Fernando Mendoza makes an early impression in Raiders preseason, but Kirk Cousins remains the No. 1

The Las Vegas Raiders entered this stretch with their quarterback pecking order set for the regular season, but Fernando Mendoza’s preseason debut complicated the conversation anyway. According to CBS Sports, Mendoza flashed the kind of playmaking that makes coaches and fans wonder what the future could look like, even if he is not the current answer at the top of the depth chart.

In the preseason opener, Kirk Cousins, the Raiders’ free-agent acquisition at quarterback, was named the starter and led the offense. CBS Sports reports that Cousins is also expected to run the Week 1 game plan, which keeps the immediate status quo in place. Still, the existence of a backup who can create momentum in real time raises the stakes for every drive that follows, particularly when the regular season is close enough that coaches start protecting the starting unit while also evaluating who can change a game if needed.

Mendoza’s performance, as described by CBS Sports, did not replace Cousins as the team’s plan, but it did give the Raiders a reason to monitor how his skill set translates under pressure. The central theme in the report is not that Las Vegas suddenly has a new starter, but that Mendoza’s flashes made the timing of the quarterback decision feel less distant than it would have otherwise.

In the NFL, a quarterback competition often becomes most visible at the margins. Even when one player is clearly first on the depth chart, the backup reps matter for development, for third-down packages, for red-zone efficiency, and for the ability to maintain offensive identity if the starter has to come out. CBS Sports’ framing emphasizes that Mendoza looked like more than a placeholder, suggesting the Raiders may have more options than they did before the preseason snaps.

For Cousins, the path is straightforward on paper: start Week 1, keep the offense consistent, and reinforce trust with timing, command of protections, and decision-making. Yet preseason is also where backup quarterbacks can quietly influence how conservative or aggressive a team is willing to be later in the roster’s timeline. If Mendoza’s play continues to trend upward, the internal debate may shift from “who is next” to “how quickly can the next option be trusted,” even if it is not immediately.

There is also a broader roster-building context. The quarterback position is rarely evaluated in isolation, because a quarterback’s effectiveness depends on scheme fit and personnel strength, especially at receiver and in the protection game. Mendoza’s emergence, described as “flashing” ability, invites a practical question for the Raiders coaching staff: is the offense functioning through Cousins’ leadership traits alone, or can similar concepts be executed by a different stylistic profile under game conditions?

For now, the simplest takeaway is that Cousins remains the starter and Mendoza remains the backup, as CBS Sports reports. But the more meaningful subplot is how Mendoza’s next opportunities will be handled. Watch whether the Raiders continue to give him work that resembles regular-season responsibilities, and whether his decision-making holds up as reps become less exploratory and more strategic. If he can sustain the early promise, the Raiders’ quarterback picture will stay a live issue well past the preseason.
