J.J. McCarthy didn’t need all the practice reps to play like a veteran. The Vikings’ second-year quarterback’s preparation came from mental simulations, turning weeks of watching on the sideline into what happened Sunday. In Detroit, he guided the Vikings to a 27-24 upset over the Lions.
Minnesota stayed efficient in critical moments and executed with confidence inside one of the NFC’s loudest environments. For a player who entered the league surrounded by questions, McCarthy’s performance hinted at something deeper than raw talent. He’s a quick study, too.
Inside the Mental Reps That Shaped J.J. McCarthy’s Return
According to ESPN’s Peter Schrager, McCarthy’s preparation went far beyond the playbook. While sidelined with an ankle injury, he could not practice physically, so the Vikings had him mentally simulate entire drives. He rehearsed calling protections, reading defenses, and making pre-snap adjustments from the sideline.
“So they had J.J. McCarthy simulating all the stuff at the line of scrimmage,” Schrager said. You can’t move, you can’t run, you can’t throw, but do you have all the calls? Do you know how to get everyone into alignment?”
That work showed up against Detroit. McCarthy had his highs and lows, making just his third career start. He completed 14 of 25 passes for 143 yards with 2 touchdowns and 1 interception, and added a rushing touchdown. His biggest throw, a third-and-five strike to Jalen Nailor to ice the game, kept the Vikings’ season alive and quieted early critics.

Still, there are concerns. The Vikings offense ranks just 27th in PFSN’s OFFi. McCarthy averaged a mere two yards per dropback over the final three quarters, accumulating just 48 yards on 24 attempts.
A big plus for McCarthy is that the Vikings operated smoothly. The team had no delay-of-game or formation penalties. What stood out most was how seamlessly the offense operated under pressure. The Vikings used motion to simplify reads and trusted McCarthy to handle audibles at the line.
It was a stark contrast from the stalled drives and communication issues that had plagued earlier games. With veteran quarterback Carson Wentz out for the season, McCarthy’s poise and mental discipline give Minnesota something real to build around.
After missing 24 games since being drafted, McCarthy is still learning, but the foundation is there. His mental preparation and execution at the line showed why O’Connell continues to trust him. Under O’Connell, there will always be a plan for McCarthy.
