las Vegas Raiders page).
No actual competition. Multiple reports confirm Cousins is the frontrunner. Kubiak's message is clear: the 2026 roster isn't built to support a rookie QB, so Mendoza gets a developmental year while Cousins holds the wheel (from the Raiders team page, citing the "Raiders could make stunning Fernando Mendoza Week 1 move" article).
Expert take: On Fantasy Football Today, they noted the uncertainty — "Kirk Cousins at this point or just a not-ready-yet Fernando Mendoza... there's a lot of things that can go wrong. But the upside to me is worth it" — framing the Raiders offense as a high-variance but potentially rewarding bet.
Bottom line: It's Cousins's job to open 2026. Mendoza is the future, but Kubiak is building for 2027 and beyond — not rushing his rookie into a lineup he doesn't think is ready yet.
