Fernando Mendoza isn't walking into a starting job. The Raiders handed the keys to Kirk Cousins, a 37-year-old on a contract that guarantees him the job in year one, and stuck Mendoza on the QB2 line of the first depth chart of camp. So instead of a highlight reel, the story on Mendoza right now is a notebook. Literally. He's been carrying one around since high school, jotting down progressions and footwork notes, and his old coach says the kid used to skip lunch to review install sheets. That's the version of Mendoza the Raiders are banking on heading into Thursday's preseason trip to Houston.
Context matters here. This isn't some fifth-rounder trying to make a roster. Mendoza went No. 1 overall in April off a Heisman Trophy and a national title run at Indiana, the kind of resume that made Las Vegas comfortable pairing him with a bridge veteran instead of throwing him to the wolves in Week 1. Cousins signed a deal that's technically five years and $172 million but functionally a one-year, fully guaranteed $20 million prove-it, with club options tacked on. Translation: Cousins starts as long as he's playable, and Mendoza develops behind him with zero rush.
The tape backs up the studious reputation. In his preseason debut against Arizona, Mendoza went 10-of-16 for 97 yards and a touchdown across four drives, mostly working with the second-team offense. Head coach Klint Kubiak called him an 'ascending player' after the game, and for good reason. Mendoza became the first No. 1 overall pick to throw a touchdown in a preseason debut since Baker Mayfield back in 2018. That's a small sample, but it's a clean one, no turnovers, no panic reads, just a rookie operating like he's supposed to be there.
For fantasy purposes, none of this changes the calculus for 2026. Mendoza is sitting at QB27 in redraft ADP, which is another way of saying don't roster him unless your league starts about 30 quarterbacks. Cousins is QB1 in Las Vegas until he isn't, and there's no clean injury path or benching scenario on the horizon that makes Mendoza streamable this fall. If you're in a redraft league, he's a waiver-wire afterthought at best, someone you check in on only if Cousins' 38-year-old body starts breaking down mid-season.
Dynasty is where this actually matters. Mendoza is going in the 1.01-to-1.03 range of rookie drafts and sits around QB18 in consensus dynasty rankings, which undersells the long-term outlook for a former No. 1 overall pick with a Heisman on the mantel. Rookie quarterbacks who sit behind a bridge veteran for a year tend to have cleaner transitions than the ones thrown in immediately, so the redshirt-adjacent path here isn't a red flag, it's the plan working as designed. If you're building a dynasty roster and can grab him outside the top half of round one, that's value, not a reach.
The betting market has quietly priced Cousins as this team's guy for now, but keep an eye on how sportsbooks move Raiders win totals and Cousins' games-started props as the season goes. A 38-year-old quarterback on a fully guaranteed short-term deal, with a Heisman winner breathing down his neck and actually performing in preseason snaps, is exactly the kind of situation that can flip fast if Cousins struggles or gets banged up. Any hint of a midseason change would spike Mendoza's redraft value overnight, even in a limited role.
Thursday's game at Houston is another data point, not a verdict. Mendoza will again work mostly with backups against a Texans defense that's going to be light on starters too, so don't overreact to a big stat line or an ugly one. What matters is the same thing that's mattered all camp: is he processing fast, protecting the football, and building the kind of rapport with backup weapons that eventually becomes real chemistry with starters. The notebook habit says he'll show up prepared. Whether that translates to touches this year is still Cousins' call to make.
