“We put him through as much stress as we can": Raiders’ Klint Kubiak reveals what Fernando Mendoza must prove before taking over from Kirk Cousins

The Las Vegas Raiders have found an unexpected advantage in Kirk Cousins, whose strong start to the 2026 season has given the team stability at quarterback. His performances have also allowed rookie Fernando Mendoza to develop without being rushed into the starting role. However, head coach Klint Kubiak wants the No. 1 overall pick to be ready whenever his opportunity arrives. Kubiak recently offered an insight into how the coaching staff is preparing Mendoza, making it clear that limited playing time will not lower expectations for the young quarterback.Klint Kubiak puts Fernando Mendoza under pressure during Raiders practicesMendoza entered the NFL with considerable expectations after the Raiders selected him with the first overall pick. The team wanted a young quarterback who could become its long-term leader, but it also understood the value of bringing in an experienced player to guide him through his first professional season.Cousins has turned out to be an excellent option. Despite questions about his future following an underwhelming spell with the Atlanta Falcons, the veteran has delivered impressive numbers in Las Vegas. Through his first eight games with the Raiders, he ranks second in the NFL with 19 passing touchdowns and third with 2,124 passing yards. The team is also holding a 4-4 record heading into Week 9.That production has made it difficult for the coaching staff to consider a change at quarterback. Cousins understands Kubiak's system and has given the Raiders a reliable option while Mendoza continues learning from the sidelines.Kubiak, however, does not want the rookie to mistake his backup role for a reduced level of responsibility. Speaking to reporters on Wednesday, the Raiders head coach explained how the staff is testing Mendoza's readiness despite his limited opportunities to work with the first team.“I think when you are the backup quarterback and you don’t get a ton of reps, I think we all find out together on Sunday how ready he is,” Kubiak said of Mendoza. “We put him through as much stress as we can. Coach [Mike] Sullivan does a phenomenal job, coach Andrew [Janocko], and when his time is called, whether he gets three more years of reps or he gets one more day of reps, he has to be ready.”The message is straightforward. Mendoza may not receive the same number of practice opportunities as Cousins, but the coaching staff expects him to handle the pressure when called upon. An injury, a sudden change in form or an unexpected game situation could put the rookie in charge without much warning.Kubiak has repeatedly backed Cousins as the starter, leaving little doubt about the current quarterback hierarchy. Mendoza has already received some playing time this season, giving the Raiders an early look at his potential. Still, his biggest test will come when he has to manage an entire game.Kirk Cousins explains his approach to handling pressureCousins has offered more than just production during his first season in Las Vegas. His experience has also helped the Raiders navigate difficult situations, including their comeback victory over the New York Jets.The veteran threw three touchdown passes and added a rushing score as Las Vegas recovered from a nine-point deficit to win 38-31. His ability to remain composed played a major role in the result.Cousins recently explained how he approaches those moments.“I’ve always tried not to ride the roller coaster,” Cousins said. “But for the most part, I just try to be steady because I know in this league there are going to be ups and downs. Just stay the course and keep playing. … You’ve just got to believe that if you keep playing, there’s a good chance you’ll be right there in the fourth quarter.”That mindset is one of the qualities Mendoza can observe while learning behind him. Cousins will now face another challenge against the San Francisco 49ers in Week 9, with the Raiders looking to improve to 5-4.For Mendoza, the immediate task remains preparation rather than waiting for a starting opportunity. Cousins is giving Las Vegas results, but Kubiak's message suggests the rookie will be judged on how well he responds when the team needs him.Get the latest Sports News and Live updates.
