The 2026 first overall pick and reigning Heisman winner lands in Las Vegas with real pedigree after a 16-0 national title run and a 72% completion year worth 41 touchdowns. The catch for fantasy managers is timing: Kirk Cousins is penciled in to open the season, so Mendoza projects as a redshirt-then-takeover arm rather than a Week 1 plug-and-play. That holds his ECR near QB29 (167 overall) and stamps him a late-round dart in single-QB formats, with far more juice in superflex and dynasty rookie pools.

The supporting cast is a mixed bag. Brock Bowers and Ashton Jeanty give him two genuine difference-makers, and a Tyler Linderbaum-anchored line plus Klint Kubiak's scheme help, but the receiver room of Tre Tucker, Jalen Nailor and Jack Bech is thin. Modeled output lands around 2,844 yards, 16.6 scores and 232 rushing yards for roughly 193 fantasy points. Stash him, start him later.
