Even so, Mendoza has been putting in private prep, training with former quarterback and quarterbacks coach Brian Griese to learn the West Coast offense Klint Kubiak plans to run in Las Vegas. The focus is on foundational details like footwork and operating efficiently from under center to establish timely, repeatable mechanics.
Griese and Kubiak worked together with the San Francisco 49ers in 2023, so Mendoza’s choice to train with Griese is viewed as a smart, compatible fit. Reported progress suggests he’s already ahead of expectations in absorbing the system and the terminology he’ll encounter in Vegas.
Key emphasis in the work includes play-action timing, ball handling, and the synchronization of footwork with route concepts and the expected release point. Griese is stressing how the timing should match the routes and how the ball should come out to maximize seamless operation with the offense.
The quarterback competition in Las Vegas will be interesting once camp opens, especially with Kirk Cousins on the roster and familiar with Kubiak’s system. Mendoza’s proactive preparation could help close the gap, making the training camp matchup between him and Cousins one to watch.
Overall, Mendoza’s early preparation signals a deliberate path to adapting to the Raiders’ style, even before he can practice with the team. Observers will be watching his development closely as the draft approaches and into training camp to gauge his readiness for the pro game.
