HENDERSON, Nev. — Las Vegas Raiders coach Klint Kubiak saw something special in rookie quarterback Fernando Mendoza during Thursday night's preseason opener against the Arizona Cardinals. Mendoza, a sixth-round pick out of Cal, completed 10 of 16 passes for 97 yards and a touchdown, leading the Raiders' offense across four series that amounted to 18 plays. The team ultimately fell 27-14, but the performance left a lasting impression on the coaching staff.

Kubiak, in his first season as head coach, was particularly struck by Mendoza's composure. "He went out and executed the way that he does in practice," Kubiak said on Friday. "Some guys get to the game and things change on them, and they move fast and freak out. He was the opposite."

Mendoza had spent most of training camp working with the second-team offense. His only snaps with the starters came after Kubiak held veteran quarterback Kirk Cousins and defensive end Maxx Crosby out of practice following a scuffle between the two. That incident, though brief, opened a window for Mendoza to run with the first unit. Against the Cardinals, he showed the poise and accuracy that had drawn the Raiders' attention during the draft process.

Cousins, who started the game, went 5-for-6 for 50 yards and a touchdown in his lone series, finding tight end Michael Mayer for a 13-yard score on the opening drive. Third-string quarterback Aidan O'Connell closed out the game in the fourth quarter. Despite the clear hierarchy, Kubiak made it clear that the competition is not closed.

"That's something that we're talking about as a coaching staff right now," Kubiak said. "Whether it's Aidan O'Connell, Kirk or Fernando, all three of those guys deserve first-team reps. We've got to put a plan together on how we're going to split them up."

Mendoza's performance might have strengthened his case for more practice time with the starters. Yet Kubiak was quick to reinforce that the starting job remains Cousins' to lose, citing the veteran's efficient outing and leadership. But Mendoza's self-assessment was less forgiving. The rookie focused on the throws he missed and the reads he botched, highlighting that his timing and anticipation still need work.

"The best quarterbacks I've been around are the ones that are hard on themselves," Kubiak said. "... I think he played good football last night."

This balancing act—praising a promising rookie while keeping a veteran starter in place—is a delicate dance for any coaching staff. The Raiders are in a transitional phase, building around a defense anchored by Crosby and an offense that features a mix of young talent and seasoned players. The quarterback room, now with three legitimate candidates for first-team reps, gives Kubiak a luxury of depth but also a potential distraction if not managed carefully.

As the preseason continues, the Raiders will likely rotate their quarterbacks with the first-team offense in practices and games. Kubiak's comments suggest that Mendoza has earned a longer look, but Cousins remains the front-runner. For now, the competition is healthy, and the team's direction remains focused on the regular season opener.
