Fernando Mendoza Preseason Debut: Why Cousins Got One Drive

The Fernando Mendoza preseason debut ran from the middle of the first quarter to the opening snap of the fourth, and it only played out that way because Las Vegas benched a veteran who had just scored. Kirk Cousins started Thursday night's exhibition opener, drove the Raiders 50 yards for a touchdown on the game's first possession, then handed the huddle to the rookie for the rest of the evening.

Mendoza, the No. 1 overall pick out of Indiana, finished 10 of 16 for 97 yards with a touchdown and no interceptions across four drives. He added six rushing yards and took one sack. Arizona won 27-14, a result nobody in Nevada will remember by September. The four possessions are the part the coaching staff actually paid for.

Here's the tension in that box score. Ninety-seven yards over four series is a quiet night by any standard. Yet Mendoza became the first No. 1 overall pick to throw a touchdown pass in his preseason debut since Baker Mayfield in 2018. Both facts are true at once, and figuring out which one carries more weight is the live question in Las Vegas.

Why the Starter Sat Down After a Touchdown

First-year head coach Klint Kubiak didn't yank Cousins because something went wrong. He pulled him because nothing did. One clean drive was enough of a look at a 15-year pro, and every remaining snap was worth more in the rookie's hands. Kubiak arrived from Seattle in February after coordinating a Super Bowl LX offense, so he knows exactly what he needs to see before Week 1.

Cousins remains the plan for the opener. Kubiak has said the job is his to lose, and per CBS Sports the Raiders intend to start him. But the contract tells the same story the substitution did. Reporting on the deal puts roughly $20 million guaranteed for 2026, with Atlanta absorbing $8.7 million of it under the offset from his old Falcons contract. Las Vegas is barely committed past this season.

What the Fernando Mendoza Preseason Debut Actually Showed

Strip away the No. 1 pick label and look at the reps. Mendoza worked through progressions instead of locking onto a first read, and the throws that landed were the kind that require timing rather than arm talent alone.

The 19-Yard Throw Through Three Defenders

His best ball of the night went to fellow rookie Malik Benson in the second quarter, a 19-yarder squeezed between three Arizona defenders. That's an anticipation throw, released before the window opens. Rookies usually hesitate on those and check down instead. He also hit tight-window work underneath, including a 14-yard completion to Dylan Laube.

Six Yards an Attempt, and Why It Isn't Damning

Do the math and Mendoza averaged about 6.1 yards per attempt, with a longest completion of 19 yards. That's a flat number in isolation. But preseason openers run on a stripped-down script, and Kubiak's scheme leans on rhythm throws underneath. The absence of deep shots says more about the call sheet than the arm.

The Fourth Drive, When It Started to Click

The most useful series was the last one. Mendoza completed four passes for 44 yards on his final possession and moved the Raiders into field goal range. Nearly half his production came on one drive, late, against defenders he had already seen twice. Progression within a single game is the thing scouts actually track.

How This Stacks Up Against Baker Mayfield

The Mayfield comparison is a fun stat and a shaky forecast. Mayfield opened 2018 on the bench behind Tyrod Taylor, took over in Week 3 after an injury, and Cleveland's timeline collapsed on its own. That's the realistic template here: a veteran holds the seat until the season stops cooperating. Kubiak's assessment after the game was deliberately unglamorous.

I see an ascending player. We just got to keep getting better.

Mendoza's own read was harsher. He said the night showed him he needs to grow a lot, and described his approach to bad plays as treating the next snap as a fresh chance. Benson, on the receiving end, praised the operation — the clear communication, the huddle. That's the unsexy stuff rookies usually botch.

The College Résumé He's Carrying

Context matters for the expectations. At Indiana last season Mendoza completed 273 of 379 passes for 3,535 yards with 41 touchdowns and six interceptions, ran for seven more scores, and went undefeated. The Hoosiers won their first national title, beating Miami 27-21, and he became the school's first Heisman winner. Only Joe Burrow and Cam Newton have matched that Heisman-plus-title-plus-No. 1-pick sequence in the common draft era.

He's also walking into a rebuild. Las Vegas went 3-14 in 2025 under Pete Carroll before Kubiak replaced him. A 97-yard preseason night doesn't fix that, and it was never supposed to.

What to Watch Before Week 1

Three things will tell you more than the debut did. Whether Cousins takes any meaningful snaps in the next exhibition, or the rookie gets the entire first half. Whether Kubiak dials up throws past 20 yards. And whether Mendoza starts operating with the ones instead of backups.

If you're drafting fantasy teams this month, treat Mendoza as a stash, not a starter — the path to real snaps most likely opens in October, not September. And if the Raiders fall out of the race early, expect that timeline to accelerate fast.
