The Las Vegas Raiders spent months constructing a patient development plan for Fernando Mendoza. That plan ended Tuesday, when a deadline-day trade sent veteran Kirk Cousins to the Minnesota Vikings and elevated the rookie into the starting quarterback role sooner than the organization had intended.
Mendoza, the first pick in the 2026 draft and a Heisman Trophy winner and national champion, now takes over a 4-5 team with a daunting first assignment: a start against the defending Super Bowl champion Seattle Seahawks. He will be the fifth quarterback to make his first career start against a Mike Macdonald defense. The previous four went 0-4 with no touchdown passes and a combined nine interceptions.
Coach Klint Kubiak expressed confidence Thursday in how the rookie has approached the season behind the scenes. "It shouldn't be a whirlwind if he's been preparing the right way each week," Kubiak said. "At some point, he knew he was going to get an opportunity, and so he's been preparing that way since April."
The sit-and-learn approach was deliberate from the start. Once the Raiders knew they held the top pick and would use it on Mendoza, they hired an offensive-minded head coach who had just won the Super Bowl as Sam Darnold's offensive coordinator, signed Cousins in free agency and declared him the starter at every step. Minority owner Tom Brady has been vocal about his belief that rookie quarterbacks need more development time than the NFL usually allows, and his voice carries significant weight in the building. The staff was built around the rookie's needs, with Kubiak setting the organizational tone, former Seattle assistant Andrew Janocko hired as coordinator and longtime NFL coach Mike Sullivan brought in as quarterbacks coach. Sources with knowledge of the situation say Sullivan's involvement with Cousins and daily game preparation has been minimal compared to his direct coaching of Mendoza.
Sullivan has seen a version of this before. He was on the Giants' staff in 2004, when Eli Manning sat behind veteran Kurt Warner for the first nine games of his rookie season before starting the final seven. Those Giants were 5-4 when they made the switch. These Raiders are 4-5.
Speaking Wednesday, Mendoza offered heartfelt thanks to Cousins, saying the veteran "had me with open arms and has taught me so many things, whether it's film study, how to operate as a starting quarterback, all the different multifaceted approaches that have made him so successful, he has shared with no restrictions or constraints." The Raiders had hoped that apprenticeship would last longer. As recently as last weekend, some in the organization wanted to keep Cousins past the trade deadline and delay Mendoza's debut, possibly until after the Week 13 bye. Minnesota called about Cousins before last weekend, and a disastrous performance by Carson Wentz on Monday night accelerated both teams' timelines, leading the Vikings to offer a third-round pick.
History offers no clear verdict on whether the Raiders' caution was right. Per ESPN Research, 41 quarterbacks were selected in the top 10 from 2006 to 2025, and only six did not start at least one of their teams' first eight games as rookies. Just two of those six, JaMarcus Russell and Jared Goff, went first overall, with Jake Locker, Patrick Mahomes, Michael Penix Jr. and J.J. McCarthy rounding out a group with a wide range of outcomes. Recent seasons cut both ways: C.J. Stroud won Rookie of the Year after starting immediately in 2023, while Anthony Richardson Sr.'s instant promotion that same year produced damaging results. In 2024, Drake Maye started in Week 6 and proved he had been ready all along, while Jayden Daniels and Bo Nix thrived as Week 1 starters. The ideal remains the 2017 Chiefs, who let Mahomes sit behind Alex Smith for essentially a full season.
Even the Raiders acknowledge the unknowns. Mendoza's only live action came in a late series during a Week 5 blowout loss in Foxborough, a far cry from diagnosing a championship defense from the first snap. The team does not yet know how he will handle touch throws under game conditions or pressure in his face. Mendoza said the Raiders "have done a fantastic job in aiding my development, and I can't thank them enough, and now it's my turn to do my one-eleventh." Kubiak said no single practice moment convinced him the rookie was ready, adding: "It's consistency, playmaking, knowledge of our scheme. Just his daily preparation has been up to standard, and now he's got to go prove it in the game."
Whether the Raiders' setup, built around a veteran mentor, a quarterback-friendly staff, a more developed offensive line and a pair of star tight ends, will be enough is a question the franchise may second-guess for years. But the timeline is no longer theirs to control. Ready or not, Mendoza's time is now.
