J.J. McCarthy’s Vikings preseason debut was one series, but it left a lasting impression. He led a 13-play opening drive that ended in a field goal, showing poised command and a willingness to use his legs to extend plays. Tears at kickoff gave way to a clean, efficient performance in a live game against an unfamiliar defense, signaling the start of a long-term development arc for Minnesota’s quarterback of the future.

McCarthy connected with Addison and built chemistry with Jefferson in offseason work, though both veteran receivers were held out. Addison posted 33 yards on three grabs, including an 18-yard diving catch, while McCarthy showed mobility on fourth-and-4 runs and a readiness to improvise. Missed timing to Lucky Jackson and a high pass to Jordan Mason were hiccups, but the day’s biggest takeaway was the quarterback’s mobility and the clean operation—no penalties, sacks, or turnovers on the drive—a foundation on which Kevin O’Connell can layer more complex plays as camp progresses.

O’Connell framed the moment as a step in a precious process, highlighting layers of decision-making as McCarthy learns to read edge-rushers and orchestrate a next-gen offense. The pairing with Addison, combined with McCarthy’s athleticism, gives Minnesota intriguing upside if the rookie’s growth continues through August and into the season. The mood afterward blended emotion with optimism: McCarthy felt the moment, Addison flashed a connection, and the Vikings left U.S. Bank with momentum toward a long, patient quarterback development trajectory.
