Is Week 8 Fernando Mendoza time? Raiders' losing streak puts Kirk Cousins under pressure

Kirk Cousins hasn’t played his way out of the Las Vegas Raiders’ starting quarterback job. But if the losses keep piling up, that might not matter. The Raiders are coming off a 41-17 blowout loss to the New England Patriots, their second consecutive defeat after opening the 2026 season 3-0. With first-year head coach Klint Kubiak trying to establish a new foundation in Las Vegas, the question is becoming less about whether veteran Cousins can still run an NFL offense and more about how long the team can afford to delay the future: Fernando Mendoza.

The No. 1 overall pick in the 2026 NFL Draft remains the obvious long-term answer at quarterback. The challenge for Kubiak is determining when the benefits of getting Mendoza on the field outweigh the value of keeping Cousins under center.

The next two weeks could provide that answer

The Raiders face Buffalo before taking on the Los Angeles Rams. If both opponents deliver convincing defeats, Las Vegas could enter Week 8 with a losing record, mounting pressure and a compelling reason to give Mendoza his first NFL start against the New York Jets. That scenario is becoming increasingly plausible, although it would take more than one bad afternoon from Cousins to make the change inevitable.

The recent results have been ugly, but the quarterback’s season has not been a disaster. Cousins threw three touchdown passes in each of Las Vegas’ first three games, helping the Raiders jump to a 3-0 start. He has managed just three passing touchdowns combined over the past two contests, a sharp decline in production that has coincided with the team's losing streak.

Even so, Cousins remains tied for second in the NFL with 12 passing touchdowns in 2026. His broader efficiency numbers also suggest that the 38-year-old still has something to offer. Cousins ranks among the league’s top 10 quarterbacks in expected points added per dropback (EPA), success rate and completion percentage over expected. He also ranks fifth in win probability added among quarterbacks with at least 100 pass attempts.

Those metrics complicate the argument for benching him immediately. Cousins can still process a defense, distribute the ball quickly and get it to the right playmakers. Brock Bowers, in particular, remains an obvious target for an offense looking to manufacture consistent production.

The physical limitations are real

Cousins can struggle when pressure arrives, and his reduced mobility can turn a manageable pass-rush situation into a sack. Those shortcomings were known when Las Vegas brought him in, however, and they don't automatically erase the value of his experience or his ability to operate the offense.

The 41-17 loss to New England exposed problems that went beyond the quarterback. Replacing Cousins would not necessarily fix the offensive line, the protection breakdowns or the broader issues that have contributed to the Raiders' slide.

That distinction matters because a quarterback change should be about giving the team a better chance to win, not simply finding someone to blame for a bad result.

Why Week 8 could be Mendoza’s moment

If the Raiders lose to Buffalo and the Rams, the circumstances surrounding Mendoza’s potential debut would change considerably. At that point, Kubiak would have to evaluate whether continuing with Cousins gives Las Vegas its best chance to salvage the season or whether the team should begin investing meaningful game experience in the quarterback it selected first overall.

Week 8 against the Jets stands out as a logical opportunity. It would give Mendoza a defined target date after two difficult matchups, allowing the coaching staff to assess Cousins’ performance, the team's record and the rookie’s readiness before making a decision.

There is also a developmental argument for making the move sooner rather than later. Every week Mendoza spends on the sideline is another week without live NFL experience, and the Raiders need to learn what they have in their franchise quarterback.

But starting him against the Jets would not necessarily mean the road gets easier afterward. Las Vegas faces a challenging stretch against San Francisco, Seattle and Denver. Those defenses could test Mendoza’s ability to recognize pressure, make quick decisions and protect the football. Throwing a rookie into that sequence without sufficient preparation could create problems of its own.

The Raiders must therefore weigh two competing priorities: giving Mendoza the experience he needs to develop and avoiding a situation in which his first starts become a series of difficult lessons behind a struggling offense.
