Fernando Mendoza Preseason Debut Ends an 8-Year Wait

The Fernando Mendoza preseason debut took one drive to go wrong and one more to go right. Las Vegas sent the No. 1 overall pick onto the field Thursday night in Arizona once Kirk Cousins finished his brief cameo, and the rookie's first series stalled on a holding penalty and ended in a punt. His second series ended in the end zone.

On that drive he went 4-for-5 for 47 yards and finished it with a 6-yard slant to second-year receiver Jack Bech. It was a small throw with a big footnote. According to CBS Sports, Mendoza is the first player taken first overall to throw a touchdown pass in his opening preseason game since Baker Mayfield threw two for Cleveland against the Giants in 2018 — an eight-season gap.

None of it changes the depth chart, and the Raiders still lost 27-14. But for a franchise that has spent most of a decade auditioning quarterbacks, this was the first live evidence that the guy they built the offseason around can run an NFL huddle. That's worth more than the final score of a game in August.

The Two Drives That Told the Story

Mendoza's night broke cleanly into halves of a personality. Drive one: 1-for-3, a holding flag that killed the down-and-distance, a punt. Drive two: crisp footwork, quick decisions, and a touchdown. He played four series in all, not counting an end-of-half kneel-down, and finished 10 of 16 for 97 yards with the one score. He also picked up six yards on the ground. The Las Vegas Review-Journal graded him as shaky in the pocket early and steadier as the night went on, which is roughly what you'd expect from a 20-something making his first professional start behind a second-team line.

What the Fernando Mendoza Preseason Debut Showed

The Throw to Jack Bech

A 6-yard slant sounds unremarkable until you consider what it requires: reading the leverage of a defender pre-snap, trusting a receiver to win inside, and putting the ball out before the window exists. Mendoza did it on a scoring drive he'd built himself. That single completion is the reason the highlight exists, and it's the throw scouts will replay.

The Wobble in the Pocket

The rough edges were real. Las Vegas committed seven penalties in the first half alone, and the second unit had what the Review-Journal described as operational issues — the sloppy pre-snap stuff that turns first-and-10 into first-and-20. The third quarter turned into a grind. Mendoza's completion percentage, 62.5%, sits well under the 72% he posted at Indiana last season.

The Numbers, in Perspective

Ninety-seven yards over nearly three quarters is not a headline stat line. Compare it to the starters: Cousins went 5 of 6 for 50 yards with a 13-yard touchdown to Michael Mayer, and Arizona's Jacoby Brissett was a perfect 5 of 5. Brissett and Gardner Minshew combined to complete all 15 of their first-half attempts for 123 yards and three scores. Veterans in vanilla preseason looks tend to look great. Rookies rarely do.

Why Kirk Cousins Still Opens Week 1

Nothing about the Fernando Mendoza preseason debut forces first-year head coach Klint Kubiak's hand, and that's fine. Cousins remains the No. 1 quarterback and is expected to start the opener. The Raiders signed a veteran precisely so the rookie wouldn't have to learn on the job in September, with an offense that already features Brock Bowers, running back Ashton Jeanty and new center Tyler Linderbaum. The realistic timeline is simple: Cousins holds the job while Las Vegas is in the race, and the keys change hands the moment the season slips away.

The Real Problem Wasn't the Rookie

Arizona scored on every meaningful first-half possession, and the Raiders' defense earned a D in the Review-Journal's grades. Fourth-round pick Jermod McCoy got beaten on two goal-line fades. Kicker Kansei Matsuzawa drew a landing-zone violation on a second-half kickoff and missed from 38 yards. The bright spot was punter AJ Cole, who averaged 61 yards on three attempts — which tells you how often the offense stalled. Also worth tracking: pass rusher Maxx Crosby's status remains uncertain as he works back from knee surgery.

What to Watch Before Week 1

Remember the résumé Mendoza brought with him. He won the 2025 Heisman Trophy, threw 41 touchdowns against six interceptions, and quarterbacked Indiana to a 16-0 season and a national title over Miami. He's one of only three players in the common draft era — with Joe Burrow and Cam Newton — to win a Heisman and a championship and then go first overall.

So watch the next exhibition for three things: whether Mendoza takes any first-team snaps, whether the pre-snap penalties clean up, and how quickly he gets the ball out when the pocket collapses. Preseason box scores are close to meaningless. Rhythm and decision speed are not, and both are visible on a Thursday night in August if you know where to look.
